title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	Education of Interactive Panorama-design in Architecture
doi	https://doi.org/10.52842/conf.ecaade.1999.223
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 223-229
summary	This paper mainly discusses the importance of interactive panorama in design, and its education in the MDes program, which will run at Yildiz Technical University in the year 2000. The first part of the paper summarizes the potentials of current interactive panorama technique, which was "A popular form of the public entertainment" in 19th-century. Then, it compares the real-world experiences with observations in an interactive panorama. This comparison is carried out together with technical aspects i.e. limitations, audio-visual effects, composite techniques, live video input, and conceptual aspects i.e. camera actions, natural phenomenon. The technical discussion in the paper is concentrated on the examples from newly developed tools such as Nodemedia, Electrifier, Wasabi Software, and Skypaint as well as Apple QuickTime VR Authoring Tool. The second part underlines the role of interactive panorama technique in design. In this part, the paper also summarizes how to use the technique at the beginning and, during creation of the design and in its presentation, taking the installation advantages of sound, vision, text and transition effects. The third part concentrates on the interactive panorama design as an individual project, offered in the MDes program. Then it explains how the preliminary courses were planned for this individual project and summarizes the content of the course formulated through the linear and non-linear structures of the media. Finally, considering with the future development of interactive panorama technique, the last part of the paper discusses the possible results of this education method.

title	Será que na Era Digital o Desenho Ainda é a Marca Pessoal do Arquiteto? (Will Drawings still be the Architect's Individual Mark in Digital Era?)
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 383-387
summary	Technological innovations are driven in such dynamism, which do not favour a reflective process. Novelty is absorbed, in many cases, without criticism, in an immediate way. Concerning Architectural and Urbanism Education, a systematic reflection on the impact of new information technology to students training should not be omitted. As visual codes are the prime expression of architects, it is important to evoke the assumption of drawing as a language in order to evaluate it in regard to the new reality. Intending to broaden the discussion on these issues and to pose in theoretical means practical matters on didactics, it will be investigated the implications of computational resources - specially CAD systems - in graphic expression, in design thinking and their consequences to the education of future architects. Learning visual thinking, and being skillful at traditional as much as digital means, challenges today’s student.

title	A Generative Approach to Variations in Production Processes
source	International Conference on Generative Art
summary	Many work procedures in generating various types of products (such as execution of recipes for food, work operation for leather, procedures for conservation of vegetables, factory workmanship processes, etc) are characterised by precise procedural steps. Each step can be defined, at the proper detail level, in terms of kind of operations, input conditions, output results; then, a complete procedure can be exploited as a set of partially ordered steps of such a kind of functions. The formalisation of such a steps allows to evaluate procedures devoted to the same goal, introducing metrics for comparing them in terms of originality or imitation. Furtherly, a contextual analysis of different procedures devoted to similar goals allows to verify possible variations in the procedures, introducing innovation and changes on the basis of the available examples. The changes can be automated through proper algorithms, just using techniques of learning by examples, in the respect of verifiable constraints. The results can be verified, and used again as a new enriched experienced basis to improve the innovation procedures. The paper will describe the approach for the analysis and the description, will propose an experienced metric, and will show examples of generation of new innovative methods based on the automated analysis of successful examples. All the practical examples will be expressed in cooking recipes, described, compared in terms of plagiarism with properly defined metrics, improved with automatic generation based on experience and examples, properly checked and validated.

title	On the Translation of Design Data into Design Form in Evolutionary Design
source	International Conference on Generative Art
summary	The marriage of advanced computational methods and new manufacturing technologies give rise to new paradigms in design process and execution. Specifically, the research concerns itself with the application of Generative and Evolutionary computation to the production of mass-customized products and building components. The work is based on the premise that CAD-CAM should evolve into a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs that exhibit common features. The concept of Parametric Design is well established, and chiefly concerns itself with generating design sets that exists within the boundaries of pre-set parametric values. Evolutionary Design extends the notion of parametric control by using rule-based generative algorithms to evolve common families of individual design solutions. These can be optimized according to particular criteria, or can form a wide variety of hierarchically related design solutions, while supporting design intuition. The integration of Evolutionary Design with CAD-CAM, in particular the areas of flexible manufacturing and mass-customization, creates a unique scenario which exploits the full power of both approaches to create a new design-process paradigm that can generate limitless possibilities in a non-deterministic manner within a variable search-space of possible solutions.This paper concerns itself with the technical and philosophical aspects of the codification, generation and translation of data within the evolutionary-parametric design process. The efficiency and relevance of different methods for treating design data form the most fundamental aspect within the realm of CAD/CAM and are crucial to the successful implementation of Evolutionary Design mechanisms. This begins at the level of seeding and progresses through the entire evolutionary sequence, including the codification for evaluation criteria. Furthermore, the integration of digital design mechanisms with CAM and CNC technologies requires further translation of data into manufacturable formats. This paper examines different methods available to system designers and discussed their effect on new paradigms of digital design methods.

