WebJan 1, 2016 · The DPGMM is a Bayesian non-parametric model that automatically detects the optimal number of classes given a set of data. We make use of this property and run an initial clustering on standard feature vectors to get a set of class labels and the hypothesized class membership of every speech frame. WebSep 19, 2016 · I expected scikit-learn's DP-GMM to allow for online update of cluster assignments given new data, but sklearn's implementation of DP-GMM only has a fit method. My understanding of variational inference is yet unclear and I think that the inability of doing online update of cluster assignments is particular of sklearn's implementation, …
