Ka Netflix makana hoʻohana hamama kāhea e kilokilo a kiʻiʻoniʻoni poe kanaka, e like.
Ka mea pono ike hamama kapa pāhana ka Netflix uku. Netflix ka mea, he Online Movie hoolimalima poe, a ma ka makahiki 2000 iho a hemo Cinematch, he hana e waiho kiʻiʻoniʻoni i nā mea kūʻai mai. No ka mea, laʻana, Cinematch ke hai ia oukou makemake Star Wars a me aupuni a pepehi Back, a laila, paipai aku ia oukou i kiai hoi o ka Jedi. Initially, Cinematch hana poorly. Aka, ma luna o ka papa o na makahiki, Cinematch mau e hoʻoikaika i kona hiki pono ke kilokilo i kiʻiʻoniʻoni nā mea kūʻai mai eʻai. I ka 2006, naʻe, holomua ma Cinematch plateaued. I ka noiʻi ma Netflix i hoaoia nani nui na mea a pau ia lakou ke manao ai, aka, i ka manawa hookahi, lakou i manao ai he poe na manaʻo i ke kokua mai ia lakou hoʻoikaika 'ana i ko lākou nenoaiu. Pela, hele mai la lakou i ka mea ia, i ka manawa, he radical pāʻoihana, he hamama kāhea.
Pilikia i ka eventual pomaikai o ka Netflix lua,ʻo ia i ka leo kahea e hamama ana, ua hoʻololi i, a me keia manao i nui nā haʻawina no ka hamama kelepona mai e hiki ai ke hoʻohana 'ia no ka lawelawe noiʻi. Netflix i pono kau aku i unstructured noi no ka manaʻo,ʻo ia hoʻi ka mea a na kanaka hoi i noonoo i ka wa a lakou i noonoo i hamama kahea mua. E aho, Netflix posed i maopopo pilikia me ka mea loiloi 'ana hoʻohālike; lākouʻaʻa kanaka e ho ohana i ke kaʻina o 100 miliona Movie Estate e kilokilo 3 miliona e paa ana ia-aku Estate (Estate i nā mea hoʻohana i hana ai, aka, aole i hookuu aku i Netflix). Ka mea hiki ho okumu i ka algorithm i ke kilokilo i ka 3 miliona paa-aku Estate 10% maikaʻi ma mua o Cinematch e lanakila 1 miliona dala. Keia ike a me ka oluolu e pili loiloi 'ana hoʻohālike-ke kapakai pukana Estate i paʻa-i Estate-i manaoia e ka Netflix makana i ka honua iloko o ia ka ala i pāʻoihana, ua hiki pono e nānā mamua paha; ka mea huli i ka hakaka ana o ka hoʻomaikaʻi Cinematch iloko o ka pilikia kupono no ka hamama kahea.
InʻOkakopa i ka makahiki 2006, Netflix kuu kekahi dataset hoopii 100 miliona Movie Estate mai ana ma kahi o 500,000 nā mea kūʻai mai (kakou e noonoo i ka pilikino implications o keia aeaiiuo kala ma ka Mokuna 6). Ka Netflix aeaiiua hiki ke conceptualized e like me ka nui'ōpū mai i ke kaha 500.000 nā mea kūʻai mai i ka 20,000 kiʻiʻoniʻoni. Iloko o keia mua, ua kokoke 100 miliona Estate ma ka pālākiō mai 1 ai 5 na hoku (Oaaeeoea 5.2). Ka hana nui loa ia e hoʻohana i ka malama aeaiiua i loko o ka'ōpū mai, e wńnana i ka 3 miliona paa-i Estate.

Noiʻi, a me hackers a puni ke ao nei, ua hōʻailonaʻia i ka hana nui loa, a me ka 2008 oi aku mamua o 30,000 poʻe ma luna o ia mea, ua hana (Thompson 2008) . Ma luna o ka papa o ka hoʻokūkū, Netflix loaa oi aku mamua o 40.000 i manaoia pāʻoihana mai oi aku mamua o 5,000 eiiaiaeu (Netflix 2009) . ʻae Nō hoʻi, Netflix hiki ole heluhelu a hoʻomaopopo i kēia mau i manaoia pāʻoihana. Ka pau mea holo smoothly, nae, no ka mea, o ka pāʻoihana, ua oluolu i ka huli. Netflix hiki wale i ka kamepiula hoohalike i ka pukana Estate a hiki i ka paʻa, i Estate, ma ka mālama '-i hoakaka ia metric (o ka nui o kēia mau metric la lakou ia ia i ka huinahalike kumu o ka uuku-kihikihiʻo hewa o keia hoopunipuni). He mea keia e hiki koke loiloi i pāʻoihana i hoʻohana 'Netflix e lawe pāʻoihana mai a pau, i huli mai no ka maikai manaʻo i hele mai, mai kekahi mau kahaha ko oukou naau wahi e noho nui. I ka mea, ua waihoia ma ka hui ho'ālaʻia ekolu noiʻi mea, aohe ana ma mua o ka hoao ana hale maikam manaʻo paipai nenoai ka eo pāʻoihana (Bell, Koren, and Volinsky 2010) .
