Detailed Description

Batch processing wrapper for MRMFeatureSelector.

This class enables iterative refinement of feature selection by applying MRMFeatureSelector multiple times with different parameter sets. Each iteration uses the output of the previous iteration as input, allowing for progressive filtering and optimization.

Usage

FeatureMap features, selected;
std::vector<MRMFeatureSelector::SelectorParameters> params_list;
 
// First pass: relaxed parameters
params_list.push_back(MRMFeatureSelector::SelectorParameters());
 
// Second pass: stricter parameters
MRMFeatureSelector::SelectorParameters strict;
strict.optimal_threshold = 0.8;
params_list.push_back(strict);
 
MRMBatchFeatureSelector::batchMRMFeaturesScore(features, selected, params_list);

Member Function Documentation

batchMRMFeatures()

static void batchMRMFeatures ( const MRMFeatureSelector &  feature_selector, const FeatureMap &  features, FeatureMap &  selected_features, const std::vector< MRMFeatureSelector::SelectorParameters > &  parameters  )

static

Calls feature_selector.selectMRMFeature() feeding it the parameters found in parameters. It calls said method parameters.size() times, using the result of each cycle as input for the next cycle.

Parameters

[in]	feature_selector	Base class for the feature selector to use
[in]	features	Input features
[out]	selected_features	Selected features
[in]	parameters	Vector of parameters for the multiple calls to the selector

batchMRMFeaturesQMIP()

static void batchMRMFeaturesQMIP ( const FeatureMap &  features, FeatureMap &  selected_features, const std::vector< MRMFeatureSelector::SelectorParameters > &  parameters  )

static

Calls batchMRMFeatures() using a MRMFeatureSelectorQMIP selector.

batchMRMFeaturesScore()

static void batchMRMFeaturesScore ( const FeatureMap &  features, FeatureMap &  selected_features, const std::vector< MRMFeatureSelector::SelectorParameters > &  parameters  )

static

Calls batchMRMFeatures() using a MRMFeatureSelectorScore selector.
