gmm_probability: GMM Probability Calculator
In mlpack: 'Rcpp' Integration for the 'mlpack' Library

Description Usage Arguments Details Value Author(s) Examples

A probability calculator for GMMs. Given a pre-trained GMM and a set of points, this can compute the probability that each point is from the given GMM.

1	gmm_probability(input, input_model, verbose = FALSE)

`input`	Input matrix to calculate probabilities of (numeric matrix).
`input_model`	Input GMM to use as model (GMM).
`verbose`	Display informational messages and the full list of parameters and timers at the end of execution. Default value "FALSE" (logical).

This program calculates the probability that given points came from a given GMM (that is, P(X | gmm)). The GMM is specified with the "input_model" parameter, and the points are specified with the "input" parameter. The output probabilities may be saved via the "output" output parameter.

A list with several components:

output

Matrix to store calculated probabilities in (numeric matrix).

# So, for example, to calculate the probabilities of each point in "points"
# coming from the pre-trained GMM "gmm", while storing those probabilities in
# "probs", the following command could be used:

## Not run: 
output <- gmm_probability(input_model=gmm, input=points)
probs <- output$output

## End(Not run)
