The LDA Feature Extraction Technique requires that all the samples are available in advance. Zvisinei, pane mamiriro ezvinhu apo yose date yakatarwa haisi kuwanikwa uye chiyamuro mashoko anocherechedzwa somunhu rukova. Muchiitiko ichi, zviri anodiwa kuti LDA Feature Extraction kuti kukwanisa kunatsurudza computed LDA zvinhu nokucherechedza itsva mimwe pasina kumhanya algorithm pamusoro yose date yakatarwa. Somuenzaniso, mune zvakawanda-chaizvoizvo-nguva zvikumbiro akadai Mobile robotics kana paIndaneti chiso kuzivikanwa, zvakakosha kuti kunatsurudza dzakatorwa LDA zvinhu nokukurumidza sezvo itsva observations dziripo.
LDA chinhu dzokubudisa kuti kukwanisa kunatsurudza akaverenga LDA zvinhu nokucherechedza ivhu itsva
