Kuyini i-AI Preprocessing?

Kuyini i-AI Preprocessing?

Impendulo emfushane: Ukucubungula kwangaphambili kwe-AI kuyisethi yezinyathelo eziphindaphindwayo eziguqula idatha eluhlaza, enokuguquguquka okuphezulu ibe okokufaka kwemodeli okuhambisanayo, okuhlanganisa ukuhlanza, ukufaka ikhodi, ukukala, ukwenza amathokheni, kanye nokuguqulwa kwesithombe. Kubalulekile ngoba uma okokufaka kokuqeqesha kanye nokokufaka kokukhiqiza kuhluka, amamodeli angahluleka buthule. Uma isinyathelo "sifunda" amapharamitha, sifake kudatha yokuqeqesha kuphela ukuze ugweme ukuvuza.

Ukucubungula kwangaphambili kwe-AI yikho konke okwenzayo kudatha eluhlaza ngaphambi (futhi ngezinye izikhathi ngesikhathi) sokuqeqeshwa noma ukuphetha ukuze imodeli ifunde kukho. Akukhona nje "ukuhlanza". Kuwukuhlanza, ukubumba, ukukala, ukufaka ikhodi, ukwandisa, kanye nokupakisha idatha ibe yisithombe esivumelanayo esingeke siphazamise imodeli yakho kamuva. [1]

Izinto ezibalulekile okufanele uzicabangele:

Incazelo : Ukucubungula kusengaphambili kuguqula amathebula angahluziwe, umbhalo, izithombe, kanye namalogi abe izici ezilungele imodeli.

Ukuvumelana : Sebenzisa izinguquko ezifanayo ngesikhathi sokuqeqeshwa kanye nokucabanga ukuze uvimbele ukwehluleka kokungafani.

Ukuvuza : Faka izikali, ama-encoder, nama-tokeniser kudatha yokuqeqesha kuphela.

Ukuphindaphindwa : Yakha amapayipi anezibalo ezingahlolwa, hhayi ukulandelana kwamaseli e-notebook okungahleliwe.

Ukuqapha ukukhiqizwa : Ukulandelela ukujika nokuzulazula ukuze okokufaka kunganciphisi ukusebenza kancane kancane.

Izihloko ongase uthande ukuzifunda ngemva kwalesi:

🔗 Indlela yokuhlola amamodeli e-AI ukuze athole ukusebenza kwangempela
Izindlela ezisebenzayo zokuhlola ukunemba, ukuqina, kanye nokubandlulula ngokushesha.

🔗 Ingabe i-AI yombhalo ibe yinkulumo futhi isebenza kanjani
Ichaza izisekelo ze-TTS, ukusetshenziswa okuyinhloko, kanye nemikhawulo evamile namuhla.

🔗 Ingabe i-AI ingafunda umbhalo wesandla ohambisanayo ngokunembile namuhla?
Ihlanganisa izinselele zokuqashelwa, amathuluzi angcono kakhulu, kanye namathiphu okunemba.

🔗 Inembile kangakanani i-AI emisebenzini evamile
Ihlukanisa izici zokunemba, izilinganiso, kanye nokuthembeka kwangempela.

Ukucubungula i-AI kusengaphambili ngolimi olulula (nokuthi yini engeyona) 🤝

Ukucubungula kwangaphambili kwe-AI ukuguqulwa kokufakwayo okungahluziwe (amathebula, umbhalo, izithombe, amalogi) kube izici ezilungele imodeli. Uma idatha engahluziwe iyigaraji elingcolile, ukucubungula kusengaphambili kuwukumaka amabhokisi, uphonsa udoti ophukile, nokubeka izinto ndawonye ukuze ukwazi ukuhamba ngaphandle kokulimala.

Akuyona imodeli ngokwayo. Yizinto ezenza imodeli ibe nokwenzeka:

  • ukuguqula izigaba zibe izinombolo (ezishisayo kakhulu, ezijwayelekile, njll.) [1]

  • ukukala ububanzi obukhulu bezinombolo bube ububanzi obuqondile (ukuma, ubuncane obuphezulu, njll.) [1]

  • ukufaka umbhalo kuma-ID okufaka (futhi ngokuvamile imaski yokunaka) [3]

  • ukushintsha usayizi/ukunqampuna izithombe nokusebenzisa ukuguqulwa okunqunyiwe vs okungahleliwe ngokufanele [4]

  • ukwakha amapayipi aphindaphindwayo ukuze ukuqeqeshwa kanye nokufakwayo "kwempilo yangempela" kungahlukani ngezindlela ezicashile [2]

Inothi elilodwa eliwusizo: “ukucubungula kusengaphambili” kuhlanganisa noma yini eyenzeka njalo ngaphambi kokuba imodeli ibone okufakwayo . Amanye amaqembu ahlukanisa lokhu ngokuthi “ubunjiniyela bezici” vs “ukuhlanza idatha”, kodwa empilweni yangempela leyo migqa ayicaci.

 

Ukucubungula kwangaphambili kwe-AI

Kungani ukucubungula i-AI kusengaphambili kubaluleke kakhulu kunalokho abantu abakuqaphelayo 😬

Imodeli ifana nephethini, hhayi umfundi wengqondo. Uma imibono yakho ingahambisani, imodeli ifunda imithetho engahambisani. Lokho akuyona ifilosofi, kungokoqobo ngendlela ebuhlungu.

