Ubwubatsi
Ibikoresho byubuhanga nubukorikori bwo guhindura amakuru yibanze muburyo bwo gutanga amakuru (ibiranga) bifasha icyitegererezo kwiga.
Incamake
In classic machine learning it is often the single biggest driver of accuracy, more than the choice of algorithm.
Kwibira cyane
Icyitegererezo gishobora gusa kwigira kubisubizo ubiha, kandi amakuru yibanze ni gake agera muburyo bwingirakamaro. Imiterere yubuhanga irabisubiramo: gukuramo umunsi-wicyumweru uhereye igihe cyagenwe, kubara ikigereranyo cyumukiriya waguze, kodegisi ibyiciro nkumubare, gupima agaciro kumurongo umwe, cyangwa guhuza inkingi mubipimo. Byakozwe neza, byerekana uburyo algorithm ikeneye, kuburyo bworoshye kuburyo bukomeye buranga akenshi butera icyitegererezo kijyanye namakuru yibanze. Irasaba kandi ubumenyi bwa domaine, kubera ko uzi ko, vuga, 'transaction kumunota' byerekana uburiganya nibyo bitera ikintu gikomeye. Ibyago bya kera ni ukumenyekanisha amakuru, kubwimpanuka kubaka ikintu kiva mumakuru ataboneka mugihe cyo guhanura, cyerekana amanota y'ibizamini ariko bikananirana mubikorwa. Kwiga byimbitse byikora bimwe muribi, ariko ibibazo byubatswe / imbonerahamwe biracyashingira cyane kuri byo.
Ubushishozi
Ubuhanga busanzwe burimo ibisanzwe cyangwa ibisanzwe (gupima umubare kuburyo nta kintu na kimwe cyiganje), kimwe-gishyushye cyangwa intego yo gushushanya ibyiciro bitandukanye, binning indangagaciro zikomeza, no gukora imikoranire cyangwa ibintu rusange. Indero ihambaye ikwiye guhinduka (nkibisobanuro bya scaler hamwe no gutandukana bisanzwe) gusa kumibare yamahugurwa, hanyuma ukayashyira mubikorwa no kwemeza ibizamini. Kubara kuri dataset yuzuye itanga amakuru kandi itanga ibisubizo birenze ibyiringiro bitazakomeza kubohereza.
Ingaruka z'Ingamba
Ibyemezo bisobanutse
Iragufasha gutandukanya ibyifuzo bya tekiniki bisobanutse nururimi rwo kwamamaza.
Igiciro na bije
Urashobora kubaza ibibazo byiza byo gushyira mubikorwa mbere yo gukoresha amafaranga cyangwa igihe.
Itsinda hamwe nakazi
Amakipe asangiye ibitekerezo akora ibicuruzwa byiza, politiki, nibyemezo byo kwiga.
Ejo hazaza h'ubwubatsi
Kwiga byimbitse byahinduye uburyo bwo gukuramo amashusho, amajwi, hamwe ninyandiko, aho imiyoboro yiga ibyerekanwe biturutse kumasoko mbisi. Ariko kubijyanye nimbonerahamwe nubucuruzi, namakuru menshi yibikorwa, ibitekerezo byubaka bitekereje bikomeza. Umwanya urimo uhindukirira kuri automatike (AutoML, ibyikora byikora byikora) hamwe nogukoresha 'ububiko bwibikoresho' byemerera amakipe gusangira ibintu bihoraho, byageragejwe neza murugero. Tegereza ibikoresho byinshi byerekana ibiranga n'abashinzwe kwirinda kumeneka, mugihe ubuhanga bwa domaine bwabantu buguma nkenerwa kubintu bifite agaciro kanini.
Gushyira mu bikorwa Isi
Kugaragaza uburiganya: gukuramo ibintu nkibikorwa byinshyi, igihe cyo kugura ubushize, nintera iva ahantu hasanzwe.
Guteganya ibyifuzo: gukuramo umunsi-wicyumweru, ibendera ryibiruhuko, hamwe nimpuzandengo yikigereranyo cyo kugurisha mbisi.
Gutanga inguzanyo: guhindura amateka mabi mubipimo nkumwenda-winjiza numubare wubwishyu bwatinze.
Abakiriya churn: guteranya ibikorwa mubintu nka login buri kwezi niminsi kuva basezeranye bwa nyuma.
Ingaruka & Kurinda
Amakipe atandukanye arashobora gukoresha ijambo rimwe muburyo butandukanye, sobanura intera hakiri kare.
Ibipimo birashobora kugaragara bikomeye mugihe imikorere-yisi-itaringaniye.
Kwirengagiza ubuziranenge bwamakuru na gahunda yo gusuzuma akenshi bitanga ibisubizo byoroshye.
Igishushanyo mbonera
Tangira nururimi rusobanutse rwibisubizo ukeneye.
Toranya intsinzi imwe hamwe nuburyo bumwe bwo gutsindwa mbere yo kwipimisha.
Koresha umuderevu muto hamwe namakuru ahagarariye, ntabwo ari demo yashizweho.
Inyandiko aho Feature Engineering ifasha nuburyo bworoshye bworoshye nibyiza.

What is Feature Engineering?
Imiterere yubuhanga nubukorikori bwo guhindura amakuru yibanze muburyo bwo gutanga amakuru (ibiranga) bifasha icyitegererezo kwiga. Mu mashini ya kera yiga imashini nimwe mumashanyarazi manini yukuri, kuruta guhitamo algorithm.
Ubwubatsi buranga iki?
Imiterere yubuhanga nijyanye no gukora inyongeramusaruro (ibiranga) uhereye kumibare fatizo kugirango icyitegererezo kibone ingero zingirakamaro.
Ni ukubera iki ubuhanga bwubwubatsi bukunze gusobanurwa nkibyingenzi mukwiga imashini za kera?
Ku makuru yubatswe, ibintu byateguwe neza akenshi bifite akamaro kuruta icyitegererezo cyihariye, bityo moderi yoroshye kubintu bikomeye irashobora gutsinda.
Ni ubuhe buryo bwo kumena amakuru mubikorwa byubwubatsi?
Kumeneka bisobanura ikintu cyinjira mumakuru utari kugira mubyukuri mugihe cyo guhanura, kuzamura amanota y'ibizamini ariko kunanirwa mubikorwa.
Mugihe ibipimo byo gupima (urugero, uburinganire), nihe ukwiye kubara uburyo bwo gutandukana no gutandukana?
Guhuza ibipimo byamahugurwa gusa, hanyuma ukabishyira ahandi, birinda kumeneka kandi bitanga igereranya ryimikorere.
Ninde muribi muburyo busanzwe bwa tekinoroji yubuhanga bwamakuru atandukanye?
Impinduka zicyiciro zisanzwe zihindurwa mumibare ukoresheje imwe-ishyushye cyangwa intego ya kodegisi kugirango moderi zishobore kuzikoresha.
