Java Demo of EM algorithm

Posted on January 6, 2005

I found this interesting demonstration of the EM algorithm for fitting mixture models to data linked from Paul Lamere’s blog Duke Listens!. As paul writes:

Many pattern classification problems (including speech recognition and music classification) are solved by using a set of probability distributions called mixture models to represent a single statistical distribution. The EM algorithm is often used to determine the set of distributions given the raw data and the desired number of distributions. S. Akaho has a Java applet that demonstrates how the EM algorithm works. First you draw your data, next you tell it how many probability distributions you want, and then you tell it to go and it will use the EM algorithm to calculate the best sets of distributions.

    You will have to follow up with the author at http://www.neurosci.aist.go.jp/~akaho/MixtureEM.html to obtain any source code that might be available.
