    """ Mixture Density Network layer

    The input maps to the parameters of a Mixture of Gaussians (MoG) probability
    distribution, where each Gaussian has out_dim dimensions and diagonal covariance.
    If dim_wise is True, features for each dimension are modeld by independent 1-D GMMs
    instead of modeling jointly. This would workaround training difficulty
    especially for high dimensional data.
