Together with Dr. Kat Agres (NUS, Singapore) and Prof. Louis Bigo (University of Lille, France), I recently explored how harmonic structure influences altered states in uplifting trance music. "The Impact of Musical Structure on Enjoyment and Absorptive Listening States in Trance Music" is available as a chapter in Music and Consciousness II, a book published by Ruth Herbert, Eric Clarke and David Clarke.
One of the most comprehensible machine learning instructors (Andrew Ng), has just released a new book. I found it an interesting and smooth read with focus on a few important issues that any data science / AI person will encounter. Highly recommend the read. More info on the book and how to get it.
