| 24 </h2> | |
| 25 This script demonstrates the use of the EM algorithm to fit a mixture | |
| 26 of Gaussians to a set of data using maximum likelihood. A colour | |
| 27 coding scheme is used to illustrate the evaluation of the posterior | |
| 28 probabilities in the E-step of the EM algorithm. | |
