Effects of Time and Frequency Resolution on Nonnegative Matrix Factorization

In this paper, we present the comparison of note events extraction using Nonnegative Matrix Factorization (NMF) with input from a classic Fourier Transform (FT) and with input from an improved time resolution FT. In order to improve time resolution, FT sample window length must be increased. As the...