Hookahi nani, ao ke ano o ka Netflix makana no ia mea hoʻohana a pau i loko o ke ao nei, e loaa ia lakou ko pāʻoihana loiloi 'ma mull wale. I ka wa a na kanaka i ko lakou Uploaded pukana Estate, aole lakou i pono, e hoʻouka i ko nā credentials, i ko lakou mau makahiki, heihei, hoohanau, moe kohoʻia, ai ole ia i kekahi mea no lakou iho. Pela, ua hana like ka pukana Estate o ka Kumu kaulana mai Stanford ia e like me ka poe mai ka teenager iloko o kona keena moe. Eia naʻe, i keia mea i paa io ole i ka loa nohona noiʻi. Ia mea, no ka mea, mea nohona noiʻi, loiloi 'ana he manawa e hoopau ana a me ka hapa' ia 'pilikino. No laila, nui noiʻi i ka manaʻo nui ua loa seriously loiloi, a me ka wa manaʻo ua loiloi ', he mea paakiki e hoʻokaʻawale mau loiloi mai i ka mea nāna i hana aku o ka manaʻo. No ka mea, pāʻoihana, he oluolu, e huli, e wehe ae kāhea aku a ke 'ae i noiʻi e nānā i nā pāʻoihana potentially kupanaha mea e haule iho ma na mawae, ina lakou i manao wale pāʻoihana mai kaulana Kumu.
No ka mea, laʻana, ma kekahi welau ma ka Netflix makana ka mea, me ka pale inoa o Simona Funk like ma luna o kona Blog i manaoia pāʻoihana ma muli o ka singular cia decomposition, he hoʻokokoke mai ka laina hōʻailona helu i i ole i hoʻohana muaʻia e kekahi i komo. Funk ka moʻomanaʻo wahi o ka poʻe oaoieei-yeiiiie? Weirdly ka hoʻomaʻamaʻa. Ua keia moʻomanaʻo pou hōʻike no ka pāʻoihana maikai, ina paha he mea he neoneo o ka manawa? Mawaho o ka hamama kahea pāhana, i ka pāʻoihana e ole, ua loaa mea loiloi. Ma hope o Simona Funk, aole he Kumu ma CALORIESʻenehana a me mit; ka mea, he polokalamu nā mea haku polokalamu ka mea, i ka manawa, ua backpacking puni New Zealand (Piatetsky 2007) . Inā ka mea, ua uilaʻoe i kēia manaʻo i ka engineer ma Netflix, he aneane oiaio, ina aole i lawe seriously.
Mea pōmaikaʻi, no ka mea, o ka loiloi 'ana hoʻohālike, ua ike a me ka oluolu i ka pili, ua loiloi' kona pukana Estate, a ua koke ike i kona hoʻokokoke, ua ikaika loa; oia rocketed i ka ha o ka wahi ma ke Competition, he weliweli hopena i haawiia mai e hui'ē aʻe i mua i hana no ka mea, malama no o ka pilikia. Ma ka hopena, ua hoʻohana 'ia e virtually na mea nā kānaka hoʻokūkū hapa o Simona Funk ka wanaao oia (Bell, Koren, and Volinsky 2010) .
I ka mea a Simona Funk koho, e kakau i ka moʻomanaʻo pou wehewehe i kona hoʻokokoke mai, ma mua o ho'āʻo e mālama ia mea huna, no hoi kahaki ii ka ia he nui loa i komo i loko o ka Netflix makana i wale nō kūpaʻa ma ka miliona dala uku. E aho, he nui aku i komo hoi mea eʻai i ka 'imi naʻauao hana nui loa ia, a me ke kaiāulu i hoʻomohala a puni ka pilikia (Thompson 2008) , manaʻo ka mea aʻu i makemake nui noiʻi e hoʻomaopopo.
Ka Netflix makana, he Classic mamuli o ka hamama kahea. Netflix posed i ka ninau me kekahi pahuhopu (luaÿi Movie Estate) a noi aku pāʻoihana mai na kanaka he nui. Netflix, ua hiki i ka loiloi i keia mau pāʻoihana, no ka mea, ua hiki pono o ka hōʻoia ma mua o ka hana, a ultimately Netflix lalau i ka maikaʻi loa pāʻoihana. A malaila, au e hoike aku ia oukou i keia ua kokoke loa i kahi e hiki ai ke hoohana ia ma ka biology a me ka kanawai.