title	The Management and Visualisation of Document Collections Using Formal Concept Analysis
source	Griffith University, Australia
summary	This thesis proposes a methodology, notation/theory, and software framework for organising documents using formal concept analysis. The documents are organised for the purposes of retrieval and analysis using background information in the form of a taxonomy of terms. An emphasis is placed on the development of a methodology that employs scalable computer programs to assist humans in the process of organisation, retrieval and analysis of document collections.The text retrieval community has also been concerned with the organisation of documents. The work outlined in this thesis makes use of the results of the text retrieval community at its lowest layer. Above this layer formal concept analysis is used as a mechanism to allow users to organise document collections using views determined by small numbers of attributes. These views, also known as scales, can make a mixture of coarse and speci c distinctions between documents, and are either selected or created by the users to make precisely the distinctions between documents that are important to their current tasks.The primary tool for the presentation of the results of formal concept analysis is a line diagram. The e ectiveness of the presentation of information contained in a line diagram is heavily dependent on the quality of the diagram. To support users in arriving at a quality diagram for a newly created view, graph drawing algorithms are adapted to the special case of determining a good layout for a concept lattice. This task is di erent from traditional graph layout problems because lattices exhibit a high degree of structure which should be exploited and made evident in the nal diagram. A new layout algorithm is proposed that combines a layered diagram approach and an additive diagram methodology. This new hybrid algorithm is shown to produce better diagrams than other adapted graph drawing algorithms.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

summary	The functions supported by commercial CAAD software are drawing, construction and presentation. Up to now few programs supporting the creative part of architectural problem solving have become available. The grand hopes of symbolic AI to program creative architectural design have been disappointing. In the meantime, methods called referred to as New AI have become available. Such methods includegenetic algorithms (GA). But GA, though successfully applied in other fields of engineering, still waits to be applied broadly in architectural design. A main problem lies in defining function in architecture. It is much harder to define the function of a building than that of a machine. Without specifying the function of the artifact, the fitness function of the design variants participating in the survival game of artificial evolution remains undetermined. It is impossible to fully specify the fitness function of architecture. The approach presented is one of circumventing a full specification through dividing labor between the GA software and its user. The fitness function of architectural ground plans is typically defined in terms only of the proportions of the room to be accommodated and certain topological relations between them. The rest is left to the human designer who interactively intervenes in the evolution game as displayed on the screen.

summary	The paper presents a system that supports architectural floor plan design interactively. The method of problem solving implemented is a combination of an evolutionary strategy (ES) and a genetic algorithm (GA). The problem to be solved consists of fitting a number of rooms (n) into an outline by observing functional requirements. The rooms themselves are specified concerning size, function and preferred proportion. The functional requirements entering the fitness functions are expressed in terms of the proportions of the rooms and the neighbourhood relations between them. The system is designed to deal with one of the core problems of computer supported creativity in architecture. For architecture, form not only, but also function is relevant. Without specifying the function that a piece of architecture is supposed to fulfil, it is hard to support its design by computerised methods of problem solving and optimisation. In architecture, however, function relates to comfort, easiness of use, and aesthetics as well. Since it is extraordinary hard, if not impossible, to operationalise aesthetics, computer aided support of creative architectural design is still in its infancy.

