compute.external {StabPerf}R Documentation

Computes the samples for a given job.

Description

Either sampling features from a selector or errors from a feature-selection/classifier-combination

Usage

compute.external(parameters)

Arguments

parameters the job (a list of parameters) that should be computed with the elements offset, repeats, output, i (number of cv-fold), s (number of selector), selector, c (number of classifier), classifier, predictor

Details

Reads in the dataset from rawdata or the filesystem. If i > 0, cv-information is loaded from cvdata or the filesystem and afterwards selecting only the data not in the testings subset of the i-th fold. Then either features are sampled from a draw subset of the data (given a selector-job) or classifiers are trained and tested, using the previously sampled features/drawn indices (selector/classifier-job). Both is done repeats times, finally writing the sampled results to the corresponding checkpoint.

Value

Invisible NULL
