Chiwerengero mu Data Mining

Kulemba ndi njira ya migodi yomwe imagwiritsa ntchito magulu kuti azitha kulongosola molondola ndi kuwunika. Amatchedwanso nthawi zina chotchedwa Decision Tree , kugawa njira ndi imodzi mwa njira zingapo zomwe zimayesetsedweratu kuti zisanthule madeta akuluakulu.

Nchifukwa Chiyani Kulemba?

Mazenera aakulu kwambiri akukhala otchuka m'dziko lamakono la "deta yaikulu." Tangoganizirani deta yamtundu wambiri yomwe imakhala ndi deta yamtundu wa deta.

Facebook yokha imagwiritsa ntchito ma tebriyiti 600 a ma data atsopano tsiku lililonse (kuyambira mu 2014, nthawi yotsiriza yomwe inafotokozera ma specs). Chovuta chachikulu cha deta yaikulu ndi momwe mungadziwire.

Ndipo kuchuluka kwa vuto si vuto lokha: deta yaikulu imakhalanso yosiyana, yosasinthika komanso yosintha mofulumira. Ganizirani deta yamakanema ndi mavidiyo, zolemba zamasewera, ma data 3D kapena geospatial data. Deta yamtundu uwu sichigawidwa mosavuta kapena kupangidwa mosavuta.

Pofuna kuthana ndi vutoli, njira zosiyanasiyana zopezera mfundo zothandiza zakhazikitsidwa, pakati pawo.

Momwe Mafotokozedwe Amagwirira Ntchito

Pangozi yoyendetsa kwambiri kuyankhula-tech, tiyeni tikambirane momwe magulu amagwirira ntchito. Cholinga chake ndi kukhazikitsa malamulo omwe angayankhe funso, kupanga chisankho, kapena kulongosola khalidwe. Poyambira, deta yolumikiza deta imapangidwa yomwe ili ndi makhalidwe ena komanso zotsatira zake.

Ntchito ya mndandanda wa masinthidwe ndi kuzindikira momwe zikhalidwezo zimagwirira ntchito.

Chitsanzo : Mwina kampani ya khadi la ngongole ikuyesera kudziwa zomwe mukufuna kulandira kupereka khadi la ngongole.

Izi zikhoza kukhala ndondomeko yake yophunzitsira deta:

Mitu ya "Predictor" Age , Gender , ndi Mapato a pachaka amadziwa kufunika kwa "kulingalira" chifukwa cha " Offer Credit Card ". Mu maphunziro oikidwa, chidziwitso chodziwika chimadziwika. Makhalidwe omwe amatsatira ndiye amayesa kuwona momwe ubwino wa chidziwitsocho unakhazikitsidwira: ndi ubale wanji umene ukupezeka pakati pa zowonongeka ndi chisankho? Zidzakhala ndi malamulo owonetsera, nthawi zambiri mawu / IFEN, mwachitsanzo:

Ngati (Age> 18 OR Age <75) NDI Ndalama Zapachaka> 40,000 PAMENE KUKHALA KUKHALA KUKHALA KUKHALA OKHALA = inde

Mwachiwonekere, ichi ndi chitsanzo chophweka, ndipo kusinthako kungafunikire zitsanzo zazikulu kwambiri za deta kusiyana ndi zolemba ziwiri zomwe zikuwonetsedwa apa. Kuwonjezera apo, maulosi amtunduwu akhoza kukhala ovuta kwambiri, kuphatikizapo malamulo ochepa kuti agwire zinthu zamatsenga.

Kenaka, chiwerengerochi chimaperekedwa "kudalitsika" kwa deta kuti awerenge, koma izi sizikhala ndi malingaliro (kapena chisankho):

Dongosolo lotsogolera likuthandizira kulingalira kuti kulondola kwa malongosoledwe a malamulowa, ndipo malamulowo amatha kufotokozera mpaka woyendetsa malingaliro akuwona kuti maulosiwa ali othandiza ndi othandiza.

Tsiku ndi Tsiku Zitsanzo za Kutchulidwa

Dongosolo, ndi njira zina zachinsinsi zamagetsi, ndikumbuyo kwa zochitika zathu zamasiku ndi tsiku monga ogula.

Maulosi am'derali angagwiritse ntchito magawo kuti afotokoze ngati tsiku lidzagwa, dzuwa kapena mitambo. Thandizo la zamankhwala lingaganizire za thanzi kuti liwonetsere zotsatira zachipatala. Njira yamagulu, a Naive Bayesian, amagwiritsira ntchito zofunikira kuti azigawa ma spam maimelo. Kuchokera pakudziwika kwachinyengo kwa zopangidwe zamagetsi, chiwerengero chiri pamasewero tsiku ndi tsiku kusanthula deta ndi kupereka maulosi.
