Threewell-establishedtechniques,namelycorrelationanalysis-basedfeatureselection(CFS),LASSOregres- sion, andmutualinformation(MI),areusedforFS.Databalancingisperformedusingbothoversamplingandundersampling techniques, includingthesyntheticminorityoversamplingtechnique(SMOTE),k-nearestneighboroversampling(KNNOR), and randomundersampling(RUS).Finally,hyperparameteroptimization(HPO)iscarriedoutbyadoptingvariousmethods including gridsearch,randomsearch,Bayesianoptimization,andsemi-automatictomaximizetheclassificationperfor- mance ofsevenrenownedMLalgorithms(logisticregression,decisiontree,randomforest,supportvectormachine,Naïve Bayes, k-nearestneighbor,andeXtremegradientboosting),andadeepneuralnetwork(DNN).Throughtheexperiments carried outonfourpubliclyavailabledatasets,includingWisconsindiagnosticbreastcancer(WDBC),Wisconsinbreast cancer dataset(WBCD),Wisconsinprognosticbreastcancer(WPBC),andBreastcancercoimbra(BCC),theobtainedresults clearly demonstratethesuperiorityoftheproposedmethodoverthestate-of-the-artmethods.
