SYNOPSIS¶

Namespaces¶

mlpack Linear algebra utility functions, generally performed on matrices or vectors. mlpack::gmm Gaussian Mixture Models.

Functions¶

double mlpack::gmm::phi (const double x, const double mean, const double var) Calculates the univariate Gaussian probability density function. double mlpack::gmm::phi (const arma::vec &x, const arma::vec &mean, const arma::mat &cov) Calculates the multivariate Gaussian probability density function. double mlpack::gmm::phi (const arma::vec &x, const arma::vec &mean, const arma::mat &cov, const std::vector< arma::mat > &d_cov, arma::vec &g_mean, arma::vec &g_cov) Calculates the multivariate Gaussian probability density function and also the gradients with respect to the mean and the variance. void mlpack::gmm::phi (const arma::mat &x, const arma::vec &mean, const arma::mat &cov, arma::vec &probabilities) Calculates the multivariate Gaussian probability density function for each data point (column) in the given matrix, with respect to the given mean and variance.