title	Robot assembly system for computer-integrated construction
source	Automation in Construction 9 (5-6) (2000) pp. 479-487
summary	The construction industry demands a productivity increase that cannot be attained by means of traditional methods for masonry that have already reached their system limits and cannot contribute to further effectiveness. Further rationalisation can only be achieved by the reduction of labour and construction times. Therefore, a certain innovative leap is required by a system approach that combines the already existing construction technologies with new information, automation and robot technologies. An integrated automation system has been developed in the European ESPRIT III Robot Assembly System for Computer Integrated Construction (ROCCO) Project. Industrial partners and research centres from Germany, Spain and Belgium that are linked to the construction industry and robotics have formed the consortium. Block assembly tasks are performed by means of two robotics systems. One of the many challenges of these systems is related with the development of the control approach of large-range robots with hydraulic actuators. Conventional control strategies, based on PID or PD controllers and linear models, are unsuitable and prove completely inefficient for these robots. New control methods are necessary in order to achieve high performance with a reasonable time-consuming algorithm, useful in a real time control system. The most significant aspects related to the development of these robotic systems and their control systems are presented in this paper.

title	Enabling 3D Visualization of Simulated Construction Operations
source	Virginia Polytechnic Institute and State University
summary	Simulation modeling and visualization can substantially help in designing complex construction operations and in making optimal decisions where traditional methods prove ineffective or are unfeasible. However, there has been limited use of simulation in planning construction operations due to the unavailability of appropriate visual communication tools that can provide users with a more realistic and comprehensible feedback from simulation analyses. Visualizing simulated construction operations in 3D can significantly help in establishing the credibility of simulation models. In addition, 3D visualization can provide valuable insight into the subtleties of construction operations that are otherwise non-quantifiable and presentable. New software development technologies emerge at incredible rates that allow engineers and scientists to create novel, domain-specific applications. This study capitalized on a computer graphics technology based on the concept of the Scene Graph to design and implement a general-purpose 3D Visualization System that is Simulation and CAD-software independent. This system, the Dynamic Construction Visualizer, enables realistic visualization of modeled construction operations and the resulting products in 3D and can be used in conjunction with a wide variety of simulation tools. This thesis describes the Dynamic Construction Visualizer as well as the Scene Graph architecture and the Frame Updating algorithms used in its design.

title	A model for automation of infrastructure maintenance using representational forms
source	Automation in Construction 10 (1) (2000) pp. 57-68
summary	This paper proposes a model for the application of imaging to the automation of infrastructure maintenance. The model incorporates: (a) a domain structure, (b) human-machine interaction, (c) processes including machine vision, sensor data fusion, automated task planning, and control loops, and (d) graphical representation and visualization. In this paper, results are presented for automated crack and joint sealing, focusing on the development and use of a line snapping machine vision algorithm. It is concluded that the algorithm should be broadly applicable to applications in pavements, buildings, bridges, storage tanks, tunnels and utility pipes. The model can provide context and structure for development of new algorithms.

title	Constraint-based support for negotiation in collaborative design
source	Artificial Intelligence in Engineering, Vol: 14, Issue: 3, pp. 261-280.
summary	Solution spaces are proposed, instead of single solutions only, to support collaborative tasks during design and construction. Currently, partners involved in construction projects typically assign single values for sub-sets of variables and then proceed, often after tedious negotiations with other partners, to integrate these partial solutions into more complete project descriptions. We suggest the use of constraint solving to express possibly large families of acceptable solutions in order to improve the negotiation process in two ways. On one hand, con ict detection can be performed in an automated manner. Through the constraints collaborators impose, they de ne large unfeasible areas where no solution to the problem at hand can be expected. An emty intersectidon of the solution spaces can thus point at a con ict of design goals of the di erent collaborators at an early stage of the design process. On the other hand, important decision support during negotiation is provided. When a solution space is found, collaborators know during negotiation that they are negotiating about feasible solutions. Negotiation is no longer a means to nd a solution to the problem but it takes place in order to nd a good or the best solution. Since the consistency of the design remains ensured, collaborators are expected to be less restrictive towards innovative ideas during negotiation. Moreover, constraint techniques using explicit representations of solution spaces can provide tools to visualize trade-o s and illustrate the impact of certain decisions on other parameters. Thus decision-making is improved during the negotiation. New algorithms have been developed at EPFL for solving multi-dimensional nonlinear inequality constraints on continuous variables. Together with intuitive user interfaces such constraint-based support leads to better change management and easier implementation of least commitment decision strategies. It is expected that the results of this research can improve both the e ciency of negotiation processes and the quality of the achieved results.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 459-465
summary	This paper introduces the Virtual Design Studio (VDS), an internet based design studio environment established by ifib. VDS transfers lessons learned through research projects in the field of Computer Supported Co-operative Work (CSCW) being carried out at ifib into design education. By training for interdisciplinary co-operation within the design process, the students will become better prepared for the flexibility and co-operability required in planning situations. Increasing the communication and co-operation in the planning process can be achieved through the implementation of IT based virtual workspaces. In the design studio setting, this is done through the use of available internet software and technologies. The methodology of the VDS is briefly described including specific assignments intended to focus student investigations into specific areas including the representation of their work using the world wide web. The pedagogical expectations are discussed and anecdotal evidence precedes an general evaluation of the teaching method. The authors postulate that one of the unintended by-products of the studio is the evolution of an effective use of interactivity in the presentation of design concepts, ideas and solutions. A handful of student work is presented to describe the different approaches taken in using the world wide web (WWW) to display project work. A description of the local evolution (VDS specific) of graphical methods and technologies is followed by a comparison with those used in traditional settings. Representation is discussed with focus on the ability of the WWW to replace, augment or corrupt other methods of presentation. The interactive nature of web based presentations induces alterations to the narration of architectural work and can enhance the spatial perception of design space. Space Perception can be enabled through geometrically true VRML representations, the inclusion of auditory sensations, the abstraction of representation through the use of advertising techniques as well as the introduction of non-linear narrative concepts. Examples used by students are shown. A critical assessment of these new representational methods and the place of current new media within the context of architectural representation is discussed.

