Artificial Musical Compositions Using Deep Belief Nets and Genetic Algorithms
AuthorAs a graduation project, I've designed an innovative method for composing music using a hybrid structure. The fitness function of a genetic algorithm is constructed from a k-means filter of an unsupervised neural network output. This structure allows for the emulation of human behaviors without introducing any bias.
