nn_fac

pip install nn-fac


Toolbox of nonnegative factorization techniques, for both matrices (NMF) and tensors (NN-CP, NN-PARAFAC2 and NTD).
These decompositions are computed by solving NNLS (NonNegative Least Squares) problems on every factor when optimizing with respect to the Euclidean norm, or with Multiplicative Updates subject to each factor when optimizing the Beta-divergences.

Note: the techniques of this toolbox are also integrated to the tensorly toolbox thanks to my colleague Caglayan Tuna! :)

barmuscomp

pip install barmuscomp


Code related to linear and nonlinear compression schemes, applied to music songs. The compressed representations are then used to infer the music structure.
See our article "Barwise Compression Schemes for Audio-Based Music Structure Analysis." for more details.

musiconpolytopes

pip install musiconpolytopes


Code associated with the polytopical framework, used as a structural segmentation criterion for symbolic music.
See the preprint "Polytopic Analysis of Music" for more details.

Deprecated toolboxes

(Sometimes refered to in articles)

BarwiseMusicCompression


Code related to linear and non-linear barwise music compression, then used for music segmentation.
Associated to the paper "Barwise Compression Schemes for Audio-Based Music Structure Analysis.", but replaced by the toolbox barmuscomp since.

Axel Marmoret, Jérémy Cohen, Frédéric Bimbot. BarwiseMusicCompression. 2022.

MusicAE


Code related to single-song autoencoding, then used for music segmentation. This code is actually deprecated, because contained and enhanced in the larger barmuscomp toolbox.
Associated to the preprint "Exploring single-song autoencoding schemes for audio-based music structure analysis".

Axel Marmoret, Jérémy Cohen, Frédéric Bimbot. MusicAE. 2021.

MusicNTD


Code related to the pre-processing of data for using the NTD. This code is actually deprecated, because contained and enhanced in the larger barmuscomp toolbox.
Associated to the article "Uncovering Audio Patterns in Music with Nonnegative Tucker Decomposition for Structural Segmentation".
