gmm_probability | R Documentation |

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.

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)
