Uhlolojikelele
Ukufunda imisebenzi eminingi kuqeqesha imodeli eyodwa ukuthi yenze imisebenzi eminingana ehlobene ngesikhathi esisodwa, yabelane ngezethulo zangaphakathi kuyo yonkana. Ngokufunda isakhiwo esabiwe, umsebenzi ngamunye usiza omunye, ngokuvamile uthuthukisa ukunemba nokusebenza kahle kwedatha phezu kokuqeqeshwa kwamamodeli ahlukene.
I-Multi-Task Learning iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Esikhundleni sokwakha imodeli ehlukile ngomsebenzi ngamunye, ukufunda ngemisebenzi eminingi (i-MTL) isebenzisa umgogodla okwabelwana ngawo ohlanganisa amakhanda aqondene nomsebenzi othize. Inethiwekhi yokubona ozishayelayo, isibonelo, ingase yabelane ngesishumeki sombono bese ihlukana ibe amakhanda okuthola izimoto, ukuhlukanisa umgwaqo, nokulinganisa ukujula. Izendlalelo ezabiwe zifunda izici ezijwayelekile eziwusizo kuyo yonke imisebenzi, kuyilapho ikhanda ngalinye lisebenza ngokukhethekile. Lokhu kusebenza njengohlobo lokuchema okungenakuguqulwa kanye nokujwayela: amasiginali asuka kumsebenzi owodwa acindezela ukumelwa okwabelwana ngawo, anciphisa ukugcwala ngokweqile kanye nokwenza ngcono ukwenziwa okuvamile, ikakhulukazi uma eminye imisebenzi inedatha encane. Inselele enkulu ukulinganisa imisebenzi - uma isikali sayo sokulahlekelwa noma i-gradient ingqubuzana, umsebenzi owodwa ungabusa futhi eminye ihlupheke, inkinga ebizwa ngokuthi ukudluliswa okungalungile. Amasu afana nesisindo sokulahlekelwa, isisindo esisekelwe ekungaqinisekini, nokuhlinzwa kwegradient kuhloswe ukugcina imisebenzi isebenzisana kunokuba iqhudelane.
I-Technical Insight
Ingqikithi yempokophelo ivamise ukuba isamba esikaliwe sokulahlekelwa komsebenzi ngamunye, L = Σ wᵢ Lᵢ, futhi ukukhetha izisindo wᵢ kubalulekile ngoba imisebenzi iyahluka ngesilinganiso nobunzima. Ukwabelana ngepharamitha eqinile (isiqu esivamile, amakhanda ahlukene) kuyindlela elula nejwayelekile kakhulu; ukwabelana okuthambile kugcina amamodeli ahlukene ehlanganiswe ngokukhululekile. Ama-gradient ashayisanayo kuyo yonke imisebenzi angakhanselwa, ngakho-ke izindlela ezifana nesisindo sokungaqiniseki (ukufunda ngokuzenzakalelayo) noma i-PCGrad (ukukhipha izingxenye zegrediyenti ezingqubuzanayo) zisiza imisebenzi ukuziqeqesha ndawonye ngokuzinzile.
Ukuthola Ukufunda Kwemisebenzi Eminingi
Ukufunda imisebenzi eminingi kuqeqesha imodeli eyodwa ukuthi yenze imisebenzi eminingana ehlobene ngesikhathi esisodwa, yabelane ngezethulo zangaphakathi kuyo yonkana. Ngokufunda isakhiwo esabiwe, umsebenzi ngamunye usiza omunye, ngokuvamile uthuthukisa ukunemba nokusebenza kahle kwedatha phezu kokuqeqeshwa kwamamodeli ahlukene. I-Multi-Task Learning iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-Multi-Task Learning njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Multi-Task Learning athuthukisa ukukhetha kwezakhiwo, idatha, kanye nengqalasizinda 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.
