A. Kaliakatsos–Papakostas %A M. G. Epitropakis %A A. Floros %A M. N. Vrahatis %E Penousal Machado %E Juan Romero %E Adrian Carballal %X The efficient specification of aesthetic measures for music as a part of modelling human conception of sound is a challenging task and has motivated several research works. It is not only targeted to the creation of automatic music composers and raters, but also reinforces the research for a deeper understanding of human noesis. The aim of this work is twofold: first, it proposes an Interactive Evolution system that uses Genetic Programming to evolve simple 8–bit melodies. The results obtained by subjective tests indicate that evolution is driven towards more user–preferable sounds. In turn, by monitoring features of the melodies in different evolution stages, indications are provided that some sound features may subsume information about aesthetic criteria. The results are promising and signify that further study of aesthetic preference through Interactive Evolution may accelerate the progress towards defining aesthetic measures for sound and music. %B Evolutionary and Biologically Inspired Music, Sound, Art and Design %S Lecture Notes in Computer Science %I Springer Berlin / Heidelberg %V 7247 %P 141-152 %@ 978-3-642-29141-8 %G eng %R 10.1007/978-3-642-29142-5_13 %0 Book Section %B Artificial Intelligence: Theories and Applications %D 2012 %T Tracking Differential Evolution Algorithms: An Adaptive Approach through Multinomial Distribution Tracking with Exponential Forgetting %A M. G. Epitropakis %A D. K. Tasoulis %A N. G. Pavlidis %A V. P. Plagianakos %A M. N. Vrahatis %E Ilias Maglogiannis %E Vassilis P. Plagianakos %E Ioannis Vlahavas %X Several Differential Evolution variants with modified search dynamics have been recently proposed, to improve the performance of the method. This work borrows ideas from adaptive filter theory to develop an “online” algorithmic adaptation framework. The proposed framework is based on tracking the parameters of a multinomial distribution to reflect changes in the evolutionary process. As such, we design a multinomial distribution tracker to capture the successful evolution movements of three Differential Evolution algorithms, in an attempt to aggregate their characteristics and their search dynamics. Experimental results on ten benchmark functions and comparisons with five state-of-the-art algorithms indicate that the proposed framework is competitive and very promising. %B Artificial Intelligence: Theories and Applications %S Lecture Notes in Computer Science %I Springer Berlin / Heidelberg %V 7297 %P 214-222 %@ 978-3-642-30447-7 %G eng %R 10.1007/978-3-642-30448-4_27 %0 Book Section %B Mathematics and Computation in Music %D 2011 %T Feature Extraction Using Pitch Class Profile Information Entropy %A M. A. Kaliakatsos-Papakostas %A M. G. Epitropakis %A M. N. Vrahatis %E Agon, Carlos %E Andreatta, Moreno %E Assayag, Gérard %E Amiot, Emmanuel %E Bresson, Jean %E Mandereau, John %X Computer aided musical analysis has led a research stream to explore the description of an entire musical piece by a single value. Combinations of such values, often called global features, have been used for several identification tasks on pieces with symbolic music representation. In this work we extend some ideas that estimate information entropy of sections of musical pieces, to utilize the Pitch Class Profile information entropy for global feature extraction. Two approaches are proposed and tested, the first approach considers musical sections as overlapping sliding onset windows, while the second one as non-overlapping fixed-length time windows. %B Mathematics and Computation in Music %S Lecture Notes in Computer Science %I Springer Berlin / Heidelberg %V 6726 %P 354-357 %G eng %U http://dx.doi.org/10.1007/978-3-642-21590-2_32 %R 10.1007/978-3-642-21590-2_32 %0 Conference Paper %B Applications of Evolutionary Computation %D 2010 %T Musical Composer Identification through Probabilistic and Feedforward Neural Networks %A M.

Here, we examine the information capacity of the Dodecaphonic Trace Vector for composer classification and identification. To this end, we utilize Probabilistic Neural Networks for the construction of a similarity matrix of different composers and analyze the Dodecaphonic Trace Vector’s ability to identify a composer through trained Feedforward Neural Networks. The training procedure is based on classical gradient-based methods as well as on the Differential Evolution algorithm. An experimental analysis on the pieces of seven classical composers is presented to gain insight about the most important strengths and weaknesses of the aforementioned approach. %B Applications of Evolutionary Computation %I Springer Berlin / Heidelberg %G eng %R 10.1007/978-3-642-12242-2\_42
