Here are courses I taught Foundations of Nonmonotonic
Logics and a seminar on Topics on the border of
CS, Game Theory and Economics , Introduction
to Artificial Intelligence.
I am, with Dan and Ron
Gang, a founder of MusicGenome, Inc.(http://www.musicgenome.com), a company
that developed a proprietary technology for learning a userís taste, in music
and other entertainment fields. MusicGenomeís SmartDJ† uses this technology to provide a
radio that tunes up to the taste and the mood of the user. For a link to Danís
