Definition of the [ClusterDiagGaussian] class

Description

This class defines a diagonal Gaussian mixture Model.

Details

This class inherits from the [IClusterModel] class. A diagonal gaussian model is a mixture model of the form:

f({x}|\boldsymbol{θ}) =∑_{k=1}^K p_k ∏_{j=1}^d φ(x_j;μ_{jk},σ^2_{jk}) \quad x \in {R}^d.

Some constraints can be added to the variances in order to reduce the number of parameters.
