A / B Ikizamini cya ML Model
Igeragezwa rya A / B ryerekana moderi bisobanura guhuza traffic traffic kuri verisiyo ebyiri yicyitegererezo icyarimwe no gupima imwe ikora neza kubakoresha nyabyo nibisubizo nyabyo.
Incamake
It matters because offline accuracy metrics often fail to predict business impact, so the only honest test is a controlled experiment in production.
Kwibira cyane
Offline icyitegererezo gishobora kugaragara neza - AUC yo hejuru, ikosa ryo hasi - nyamara uracyababaza ibipimo witaho, nkinjiza cyangwa kugumana. Ikizamini cya A / B gikemura ibi muburyo bwo gutandukanya abakoresha mumatsinda yo kugenzura ikorwa nicyitegererezo gihari (A) hamwe nitsinda rivura ryatanzwe nabakandida (B), hanyuma ugereranya ibipimo byatoranijwe. Kwimenyekanisha byemeza ko amatsinda agereranywa, bityo itandukaniro iryo ariryo ryose rishobora kwitirirwa icyitegererezo. Amakipe akoresha ibizamini bya hypothesis kugirango amenye niba icyuho cyagaragaye ari urusaku cyangwa urusaku gusa, rushyiraho urwego rukomeye (akenshi 5%) no kubara ingano yicyitegererezo ikenewe kugirango imbaraga z’ibarurishamibare zihagije. Tekinike ijyanye nayo irimo gusohora canary, aho ijanisha rito ryimodoka igerageza moderi nshya mbere, hamwe nigeragezwa ryigicucu, aho icyitegererezo gishya gitanga ibyifuzo bitagize ingaruka kubakoresha.
Ubushishozi
Intangiriro ni ikizamini cya hypothesis. Impfabusa null ivuga ko moderi zombi zikora kimwe; urabyanze gusa niba itandukaniro rifite imibare ihambaye ukurikije itandukaniro nubunini bw'icyitegererezo. A p-agaciro munsi yurugero rwawe (vuga 0.05) yerekana ibisubizo bidashoboka mumahirwe meza. Isesengura ryimbaraga imbere rirakubwira umubare wabakoresha ukeneye kumenya neza ingaruka zifatika - iterambere rito riteganijwe risaba urugero runini rwo kwemeza.

Ejo hazaza ha A / B Ikizamini cya ML Model
Ubushakashatsi burimo kugana kugabanwa neza. Ibigwi byinshi byitwa bandit algorithms bihinduranya traffic nyinshi kuri moderi ikora neza mugihe ikizamini gikora, bikagabanya ikiguzi cyo gukora moderi mbi. Witegereze ibipimo byizamu byikora bihagarika igeragezwa niba icyitegererezo cyangiza umutekano cyangwa ubutabera, ikizamini gikurikiranye cyemerera amakipe kureba ibisubizo bitarinze guhishira ibyiza, hamwe na platform ikora ubushakashatsi bwinshi bwa ML icyarimwe.
Gushyira mu bikorwa Isi
Serivise itambuka A / B igerageza uburyo bushya bwo gusaba, gupima igihe cyo kureba kuri buri mukoresha kuruta kurutonde rwa interineti.
Urubuga rwa e-ubucuruzi canary-rusohora uburyo bushya bwo gushakisha-kugeza kuri 5% yimodoka mbere yuko itangira.
Igicucu cya banki igerageza uburyo bushya bwuburiganya mu buryo bubangikanye, ugereranije imenyesha ryayo na moderi nzima nta guhagarika ibikorwa.
Porogaramu yo gutwara ibinyabiziga ikoresha amabandi menshi yitwaje intwaro kugirango isabe inzira hagati yimiterere yibiciro, itonesha uwutwara byinshi byuzuye.
Ingaruka & Kurinda
Gutezimbere igipimo kimwe gishobora guhisha intege nke za sisitemu.
Ibikorwa Remezo no kubungabunga akenshi usanga bidahabwa agaciro.
Icyuho cyumutekano no kwitegereza birashobora kwiyongera uko sisitemu igenda igorana.
Igishushanyo mbonera
Sobanura ubukererwe, ubuziranenge, nigiciro cyibiciro mbere yo kubishyira mubikorwa.
Ibipimo byerekana umutwaro ufatika hamwe namakuru yimiterere.
Gukurikirana ibikoresho kubikosa, drift, ningaruka zabakoresha.

What is A/B Testing for ML Models?
Igeragezwa rya A / B ryerekana moderi bisobanura guhuza traffic traffic kuri verisiyo ebyiri yicyitegererezo icyarimwe no gupima imwe ikora neza kubakoresha nyabyo nibisubizo nyabyo. Nibyingenzi kuberako ibipimo byukuri bitagaragara kuri interineti akenshi binanirwa guhanura ingaruka zubucuruzi, kubwibyo ikizamini cyinyangamugayo gusa ni igeragezwa rigenzurwa mubikorwa.
Kuki amakipe A / B yerekana ikigereranyo mubikorwa aho kwizera ibipimo bya interineti?
Kurenza umurongo wa interineti ntabwo byemeza umusaruro mwiza wukuri kwisi nko kwinjiza cyangwa gusezerana, bityo igeragezwa rizima nikizamini nyacyo.
Ni uruhe ruhare umukoro uteganijwe ugira mu kizamini cya A / B.
Kwimenyekanisha bituma amatsinda abiri asa muburyo butandukanye kuburyo itandukaniro ryose mubisubizo rishobora kwitirirwa ihinduka ryikitegererezo.
Niki amabandi yitwaje intwaro menshi akora mugihe cyubushakashatsi?
Algorithms ya bandit ihindagurika igenera traffic nyinshi kurugero rwatsinze, kugabanya ikiguzi cyo gukorera nabi.
Niyihe ntego yo gusesengura imbaraga mbere yikizamini cya A / B.
Isesengura ryimbaraga rigena ingano yicyitegererezo isabwa kugirango tumenye neza ingaruka yubunini runaka, wirinde ibizamini bidashoboka.
