GMMBAYES - Gaussian Mixture Model Methods
Goal of this project is to study existing and develop new methods for learning Gaussian mixture models. Furthermore, class conditional probability densities constructed by Gaussian mixture models and their usage in classification are considered during the project.
The main practical goal of this project is to implement efficient classification functionality (training and classification) based on statistical theory (e.g., Bayesian inference) and Gaussian mixture model probability densities. The ML parameter estimation will be extensively studied.

Erratum: The document contains an incorrect formula for computing complex Gaussian PDF values. The correct formula is:
1/(piD|S|) e -(x-u)*S-1(x-u)
