This paper focuseson the problemof a robust estimation of different transformationmatricesbasedon thewell knownlinear discriminantanalysis(LDA) as it is usedin automaticspeech recognition systems.We investigatethe effectof classdistributionswith artificial featuresandcompare theresultingFishercriterion. Thispapershowsthat it is notveryhelpfulto useonly theFishercriterion for anassessment of classseparability. Furthermore weaddressthe problemof dealingwith too manyadditionaldimensionsin… CONTINUE READING
