The question of whether piano timbre can be changed according to a pianist’s intent had not been answered in over 100 years.
Using proprietary non-contact sensors capable of measuring key positions at 1000 fps, we measured key movements when professional pianists played using various timbres.
Data science and psychophysical experiments revealed that timbres intended by pianists were perceived by listeners, regardless of whether they had any piano playing experience.
Sounds produced by keystrokes differing only in specific key movement features were perceived as distinct timbres, thereby identifying a causal relationship between key movement and timbre.
The University of Osaka researchers developed a reinforcement learning framework that lets dialogue systems efficiently learn new words while asking fewer questions. This approach enhances user experience and enables future systems to naturally acquire family-specific nicknames and expressions, becoming more familiar companions in everyday life.
Research has opened the door for coastal wetland restoration projects to potentially earn tradeable biodiversity certificates.
