mnist_weights_gmm.mat vs. mnist_gene.mat

From what I know, the gmm network parameters (theta, lambda & u) are the results of the tensors (u_p, lambda_p & theta_p) after training. However, I noticed that the gmm network parameters in mnist_weights_gmm.mat and those in mnist_gene.mat have different values. Do anyone know where is the source for these two trained gmm parameter come from? Thank you