summary	The building sector is entering a new era. Developments in information and communication technology have an impact throughout the entire life cycle of a building, not only from a process and technical point of view but also from a creative design point of view. As a result of developments of advanced modeling software for architectural design, the gap between what the architect can envision and what the building technician or product architect can materialize is enlarging. Internet technology has already started to provide a closer link between the participants in the building process, their activities, knowledge, and information. Concurrent and collaborative engineering will be the future of building practice in respect to efficiency and quality improvement of this sector. The nature of the building process is complex, not only from a communication point of view, but also from the information of the number of participants, the spatial organization and the infrastructure etc. In the near future, soft computing techniques such as artificial neural networks, fuzzy logic, and genetic algorithms will make contributions to the problem solving aspects of the complex design process. This paper provides an overview of these and other future developments of information and communication technology (ICT) within the building sector.

title	Music Composition with Interactive Evolutionary Computation
source	International Conference on Generative Art
summary	Interactive Evolutionary Computation (IEC), i.e., Evolutionary Computation whose fitness function is provided by a user his/herself, has been applied to esthetic areas, such as art, design and music. We cannot necessarily define fitness functions explicitly in these areas. With IEC, however, we can embed the user's implicit preference into the optimization system. This paper describes a new approach to music composition, more precisely the composition of rhythms, by means of IEC. The main feature of our method is to combine Genetic Algorithms (GA) and Genetic Programming (GP). In our system, GA individuals represent short pieces of rhythmic patterns, while GP individuals express how these patterns are arranged in terms of their functions. Both populations are evolved interactively through the user's evaluation. The integration of interactive GA and GP makes it possible to search for musical structures effectively in the vast search space. In this paper, we show how successfully our proposed method can generate attractive musical rhythms. The effectiveness of our system is demonstrated by the evolved rhythm phrases, which are available from our web site as sound files.

title	Digital Architecture in CAD studio and Internet-based competition

summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	Data Mining - Practical Machine Learning Tools and Techniques with JAVA Implementations
source	Morgan Kaufmann
summary	Witten and Frank's textbook was one of two books that I used for a data mining class in the Fall of 2001. The book covers all major methods of data mining that produce a knowledge representation as output. Knowledge representation is hereby understood as a representation that can be studied, understood, and interpreted by human beings, at least in principle. Thus, neural networks and genetic algorithms are excluded from the topics of this textbook. We need to say "can be understood in principle" because a large decision tree or a large rule set may be as hard to interpret as a neural network. The book first develops the basic machine learning and data mining methods. These include decision trees, classification and association rules, support vector machines, instance-based learning, Naive Bayes classifiers, clustering, and numeric prediction based on linear regression, regression trees, and model trees. It then goes deeper into evaluation and implementation issues. Next it moves on to deeper coverage of issues such as attribute selection, discretization, data cleansing, and combinations of multiple models (bagging, boosting, and stacking). The final chapter deals with advanced topics such as visual machine learning, text mining, and Web mining.

title	TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source	International Conference on Generative Art
summary	TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.
