Outline of Final Research Achievements

We pioneered and fused the hierarchical mathematical models of music composition, performance and signal such as A: the signal layer including multipitch analysis of music signals, score following, signal conversion / processing / separation, sound source direction estimation, and music watermarking, B: the performance layer including performance analysis, rhythm estimation, automatic rendition, automatic accompaniment, automatic fingering decision and automatic jazz session, C: the score layer including harmony recognition based on mathematical formulation of music composition theory, automatic music composition from lyrics, automatic lyrics creation, automatic arrangement, automatic composition from images, and D: the common infrastructure including mathematical modeling that supports them, machine learning / optimization, and deep neural networks, focusing on problems between these layers.
