4.5.1.3 Ua koj tus kheej cov khoom

Lub tsev koj tus kheej cov khoom no yog high-kev pheej hmoo, high-nqi zog. Tab sis, yog hais tias nws ua hauj lwm, koj yuav pab tau los ntawm ib tug zoo tswv yim voj uas enables yus kev tshawb fawb.

Noj qhov mus kom ze ntawm lub tsev koj tus kheej xyaum ua tej yam ib kauj ruam ntxiv, ib co kev soj ntsuam ua tau tsim lawv tus kheej cov khoom. Cov khoom uas nyiam tuaj koom, thiab ces pab raws li platforms rau thwmsim thiab lwm yam ntawm kev tshawb fawb. Piv txwv li, ib tug pab pawg neeg ntawm soj ntsuam nyob rau hauv lub University of Minnesota tsim MovieLens , uas muab kev pab dawb, uas tsis yog-coj mus muag tus kheej yeeb yam tswv yim pom zoo. MovieLens tau ua tsis tu ncua txij li thaum 1997, thiab thaum lub sij hawm lub sij hawm no 250,000 sau npe cov neeg siv tau muab ntau tshaj 20 lab kev hais txog ntau tshaj li 30,000 movies (Harper and Konstan 2015) . MovieLens tau siv lub active zej zog ntawm cov neeg siv rau kev zoo kev tshawb fawb xws li los ntawm kev soj ntsuam kev kawm theories txog kev pab rau pej xeem cov khoom (Beenen et al. 2004; Cosley et al. 2005; Chen et al. 2010; Ren et al. 2012) los hais algorithmic txoj kev sib tw nyob rau hauv kev pom zoo systems (Rashid et al. 2002; Drenner et al. 2006; Harper, Sen, and Frankowski 2007; Ekstrand et al. 2015) ; rau ib tug tag nrho cov saib xyuas saib Harper and Konstan (2015) . Muaj ntau ntawm cov thwmsim yuav tsis tau tau tsis tau soj ntsuam muaj tiav tswj ib tug tiag tiag ua hauj lwm cov khoom.

Tu siab, lub tsev rau koj tus kheej cov khoom no yog incredibly yooj yim, thiab koj yuav tsum xav seb nws zoo li tsim ib tug start-up tuam txhab: high-kev pheej hmoo, high-nqi zog. Yog hais tias nws yog kev vam meej, qhov no mus kom ze muaj ntau npaum li cas ntawm cov tswj los ntawm lub tsev koj tus kheej xyaum ua tej yam nrog lub realism thiab koom nrog los ntawm ua hauj lwm nyob rau hauv uas twb muaj lawm systems.

Tab sis, kuv kev cia siab yog tias qhov no zoo yuav ua ntau cov tswv yim raws li technology pab. Cov teeb meem nrog tsim koj tus kheej cov khoom txhais hais tias soj ntsuam uas xav kom tswj tau ib yam khoom yog cov ntau ntau yuav ua rau tus hlub nrog ib lub tuam txhab, lub npe Kuv mam li nyob tom ntej no.

Xam 4.15: Yog hais tias koj yuav ntse ua rau koj tus kheej cov khoom, koj yuav tau txais txiaj ntsim los ntawm ib tug zoo tswv yim voj: kev tshawb fawb ua rau ib tug zoo dua cov khoom uas ua rau yus ntau cov neeg uas ua rau yus ntau heev tshaj dua kev tshawb fawb.
