MEL-CEPSTRUM
4.0
Implements a mel-cepstrum front end for a recognise. In sound processing , the mel-frequency cepstrum ( MFC ) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients ( MFCCs ) are coefficients that collectively make up an MF

Entropy of discrete and sampled continuous distrib
no vote
Calculates the entropy of discrete and sampled continuous distributions. Differential entropy (also referred to as continuous entropy ) is a concept in information theory that extends the idea of (Shannon) entropy , a measure of average surprisal of a random variable , to continuous probability distributions .
