Ukutholwa Kwamamodeli Angawona Alayini Agadiwe
Emhlabeni oguquguqukayo wokuhlaziywa kwedatha, amamodeli angaqondile agadiwe agqama njengamathuluzi anamandla futhi aguquguqukayo. Lawa mamodeli, adlula amasu omugqa wendabuko, enza kube nokwenzeka ukubhekana nezinkinga eziyinkimbinkimbi ngokunemba okukhulu. Lokhu kuqeqeshwa, okufinyeleleka ku-OpenClassrooms, kukunikeza ithuba eliyingqayizivele lokuhlola lawa maqhinga athuthukile.
Phakathi nalokhu kuqeqeshwa, uzokwaziswa ngezindlela ezihlukahlukene ezingaqondile, njengezihlahla zesinqumo namahlathi angahleliwe. Lawa masu, asetshenziswa kakhulu emkhakheni wesayensi yedatha, abonwa ngekhono lawo lokubonisa ubudlelwano obuyinkimbinkimbi phakathi kokuguquguqukayo.
Kugcizelelwa ukuqonda okungokoqobo kwemiqondo, ngaleyo ndlela kukuvumela ukuthi uyisebenzise ngempumelelo kumaphrojekthi akho esikhathi esizayo. Ngendlela yokufundisa ngezandla, lokhu kuqeqeshwa kukulungiselela ukuthi ube uchwepheshe ekusetshenzisweni kwamamodeli angenawo umugqa agadiwe.
Ngokuzibandakanya kulokhu kuqeqeshwa, uthatha igxathu elikhulu ekutholeni amakhono aziswa kakhulu embonini yezobuchwepheshe yanamuhla. Ungaphuthelwa yileli thuba lokuzihlukanisa emkhakheni wokuhlaziya idatha.
Gxilisa Ulwazi Lwakho Lokumodela
Emkhakheni ovela njalo, kubalulekile ukwazi amasu akamuva. Lesi sifundo sikuqondisa kuma-nuances amamodeli angaqondile agadiwe, okukuvumela ukuthi uthole ukuqonda okujulile nokusebenzayo kwalawa mathuluzi abalulekile.
Uzoholelwa ekuhloleni imiqondo ethuthukile njengemishini ye-vector yokusekela (SVM) namanethiwekhi e-neural, okuyizinsika eziyinhloko emkhakheni wokufunda komshini. Lawa masu, aziwa ngokunemba nokuvumelana nezimo, ayimpahla enkulu ebhokisini lamathuluzi lanoma yimuphi uchwepheshe wedatha.
Ukuqeqeshwa kuphinde kugcizelele ukubaluleka kokuqinisekisa okuphambanayo kanye nokwenza kahle kwe-hyperparameter, izinyathelo ezibalulekile zokuqinisekisa ukusebenza nokuthembeka kwamamodeli akho. Uzofunda ukuzenza kahle lezi zinqubo eziyinkimbinkimbi kalula nangokuzethemba.
Ngaphezu kwalokho, uzoba nethuba lokuzijwayeza amakhono akho amasha ngamaphrojekthi omhlaba wangempela, okukuvumela ukuthi uhlanganise ulwazi lwakho futhi uzilungiselele izinselele zomhlaba wangempela. Le ndlela yokusebenza ngezandla iqinisekisa ukuthi ngeke nje ukwazi ukuqonda le mibono, kodwa futhi uyisebenzise ngokuphumelelayo kumaphrojekthi akho esikhathi esizayo.
Zitholele Amasu Okumodela Athuthukile
Lezi zindlela, nakuba sezithuthukisiwe, zethulwa ngendlela yokuthi zifinyeleleke ngisho nakulabo abasanda kufika ensimini.
Kuphinde kugcizelelwe ukubaluleka kokuhlola nokulungiswa kwemodeli, izinyathelo ezibalulekile zokuqinisekisa ukuthi ukuhlaziya kwakho kokubili kunembile futhi kuthembekile. Uzofunda ukuzulazula kulezi zinqubo ngokuqonda okucacile kwezimiso eziyisisekelo, okukulungiselela ukuba uphumelele emizamweni yakho yesikhathi esizayo.
Njengoba sekushiwo, ukuqeqeshwa kukunikeza ithuba lokuzibandakanya kumaphrojekthi asebenzayo, okukuvumela ukuthi usebenzise amakhono owatholile esimweni sangempela. Le ndlela yokusebenza ngezandla ayikulungiseleli nje kuphela ukuthi uqonde imiqondo yetiyori, kodwa futhi ukuyisebenzise ngokuphumelelayo emhlabeni wochwepheshe.
Thatha leli thuba ukuze uzihlomise ngamakhono ukuze uphumelele emkhakheni ovela njalo wokuhlaziya idatha.
