The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with reference to given cluster.

well done


i need to apply gmm for iris dataset and obtain 3 clusters.The final result should display the index of datapoints/ datapoints itself, in each of the clusters. i need help about this as soon as possible. please help


Can it be extended?

The code assumes isotropic Gaussians.


Great job :)

Although not documented the variable and function names made it easy (for me) to follow the code. I liked it ;)
