public class SequentialTrainingSelector
extends TrainingSelector

Selects groups of fragments into training / test groups simply by concatonating all the files together from some random start point.

Method Detail

getTotalSections

int getTotalSections(int iSpecies,
                     int sectionLength)

Description copied from class: TrainingSelector

Get the total number of training + test sections, each consisting of sectionLength fragments

Specified by:

getTotalSections in class TrainingSelector

Parameters:

iSpecies - species index in training set

sectionLength - length of each training or test section

Returns:

number of complete sections

createSections

public int[] createSections(int iSpecies,
                            double trainingFraction,
                            int sectionLength)

Description copied from class: TrainingSelector

Tell the training selector to create a new (hopefully randomised) set of training and test data for a species.

It does not actually have to create the data sets at the moment - if it want's to save memory it can set up appropriate data structures to define what the sets are and then create them when they are asked for later. Whether or not this is possible may depend on the type of randomisation and grouping employed in the concrete class.

Specified by:

createSections in class TrainingSelector

trainingFraction - fraction of data to be used in training (usually 2/3)

Returns:

a two element array giving the number of test and the number of training sections

createTrainingSection

private int[] createTrainingSection(TrainingDataGroup trainingDataGroup,
                                    double trainingFraction,
                                    int sectionLength)

                       TrainingDataGroup trainingDataGroup,
                       int nStores,
                       int sectionLength,
                       int iContour)

getFragmentStore

public FragmentStore getFragmentStore(boolean training,
                                      int iFragmentGroup)

Specified by:
