Uhlolojikelele
Ukungalingani kwekilasi kulapho umphumela owodwa udlula kakhulu omunye - njengemisebenzi esemthethweni engu-99.9% iqhathaniswa nokukhwabanisa okungu-0.1% - okukhohlisa amamodeli ukuthi angaziba isigaba esingavamile kodwa esibalulekile. Ukwenza isampula kabusha kulinganisa kabusha idatha yokuqeqeshwa ukuze imodeli ifunde ukubona abambalwa.
Ukungalingani Kwekilasi kanye Nokusampula Kabusha kuyibhlokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Uma amakilasi ehlanekezelwe, imodeli ingakwazi ukushaya ukunemba okungu-99.9% ngokuhlale ibikezela iningi futhi ingalokothi ibambe umkhonyovu owodwa, okungenamsebenzi. Ukusampula kabusha kulungisa ukusatshalaliswa kokuqeqeshwa ngezindlela ezimbili ezibanzi. Ukuphinda kabili isampula noma kuhlanganiswe izibonelo ezimbalwa - i-SMOTE yakudala (I-Synthetic Minority Over-sampling Technique) idala amaphuzu amasha ngokuhlanganisa phakathi kwesampula yedlanzana nomakhelwane bayo abambalwa abaseduze kunokuba iwakopishe. Ukusampula okungaphansi kunalokho kulahla izibonelo eziningi (ngokungahleliwe, noma ngobuhlakani ngezindlela ezifana nezixhumanisi ze-Tomek noma i-NearMiss) ukuze kulungiswe izinto, ngezindleko zokulahla idatha. Ezinye izindlela ezigwema ukuthinta idatha zihlanganisa ukukala kwekilasi (ukujezisa amaphutha amancane kakhulu emsebenzini wokulahlekelwa) kanye nokulungisa umkhawulo wesinqumo ngemva kokuqeqeshwa.
I-Technical Insight
Umthetho obalulekile: sebenzisa kabusha isethi yokuqeqeshwa kuphela, ungalokothi uqinisekise noma isethi yokuhlola, futhi hlala wenze isampula kabusha ngaphakathi kwamafolda okuqinisekisa awela. Ukwenza isampula ngokweqile ngaphambi kokuhlukanisa kuvuza eduze kwamaphoyinti kusethi yokuhlola futhi kukhuphule amaphuzu. Ngenxa yokuthi ukunemba akusho lutho lapha, ukuhlola kufanele kuncike ekunembeni, ekukhumbuleni, ku-F1, ku-Precision-Recall AUC, noma ku-Matthews Correlation Coefficient — amamethrikhi ahlala ethembekile lapho ikilasi elihle liyivelakancane.
I-Mastering Class Ukungalingani kanye nokusampula kabusha
Ukungalingani kwekilasi kulapho umphumela owodwa udlula kakhulu omunye - njengemisebenzi esemthethweni engu-99.9% iqhathaniswa nokukhwabanisa okungu-0.1% - okukhohlisa amamodeli ukuthi angaziba isigaba esingavamile kodwa esibalulekile. Ukwenza isampula kabusha kulinganisa kabusha idatha yokuqeqeshwa ukuze imodeli ifunde ukubona abambalwa. Ukungalingani Kwekilasi kanye Nokusampula Kabusha kuyibhlokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha Ukungalingani Kwekilasi kanye Nokusampula Kabusha njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa Ukungalingani Kwekilasi kanye Nesampling athuthukisa izakhiwo, idatha, nokukhetha kwengqalasizinda ngokumelene nokuthembeka nezindleko. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka. Ngesikhathi esifanayo, Ukuthuthukisa ibhentshimakhi eyodwa kungafihla ubuthakathaka obubanzi besistimu. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
