gmm_probability: GMM Probability Calculator

Description

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.

Usage

gmm_probability(input, input_model, verbose = FALSE)

Arguments

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).

Value

A list with several components:

output

Matrix to store calculated probabilities in (numeric matrix).

Details

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.

Examples

# NOT RUN {
# 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
# }
