Uhlolojikelele
Isitolo sesici siyisistimu emaphakathi ehlanganisa, igcine, futhi inikeze okokufaka okuhlukile (izici) ezisetshenziswa amamodeli okufunda omshini. Ikhona ukuze kuqinisekiswe ukuthi amanani esici afanayo ncamashi asetshenziswa phakathi nokuqeqeshwa naphakathi nokubikezela okubukhoma, kuqedwa umthombo owaziwayo wokuhluleka kwemodeli ethule.
I-Feature Stores iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Amamodeli awafundi kudatha eluhlaza; bafunda ezicini ezifana 'nenani elijwayelekile lokuthenga ezinsukwini ezingu-30' noma 'isikhathi kusukela ekungeneni kokugcina.' Ngaphandle kwesitolo sesici, ithimba elilodwa libala labo abasemgqeni wokuqeqesha bese elinye liwafaka kabusha ngekhodi yokukhiqiza, futhi okubili kuyahlukana ngokuhlukana, inkinga ebizwa ngokuthi i-training-serving skew. Isitolo sesici sixazulula lokhu ngezendlalelo ezimbili ezivumelanisiwe: isitolo esingaxhunyiwe ku-inthanethi (inqolobane yedatha ephethe umlando weminyaka yokuqeqeshwa) kanye nesitolo se-inthanethi (isizindalwazi esisheshayo senani lokhiye esinikeza izici ngama-millisecond ngezicelo ezibukhoma). Zombili zigcwele izincazelo ezifanayo zesici. Amaqembu aphinde athole ikhathalogi eyabelwe ukuze izici ezakhelwe imodeli eyodwa zitholwe futhi ziphinde zisetshenziswe enye, kanye nokunemba kwephoyinti ngesikhathi okuvimbela ukuqeqeshwa ngephutha kudatha kusukela esikhathini esizayo.
I-Technical Insight
Inkinga enzima kakhulu exazululwa yisici sesitolo ukuhlanganisa ngesikhathi. Lapho wakha isethi yokuqeqeshwa, kufanele unamathisele amanani ezici njengoba ayenjalo ngesikhathi somcimbi ngamunye ongokomlando, hhayi amanani awo amanje, noma imodeli ifunda ekuvuzeni kwedatha. Isici sigcina isitembu sesikhathi kuwo wonke amanani futhi senze ukujoyina njenge-off ngokumelene nesitolo esingaxhunyiwe ku-inthanethi. Isitolo esiku-inthanethi, ngokuvamile i-Redis noma i-DynamoDB, siphethe kuphela inani lakamuva ngokhiye webhizinisi ngamunye wokubheka okungaphansi kwe-millisecond eyi-10 ngesikhathi sokunquma.
Izitolo Zesici Ezenza Uchwepheshe
Isitolo sesici siyisistimu emaphakathi ehlanganisa, igcine, futhi inikeze okokufaka okuhlukile (izici) ezisetshenziswa amamodeli okufunda omshini. Ikhona ukuze kuqinisekiswe ukuthi amanani esici afanayo ncamashi asetshenziswa phakathi nokuqeqeshwa naphakathi nokubikezela okubukhoma, kuqedwa umthombo owaziwayo wokuhluleka kwemodeli ethule. I-Feature Stores iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha I-Feature Stores 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-Feature Stores athuthukisa ukwakheka, idatha, nokukhetha kwengqalasizinda 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.
I-Strategic Impact
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka.
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka. Ekusetshenzisweni kwekhwalithi ephezulu, lokhu kuhunyushwa emithethweni yokusebenza elinganisekayo, imingcele yobunikazi, nemikhuba yokubuyekeza ephindelelayo ukuze amaqembu akwazi ukukala ukuzethemba esikhundleni sokukala ukungaqondakali.
Imfundo yobuchwepheshe isiza amaqembu ukuthi akhethe isitaki esifanele, hhayi nje esisha.

Ukuqaliswa Komhlaba Wangempela
Inkampani ekhokhayo igcina izici ze-transaction-velocity zamahora angu-24 esitolo se-inthanethi ukuze imodeli yayo yokukhwabanisa ikwazi ukuthola ukuswayipha ngaphansi kwama-millisecond angu-10.
Isevisi yokusakaza-bukhoma ichaza 'isikhathi sokubuka izinsuku eziyi-7 zokugcina' kanye esitolo sesici, bese siphinda sisisebenzisa kuwo wonke amamodeli anconyiwe, ama-churn, namamodeli okuhloswe ngawo izikhangiso.
Inkundla yokuboleka isebenzisa ukujoyina kwephoyinti-in-time ukuze kwakhiwe idatha yokuqeqeshwa, iqinisekisa ukuthi isinqumo ngasinye semalimboleko sibona kuphela izici zomfakisicelo ezaziwa ngaphambi kwaleso sinqumo.
Uhlelo lokusebenza lwe-ride-hailing lunikeza izici zesikhathi sangempela zokuhlinza nezici zokutholakala komshayeli kusukela kumugqa wesici sokusakaza-bukhoma kuya kumodeli yokuqagela ye-ETA.
