Gaussian Mixture node
A Gaussian Mixture© model is a probabilistic model that assumes all the data points are generated from a mixture of a finite number of Gaussian distributions with unknown parameters.
One can think of mixture models as generalizing k-means clustering to incorporate information about the covariance structure of the data as well as the centers of the latent Gaussians.1
The Gaussian Mixture node in Watson Studio exposes the core features and commonly used parameters of the Gaussian Mixture library. The node is implemented in Python.
