Ukufunyaniswa kweeModeli eziLawulwayo eziNgenamda
Kwihlabathi eliguquguqukayo lohlalutyo lwedatha, iimodeli ezigadiweyo ezingezona mgca zigqama njengezixhobo ezinamandla neziguquguqukayo. Ezi modeli, ezihamba ngaphaya kobuchule bomda besiqhelo, zenza kube lula ukujongana nemiba entsonkothileyo ngokuchaneka okukhulu. Olu qeqesho, lufikeleleka kwii-OpenClassrooms, lukunika ithuba elikhethekileyo lokuphonononga obu buchule buphucukileyo.
Ngelixa loqeqesho, uya kwaziswa ngeendlela ezahlukeneyo ezingeyomda, njengemithi yesigqibo kunye namahlathi angaqhelekanga. Ezi ndlela zobuchule, ezisetyenziswa ngokubanzi kwinkalo yenzululwazi yedatha, ziqatshelwa ngokukwazi kwazo ukulinganisa ubudlelwane obuntsonkothileyo phakathi kwezinto eziguquguqukayo.
Ugxininiso lubekwe ekuqondeni okubonakalayo kweengqikelelo, ngaloo ndlela kukuvumela ukuba uzisebenzise ngokufanelekileyo kwiiprojekthi zakho zexesha elizayo. Ngezandla-kwindlela yokufundisa, olu qeqesho lulungiselela ukuba ube yingcaphephe ekusebenziseni iimodeli eziphantsi kweliso elingenamgca.
Ngokuzibandakanya kolu qeqesho, uthatha umtsi omkhulu ekufumaneni izakhono ezixatyiswe kakhulu kushishino lwanamhlanje lwetekhnoloji. Ungaphoswa leli thuba lokuzahlula kwicandelo lohlalutyo lwedatha.
Nxilisa ulwazi lwakho lweModeli
Kwicandelo elisoloko liphuhla, kuyafuneka ukuba ukwazi ubuchule bamva nje. Esi sifundo siyakukhokela kwii-nuances zeemodeli eziphantsi kweliso elibukhali, ezikuvumela ukuba ufumane ukuqonda okunzulu nokwenyani kwezi zixhobo zibalulekileyo.
Uya kukhokelwa ukuba uphonononge iikhonsepthi eziphambili ezinje ngoomatshini be-vector yenkxaso (SVM) kunye nothungelwano lwe-neural, okuyizona zinto ziphambili kwinkalo yokufunda koomatshini. Ezi ndlela, ezaziwa ngokuchaneka kwazo kunye nokuguquguquka kwazo, ziyimpahla enkulu kwibhokisi yezixhobo zayo nayiphi na ingcali yedatha.
Uqeqesho lukwagxininisa ukubaluleka kokuqinisekiswa kwe-cross-validation kunye ne-hyperparameter optimization, amanyathelo abalulekileyo okuqinisekisa ukusebenza kunye nokuthembeka kweemodeli zakho. Uya kufunda ukuzazi kakuhle ezi nkqubo zintsonkothileyo ngokulula nangokuzithemba.
Ukongeza, uya kuba nethuba lokuziqhelanisa nezakhono zakho ezitsha ngeeprojekthi zehlabathi lokwenyani, okukuvumela ukuba udibanise ulwazi lwakho kwaye uzilungiselele imingeni yehlabathi yokwenyani. Le ndlela yokusebenza iqinisekisa ukuba awuyi kukwazi ukuqonda ezi ngcamango kuphela, kodwa kwaye uzisebenzise ngokufanelekileyo kwiiprojekthi zakho zexesha elizayo.
Fumanisa ubuChwephesha beModeli obukwinqanaba eliphezulu
Ezi ndlela, nangona zihambele phambili, zibonakaliswa ngendlela yokuba zifikeleleke nakwabo basebatsha entsimini.
Ugxininiso lukwabekwe ukubaluleka kovavanyo lwemodeli kunye nohlengahlengiso, amanyathelo abalulekileyo ekuqinisekiseni ukuba uhlalutyo lwakho luchanekile kwaye luthembekile. Uya kufunda ukukhangela ezi nkqubo ngokuqonda okucacileyo kwemigaqo esisiseko, ukukulungiselela ukuba ugqwese kwiinzame zakho zexesha elizayo.
Njengoko sele kukhankanyiwe, uqeqesho lukunika ithuba lokubandakanyeka kwiiprojekthi ezisebenzayo, ezikuvumela ukuba usebenzise izakhono ozifumene kwimeko yokwenyani. Le ndlela yokusebenza ayikulungiseleli nje ukuba uqonde iikhonsepthi zethiyori, kodwa kunye nokuzisebenzisa ngokufanelekileyo kwihlabathi lobuchwephesha.
Thatha eli thuba uzixhobise ngezakhono zokugqwesa kwicandelo elihlala livela lohlalutyo lwedatha.
