maximisation_uv

data

(matrix): The probability weight matrix.

weights

(vector): The vector of sigma (standard-deviations).

sigma

prior

(numeric): The number of clusters.

num_clusters

(numeric): The total number of observations in the data.

num_data

Calculates meu, sigma and prior based on the updated probability weight matrix.

Implements the Improved Expectation Maximisation EM* and the traditional EM algorithm for clustering
big data (gaussian mixture models for both multivariate and univariate datasets). This version
implements the faster alternative-EM* that expedites convergence via structure based data segregation.
The implementation supports both random and K-means++ based initialization. Reference: Parichit Sharma,
