Details

This class inherits from the [IClusterModel] class. A diagonal gaussian model is a mixture model of the form: $$ f({x}|\boldsymbol{\theta}) =\sum_{k=1}^K p_k \prod_{j=1}^d \phi(x_j;\mu_{jk},\sigma^2_{jk}) \quad x \in {R}^d. $$ Some constraints can be added to the variances in order to reduce the number of parameters.
