Ii-algorithms ngoku zilawula i-ecosystem yedijithali, kuba "isikhokelo" sabo senza ukuba kube lula ukunika abasebenzisi iingcebiso ezizezakho, ngokusekwe kwiziphumo zophando, okanye kwidatha yabo. Kodwa hayi kuphela ezo algorithms ezisinceda sikhethe imuvi Netflix nokuba Amazon inalo msebenzi, njengoko benokuba negalelo kuphuculo lwe satellites.
Iziphumo zipapashwa kwi Ijenali yeHlabathi ye-Applied Earth Observation kunye ne-Geoinformation kwaye ubonise indlela ngezi algorithms, abaphandi bakwazile ukucacisa iindawo ezingenasigqubuthelo samafu kunye neendawo ezingaboniyo zokuhanjiswa kwesathelayithi.
Ngokulungelelanisa i-algorithm yengcebiso eyenzelwe iNetflix, uRuo-Qian (Roger) Wang, unjingalwazi oncedisayo kubunjineli boluntu kunye nokusingqongileyo kwiSikolo soBunjineli saseRutgers, udale inkqubo echaneke ngakumbi nekhawulezayo yokuqikelela imihlaba egutyungelwe ngamafu elunxwemeni. iindawo kunezixhobo eziqhelekileyo zokuzalisa idatha.
Le algorithm yeNetflix ibizwa ngokuba yiFunk-SVD, kwaye yenziwe nguSimon Funk ukwenza iyelenqe lophononongo lwabathengi kwimatrix.
"Amaqonga eenkonzo ze-elektroniki ezifana ne-Alibaba kunye ne-Amazon zisebenzisa iinkqubo zokuncoma, ezisebenzisa i-datasets ezinkulu ukubonelela ngeengcebiso zemveliso zomntu ukunceda abathengi benze izigqibo," watsho uWang. “Okwenza umdla kukuba, indlela inkqubo yedatha yabacebisi ayahlukanga kwinkqubo yokuqikelela umhlaba osithelwe ngamafu. »

I-algorithms yokuzaliswa kwamafu esetyenziswa kwi-remote sensing yokulinganisa idatha eqhubekayo, efana nobushushu bamanzi, umbala kunye nomxholo we-algal, ukwenza uqikelelo malunga nento efihliweyo.
Yinkqubo efanayo yokuzaliswa kwamafu: ulungelelwaniso ngalunye kwimephu lumelwe ngepixel ekwifoto, kwaye loo pixel inokuba ngamanzi okanye umhlaba, ngamafu amele idatha engabhalwanga. Ukulungiswa kukaWang kweFunk-SVD kwenza uqikelelo olufundisiweyo malunga nokuba yintoni ephantsi kwamafu ngokusekelwe kwezinye iindawo zedatha.
