Xaqiijinta-Isdhaafsiga
Xaqiijinta isdhaafsigu waa farsamada dib-u-qaabaynta ee lagu qiyaasi karo sida ugu wanaagsan ee moodalku u guud ahaan doono xogta aan la arkin.
Dulmar
It makes better use of limited data and gives a more reliable performance estimate than a single train/test split.
quusid qoto dheer
Hal tareen/kala qaybsanaan ayaa ah mid jilicsan: buundada aad helaysaa waxay si aad ah ugu xidhan tahay safafka ku dhacay goobta imtixaanka. Xaqiijinta isdhaafsiga ayaa tan hagaajisa iyada oo beddesha doorka tijaabada. Xaqiijinta iskutallaabta k-laab, waxaad u qaybinaysaa xogta k-laabyo siman, ku tababar k-1 ka mid ah, qiimee laalaabyada la qabtay, oo ku celceli k jeer si saf kasta loo tijaabiyo hal mar. Celcelis ahaan buundooyinka k waxay soo saartaa qiyaas xasilloon iyo cabbir kala duwanaansho. Doorashooyinka guud waa 5 ama 10 laab. Kala duwanaanshiyaha waxaa ka mid ah k-laab la kala saaray (ilaalinta saamiga fasalka ee xogta aan dheeli tirnayn), ka bixitaan-hal-bax (k waxay la mid tahay tirada shaybaarrada), iyo qaybo taxane ah oo aan waligood u tababarin mustaqbalka si loo saadaaliyo wixii la soo dhaafay.
Aragtida Farsamada
Xaqiijinta iskutallaabtu waxay aad ugu awood badan tahay xulashada moodeelka iyo hagaajinta hyperparameter: waxaad barbardhigaysaa qaabaynta celceliska buunadooda ansaxinta halkii aad ka badnaan lahayd hal qayb. Burburka muhiimka ah waa daadinta xogta - diyaarin kasta oo 'arag' dhammaan xogta xogta (qoritaan, xulashada sifada, xisaabinta) waa inay ku habboonaato laallaab kasta, ma aha ka hor inta aan la kala qaadin, haddii kale qiyaastaadu waxay noqon doontaa mid rajo leh. Xaqiijinta isdhaafsiga ee Nsted ayaa ka soocaysa hagaajinta iyo qiimeynta ugu dambeysa si looga fogaado daadintan.
Saamaynta Istiraatijiyadeed
Go'aamo cad
Waxay kaa caawinaysaa inaad kala saartid sheegashooyinka farsamada cad iyo luqadda suuq-geynta.
Qiimaha iyo miisaaniyada
Waxaad waydiin kartaa su'aalo fulineed oo wanaagsan ka hor inta aadan lacag ama waqti bixin.
Kooxda iyo socodka shaqada
Kooxaha fahamka la wadaago waxay sameeyaan wax soo saar, siyaasad, iyo go'aano waxbarasho oo wanaagsan.
Mustaqbalka Xaqiijinta Isdhaafsiga
Sida xog-ururinta iyo moodooyinka u koraan, orodka k wareegyada tababarka buuxa ayaa noqda mid qaali ah, sidaa darteed xirfad-yaqaanadu waxay si isa soo taraysa u door bidaan hal-ku-dhig ansaxinta ballaaran oo la sameeyay oo loogu talagalay barasho qoto dheer iyada oo la ilaalinayo xaqiijinta iskutallaab ee xog-ururinta yaryar ama jaantuska. ML otomaatiga ah iyo aaladaha sida scikit-learn's GridSearchCV iyo Optuna waxay ku dubtaa xaqiijinta iskutallaabta ee raadinta hyperparameter asal ahaan. Cilmi-baadhistu waxay ku socotaa qiyaasaha ka jaban, dhuumaha u adkaysta daadinta, iyo ansixinta saxda ah ee kooxaysan, kala sareyn, iyo xogta wakhtiga ku xidhan.
Dhaqangelinta Adduunka-dhabta ah
Isticmaalka 5-laab-laba laab-la-laabashada si loo isbarbar dhigo dib-u-celinta saadka, kaynta random-ka, iyo kobcinta gradient ka hor inta aanad samayn hal nooc.
Ku dalbashada k- laab la kala saaray xogta xog-helidda khiyaanada oo aan dheeli tirnayn si laalaab kasta uu u hayo qiyaastii isla saamiga heerka naadir ah.
Raadinta GridSearchCV ama RandomizedSearchCV, taas oo ka gudubta xaqiijinta isku dhafka hyperparameterka si loo doorto goobaha ugu fiican.
Isticmaalka taxane-waqti-taxane ah (rogid/silsilad hore-u-gudbineed) isdhaafsi- ansaxinta si loo qiimeeyo saadaasha ama dalabka saadaalinta iyada oo aan la tababarin xogta mustaqbalka.
Khatarta & Dariiqyada Ilaalada
Kooxo kala duwan ayaa laga yaabaa inay isla erey u isticmaalaan si kala duwan, marka hore u qeex baaxadda.
Tilmaamaha ayaa u ekaan kara kuwo xooggan halka waxqabadka dhabta ah ee dunidu aanu sinnayn.
In la iska indho tiro tayada xogta iyo qorshayaasha qiimayntu waxay inta badan abuurtaa natiijooyin jilicsan.
Qorshe Hawleedka Dhaqangelinta
Ka bilow qeexidda luqadda cad ee natiijada aad u baahan tahay.
Dooro hal cabbir guusha iyo hal xaalad guuldarro ka hor tijaabada.
Ku orod duuliye yar oo wata xogta matale, ee ma aha bandhig muuqaal ah.

What is Cross-Validation?
Xaqiijinta isdhaafsigu waa farsamada dib-u-qaabaynta ee lagu qiyaasi karo sida ugu wanaagsan ee moodalku u guud ahaan doono xogta aan la arkin. Waxay si fiican u isticmaashaa xogta xaddidan waxayna bixisaa qiyaas waxqabad oo la isku halayn karo marka loo eego hal tareen/kala qaybsanaan tijaabo ah.
Heerarka k- laab-laabashada ansaxinta, imisa jeer ayaa dhibco kasta oo xog ah loo isticmaalaa tijaabada?
Laalaab kastaa wuxuu u adeegaa sidii tijaabada hal mar loo dhigay dhamaan wareegyada k, sidaas darteed muunad kasta hal mar ayaa la tijaabiyaa waxaana lagu tababaraa inta soo hartay.
Waa maxay faa'iidada ugu weyn ee k-laab isdhaafsiga ansaxinta hal tareen/kala qaybsanaan tijaabo ah?
Marka la isku celceliyo laalaabyo badan, ansaxinta isdhaafsigu waxay yaraynaysaa kala duwanaanshaha qiyaasta waxqabadka marka la barbar dhigo ku tiirsanaanta hal qaybsanaan ah.
Waa maxay sababta k-laabka caadiga ah ee ansaxinta iskutallaabtu aanay ku habboonayn saadaalinta taxanaha wakhtiga?
Isku shaandhaynta xogta waqti-dalbanta ahi waxay mustaqbalka u daadisaa tababarka, sidaa awgeed CV-ga-waqtiga-xilliyeedka wuxuu adeegsadaa kala qaybsanaan-soo-saareyntii hore oo kaliya oo ku tababarta indha-indhayntii hore.
