Generative Spectrogram Factorization Models for Polyphonic Piano Transcription

Abstract

We introduce a framework for probabilistic generative models of time-frequency coefficients of audio signals, using a matrix factorization parametrization to jointly model spectral characteristics such as harmonicity and temporal activations and excitations. The models represent the observed data as the superposition of statistically independent sources… (More)
