gmm_generate: GMM Sample Generator

In mlpack: 'Rcpp' Integration for the 'mlpack' Library

GMM Sample Generator

Description

A sample generator for pre-trained GMMs. Given a pre-trained GMM, this can sample new points randomly from that distribution.

Usage

gmm_generate(
  input_model,
  samples,
  seed = NA,
  verbose = getOption("mlpack.verbose", FALSE)
)

Arguments

input_model	Input GMM model to generate samples from (GMM).
samples	Number of samples to generate (integer).
seed	Random seed. If 0, 'std::time(NULL)' is used. Default value "0" (integer).
verbose	Display informational messages and the full list of parameters and timers at the end of execution. Default value "getOption("mlpack.verbose", FALSE)" (logical).

Details

This program is able to generate samples from a pre-trained GMM (use gmm_train to train a GMM). The pre-trained GMM must be specified with the "input_model" parameter. The number of samples to generate is specified by the "samples" parameter. Output samples may be saved with the "output" output parameter.

Value

A list with several components:

output

Matrix to save output samples in (numeric matrix).

Examples

# The following command can be used to generate 100 samples from the
# pre-trained GMM "gmm" and store those generated samples in "samples":

## Not run: 
output <- gmm_generate(input_model=gmm, samples=100)
samples <- output$output

## End(Not run)
