Discovering Tonal Profiles with Latent Dirichlet Allocation [PDF]
Music & Science, 2021 Music analysis, in particular harmonic analysis, is concerned with the way pitches are organized in pieces of music, and a range of empirical applications have been developed, for example, for chord recognition or key finding. Naturally, these approaches

A Spectral Algorithm for Latent Dirichlet Allocation [PDF]
Algorithmica, 2012 The problem of topic modeling can be seen as a generalization of the clustering problem, in that it posits that observations are generated due to multiple latent factors (e.g., the words in each document are generated as a mixture of several active ...
