Ukuthola Amamethrikhi Okuhlola Okubalulekile
Emhlabeni oguquguqukayo Wokufunda Komshini, ukuhlola ngokunembile ukusebenza kwemodeli kubalulekile. Lokhu kuqeqeshwa kukwethulela kumamethrikhi okuhlola abalulekile. Isici esibalulekile sokwahlulela ukusebenza kahle kwemodeli ye-ML. Uzoqondiswa kuma-nuances amamethrikhi ahlukene, njengokunemba, ukuzwela, nokucacisa, okudlala indima ebalulekile ekunqumeni ikhwalithi yemodeli.
Njengoba uqhubeka, uzofunda ukuhumusha ngokujulile lawa mamethrikhi, okukuvumela ukuthi wenze ukuhlola okunolwazi nokunembile. Leli khono libaluleke kakhulu emkhakheni wezobuchwepheshe, lapho izinqumo ezisekelwe kudatha ethembekile zingaba nomthelela omkhulu empumelelweni yebhizinisi.
Ukwengeza, ukuqeqeshwa kugcizelela ukubaluleka kokuqinisekisa okuphambene, indlela esiza ukuqinisekisa ukuthi imodeli yakho iqinile futhi iyakwazi ukukhiqiza idatha entsha. Uzokwaziswa nezindlela zokuphatha amasethi edatha angalingani, inselele evamile ekufundeni komshini.
Ukujula Kwezindlela Zokuqinisekisa
Uzophinde ungene ujule kumasu okuqinisekisa amamodeli wokufunda komshini athuthukile. Ukugcizelelwa ngokukhethekile kubekwa ekuqinisekiseni okuphambene, indlela ehlola ikhono lemodeli lokwenza okuvamile, kusetshenziswa izingxenye ezihlukene zedatha zokuqeqesha nokuhlola. Le nqubo ibalulekile ukuze ugweme ukugcwala ngokweqile futhi uqinisekise ukuthi imodeli yakho iqinile futhi ithembekile.
Uzokwaziswa futhi emicabangweni efana nejika le-ROC nendawo engaphansi kwejika (AUC), amathuluzi abalulekile okuhlola ukusebenza kwamamodeli wokuhlukanisa. Le mibono izokusiza ukuthi uqonde ngokujule kakhudlwana ukuthi ungayihlola kanjani ikhwalithi nokuthembeka kwemodeli, inikeze ukuhlaziya okuguquguqukayo kokusebenza kwemodeli.
Ukwengeza, ukuqeqeshwa kukuqondisa ezinyathelweni ezingokoqobo zokuqalisa lezi zindlela zokuhlola, zikunikeza izibonelo zempilo yangempela kanye nezifundo eziyisibonelo ukuze ufanekise imiqondo yetiyori. Le ndlela yokusebenza ngezandla izokusiza ukuthi uthole ukuzethemba nekhono lokuhlola amamodeli e-ML.
Faka Emsebenzini: Ukuhlaziywa kanye Nokuhunyushwa Kwemiphumela
Kugcizelelwa ukusebenzisa ulwazi olutholiwe. Uzofunda ukuhlaziya nokuhumusha imiphumela yokuhlolwa kwemodeli yokufunda komshini, ikhono elibalulekile lanoma yimuphi uchwepheshe ofisa ukuvelela kulo mkhakha.
Uzoqondiswa ngenqubo yokuhlaziya imiphumela, ufunde ukukhomba amandla nobuthakathaka bemodeli. Lokhu kuhlaziya okubalulekile kuzokuvumela ukuthi wenze izincomo ezinolwazi zokwenza ngcono imodeli, kusize ukukhulisa ukusebenza kahle nokufeza izinhloso zamasu zenhlangano yakho.
Uzofunda ukuthi ungakwethula kanjani okutholile ngokucacile nangokukholisayo, wenze kube lula ukwenza izinqumo ezisekelwe ebufakazini ngaphakathi kwenhlangano yakho.
Ngokufunda kahle lawa makhono, uzokwazi ukubamba iqhaza elibalulekile emkhakheni Wokufunda Ngomshini, usize izinhlangano ukuthi zithuthukise amamodeli azo futhi zifeze izifiso zazo emhlabeni wezobuchwepheshe oshintsha njalo.
