Abstract:
This article presents a 2-phase computational learning model
and application. As a demonstration, a system has been built,
called CHIME for Computer Human Interacting Musical Entity. In
phase 1 of training, recurrent back-propagation trains the
machine to reproduce 3 jazz melodies. The recurrent network is
expanded and is further trained in phase 2 with a reinforcement
learning algorithm and a critique produced by a set of basic
rules for jazz improvisation. After each phase CHIME can
interactively improvise with a human in real time.
