Polyphonic Instrument Detection

This project was a collaboration with Takahiko Tsuchiya.

A system was developed to perform instrument detection using Non-Negative Matrix Factorization and Support Vector Machine in polyphonic music. I primarily worked on NMF and SVM aspect of the project and the evaluation scheme. Takahiko worked primarily on time-domain / auditory-based polyphonic pitch detection (stage 1).
