Features_Preprocessing | R Documentation |
Features_Preprocess
does preprocessing, i.e. centering and rescaling using the internally separated training subdata.
Features_CorFilter
filters highly correlated features. Internally using parCor
to do parallelized calculation of a correlational matrix.
Features_FeatureSelect
selects important features. See also Features_Importance
.
inverseColOrderDFList
takes preprocessedDFList
and reverses the column order of the datatable.
Features_Preprocess(featureDFList, metadataDF, seedSet = 1:5) Features_CorFilter( preprocessedDFList, corThreshold = 0.75, coreN = parallel::detectCores(logical = F) ) Features_FeatureSelect( preprocessedDFList, featureN = 100, coreN = parallel::detectCores(logical = F) ) inverseColOrderDFList(preprocessedDFList)
