On May 12, 2011, I defended my dissertation entitled “Sparse and Nonnegative Factorizations for Music Understanding“. Matrix factorizations have become popular for performing music transcription and source separation. However, the basic factorization algorithms have trouble decomposing highly polyphonic music. In this dissertation, I proposed factorization methods that are specifically suited for analyzing musical signals, including a method that can efficiently use a musical spectral dictionary if one already exists.

On May 20, I graduated.

On May 28, I boarded a one-way flight to San Francisco. I left my 1999 Saturn SC2 in New Jersey, shipped nineteen boxes to San Francisco, and sold everything else.

On June 6, I began work at Imagine Research, Inc., in San Francisco. We build software that understands sound. My position is sponsored by a National Science Foundation (NSF) Postdoctoral Research Fellowship and administered by the American Society for Engineering Education (ASEE).

On June 14, I signed a lease for my new apartment. After two weeks of apartment hunting, I found a wonderful place in the Sunset district of San Francisco for only $800 per month with views of Golden Gate Park right across the street.

From June 27 to July 1, I attended and helped instruct a workshop on music information retrieval at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford. We all had a great time talking about music, signal processing, and machine learning.
