- Application of computational intelligence to engineeringPublication . Marques, Viriato M.; Roseiro, Luís; Reis, Cecília; Machado, J. A. TenreiroComputational Intelligence (CI) includes four main areas: Evolutionary Computation (genetic algorithms and genetic programming), Swarm Intelligence, Fuzzy Systems and Neural Networks. This article shows how CI techniques overpass the strict limits of Artificial Intelligence field and can help solving real problems from distinct engineering areas: Mechanical, Computer Science and Electrical Engineering.
- Computational intelligence techniques in engineeringPublication . Marques, Viriato M.; Reis, Cecília; Roseiro, Luís; Tenreiro Machado, J. A.This article shows how CI techniques overpass the strict limits of Artificial Intelligence (AI) field and can help solving real problems from distinct engineering areas: Mechanical, Computer Science and Electrical Engineering. An introduction to each of the CI main areas is made and three systems are briefly described. The results are, in each case, very promising
- Evolutionary perspectives in computer musicPublication . Reis, Cecília; Marques, Viriato M.; Tenreiro Machado, J. A.This paper presents a brief overview of music evolution - western and non-western music - from its genesis to serialism and the Darmstadt school. Some mathematical aspects of music are then presented and confronted with music as a form of art. Some questions follow: are these two (very) distinct aspects compatible? Can computers be of real help in automatic composition? Evolutionaty Algorithms (EAs) - Genetic Algorithms (GAs), Genetic Programming (GP), Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) - are then introduced and some results of GAs and GPs application to music generation are analysed. Variable fitness functions and PSO application seems a promising way to explore. However, what output should be envisaged? Should we expect that computer music sounds as human music, or should we look for a totally different way to explore and listen? How far can go computer creativity and in what direction?
- Interactive Evolutionary Computation in MusicPublication . Marques, Viriato M.; Reis, Cecília; Tenreiro Machado, J. A.This paper presents a simple approach for implementing Interactive Evolutionary Computation (IEC) - a paradigm in which humans directly intervene in fitness evaluation - in the field of musical melody generation. Music is an art and, as all kinds of art, it involves creativity. However, creativity is still a human capability. A Genetic Algorithm (GA) based application has been developed and tested. The initial population was generated according to Zipf’s Law. Simple melodies, obtained in a few iterations, can be quickly transformed into complete and interesting songs.
- Music and evolutionary computationPublication . Reis, Cecília; Marques, Viriato M.; Machado, J. A. TenreiroThis paper presents a brief history of the western music: from its genesis to serialism and the Darmstadt school. Also some mathematical aspects of music are then presented and confronted with music as a form of art. The question is, are these two distinct aspects compatible? Can computers be of real help in automatic composition? The more appealing algorithmic approach is evolutionary computation as it offers creativity potential. Therefore, the Evolutionary Algorithms are then introduced and some results of GAs and GPs application to music generation are analysed.
- A Review on Humanized Computational IntelligencePublication . Reis, Cecília; Marques, Viriato M.; Tenreiro Machado, J. A.Computational Intelligence (CI) has three main foundations: Neural Networks, Evolutionary Computation (EC) and Fuzzy Systems (FS). Collaborating systems based on these models have been built and installed in prototypes and successful consumer products. However, creativity still is a main human task, in great part due to the presence of subjective values and psychological / emotional responses in the evaluation of the created objects. In this context the Interactive Evolutionary Computation (IEC), a paradigm in which humans directly intervene in fitness evaluation, is a new direction for CI research. Art, education and engineering are some examples of IEC application domains.
