API Reference

Two versions of the EM algorithms exist : batch and online :

• The batch version takes all the point at the same time, using more CPU and memory but may lead to more accurate results.
• The online version takes the points w by w. In this way the program uses less CPU and memory, but there may be a loss of accuracy.

Batch versions of the algorithm

Four different algorithms have been developped in batch: K-means, GMM, VBGMM and DPGMM.

Kmeans

Gaussian Mixture Model (GMM)

Variational Gaussian Mixture Model (VBGMM)

Dirichlet Process Gaussian Mixture Model (DPGMM)

Online versions of the algorithm

Only two algorithms have been developped in batch: K-means and GMM.

Kmeans
