mergeSubcascades {ORION}

Merge Subcascades

Description

mergeSubcascades adds the cascades from subcascades2 to the subcascades1, that have not been part of subcascades1.

Usage

mergeSubcascades(subcascades1 = NULL, subcascades2 = NULL)

Arguments

subcascades1

A Subcascades object as it is returned by subcascades-function. The Subcascades object is made up of a list of matrices. Each matrix comprises the evaluation results of cascades of a specific length. The rownames show the class order and the entries the sensitivity for each position of the cascade.

subcascades2

A Subcascades object like subcascades1

Value

A Subcascades object comprising the evaluated cascades and their performances. The Subcascades object is made up of a list of matrices. Each matrix comprises the evaluation results of cascades of a specific length and is sorted row-wise according to the achieved minimal classwise sensitivities of the cascades (decreasing). The rownames show the class order by a character string of type '1>2>3' and the entries the sensitivity for each position of the cascade.

Examples

library(TunePareto)
data(esl)
data = esl$data
labels = esl$labels
foldList = generateCVRuns(labels  = labels,
                          ntimes      = 2,
                          nfold       = 2,
                          leaveOneOut = FALSE,
                          stratified  = TRUE)
predMap = predictionMap(data, labels, foldList = foldList, 
                       classifier = tunePareto.svm(), kernel='linear')

# make two Subcascades objects
subc1 = subcascades(predMap, size = c(3,4), thresh = 0.6)
subc2 = subcascades(predMap, size = c(4), thresh = 0.5)
# add the cascades of subcascades2 to subcascades1
mergeSubcascades(subc1, subc2)
