Variational Bayesian inference for unsupervised clustering, mixture of independent Gaussians
vimixIndGauss(X, K, prior, init = "kmeans", tol = 1e-19, maxiter = 2000, verbose = F)
NxD data matrix.
(Maximum) number of clusters.
Prior parameters (optional).
Initialisation method (optional). If it is a vector, it is interpreted as the vector of initial cluster allocations. If it is a string, it is interpreted as the name of the clustering algorithm used for the initialisation (only "kmeans" and "random") available at the moment).
Tolerance on lower bound. Default is 10e-20.
Maximum number of iterations of the VB algorithm. Default is 2000.
Boolean flag which, if TRUE, prints the iteration numbers. Default is FALSE.
A list containing L, the lower bound at each step of the algorithm, label, a vector containing the cluster labels, model, a list containing the trained model structure.
