Hi, cjain, you have function call mu in path. It is your problem to solve, not mine.

04 May 2013 kmeans clustering Fully vectorized kmeans algorithm. Fast yet simple (10 lines) Author: Mo Chen Ramani

please help me in Em estimator for parameter estimation
03 May 2013 kmeans clustering Fully vectorized kmeans algorithm. Fast yet simple (10 lines) Author: Mo Chen Zoé

Seems to be broken in R2013a due too a column/row vector mix-up. As a quick workaround I have added

label = reshape(label, length(label), 1);

after line 15 in litekmeans.m.

15 Apr 2013 Variational Bayesian Inference for Gaussian Mixture Model Variational Bayes method (mean field) for GMM can auto determine the number of components Author: Mo Chen Paul

Easy to use and quick for my data (~4000 pts, yielding ~20 clusters).

That having been said, is there any chance of getting more documentation on the outputs?

I need to take the identified clusters and use the model to classify future data. I've read and understood Bishop, but it is still difficult to reverse engineer the code (terse the variable names) to actually use the identified model.