Ukucubungula kusengaphambili kukusiza:

  • Thuthukisa ukuzinza kokufunda ngokufaka izici ezithombeni ezingase zisetshenziswe abalinganisi ngokwethembeka (ikakhulukazi uma kuhilelekile ukukala/ukubhala ikhodi). [1]

  • Nciphisa umsindo ngokwenza iqiniso elingcolile libukeke njengento imodeli engayihlanganisa ngayo (esikhundleni sokukhumbula izinto zobuciko ezingavamile).

  • Vimbela izindlela zokwehluleka ezithule njengokuvuza kanye nokuqeqesha/ukuphakela ukungalingani (uhlobo olubukeka “lumangalisa” ekuqinisekisweni bese kuba yizitshalo zobuso ekukhiqizweni). [2]

  • Sheshisa ukuphindaphinda ngoba i-repeatable transforms beat notebook spaghetti nsuku zonke zesonto.

Futhi, yilapho "ukusebenza kwemodeli" okuningi kuvela khona. Njengokuthi... ngokumangazayo kakhulu. Ngezinye izikhathi kuzwakala kungafanele, kodwa lokho kuyiqiniso 🙃

Yini eyenza ipayipi elihle lokucubungula i-AI ✅

"Inguqulo enhle" yokucubungula kusengaphambili ivame ukuba nalezi zimfanelo:

  • Iphinde ikhiqizwe : okokufaka okufanayo → okukhiphayo okufanayo (akukho ukungahleleki okuyimfihlakalo ngaphandle kokuthi kube ukwandiswa okuhlosiwe).

  • Ukungaguquguquki kokukhonza isitimela : noma yini oyenzayo ngesikhathi sokuqeqeshwa isetshenziswa ngendlela efanayo ngesikhathi sokuphetha (amapharamitha afanayo afakiwe, amamephu esigaba afanayo, ukulungiselelwa okufanayo kwe-tokenizer, njll.). [2]

  • Ukuphepha kokuvuza : akukho lutho ekuhlolweni/ekuhlolweni oluthonya noma yisiphi sokufaneleka . (Okunye ngalesi sihibe maduze.) [2]

  • Okubonakalayo : ungahlola ukuthi yini eshintshile (izibalo zesici, ukuntuleka, ukubalwa kwesigaba) ngakho ukulungisa amaphutha akulona ubunjiniyela obusekelwe kuma-vibes.

Uma ukucubungula kwakho kusengaphambili kuyinqwaba yamaseli e-notebook abizwa ngokuthi i-final_v7_really_final_ok … uyazi ukuthi kunjani. Kusebenza kuze kube yilapho kungenzeki 😬

Amabhlogo okwakha ayisisekelo okucubungula i-AI kusengaphambili 🧱

Cabanga ngokucubungula kusengaphambili njengeqoqo lamabhlogo wokwakha owahlanganisayo ube yipayipi.

1) Ukuhlanza nokuqinisekisa 🧼

Imisebenzi ejwayelekile:

  • susa okuphindwe kabili

  • phatha amanani angekho (ukulahla, ukusola, noma ukumelela ukuntuleka ngokusobala)

  • sebenzisa izinhlobo, amayunithi, kanye nobubanzi

  • thola okokufaka okungalungile

  • yenza amafomethi ombhalo abe ngokwejwayelekile (isikhala esimhlophe, imithetho yokubeka izinsika, izici ezingavamile ze-Unicode)

Le ngxenye ayikhangi, kodwa ivimbela amaphutha angenangqondo kakhulu. Ngikusho lokho ngothando.

2) Ukufaka ikhodi yedatha yesigaba 🔤

Amamodeli amaningi awakwazi ukusebenzisa ngqo izintambo ezingavuthiwe njenge- "red" noma i-"premium_user" .

Izindlela ezivamile:

  • Ukufaka ikhodi okushisa okukodwa (isigaba → amakholomu amabili) [1]

  • Ukufaka ikhodi okujwayelekile (isigaba → i-ID yenani eliphelele) [1]

Into ebalulekile akukhona muphi umshini wokufaka ikhodi—ukuthi imephu ihlala ihambisana futhi “ayishintshi isimo” phakathi kokuqeqeshwa kanye nokuqagela. Yileyo ndlela ogcina ngayo unomodeli obukeka kahle ungaxhunyiwe ku-inthanethi futhi oziphatha njengomuntu ohlushwayo ku-inthanethi. [2]

3) Ukwelulwa kwezici kanye nokulungiswa kwesimo 📏

Ukukhulisa kubalulekile uma izici ziphila ezindaweni ezahlukene kakhulu.

Ama-classic amabili:

  • Ukumiswa : susa isilinganiso kanye nesikali ku-variance yeyunithi [1]

  • Ukukala okuncane kakhulu : kala isici ngasinye sibe ububanzi obucacisiwe [1]

Ngisho noma usebenzisa amamodeli “avame ukubhekana nalokhu,” ukukala kuvame ukwenza kube lula ukucabanga ngamapayipi—futhi kube nzima ukuwaphula ngengozi.

4) Ubunjiniyela besici (okwaziwa nangokuthi ukukopela okuwusizo) 🧪

Yilapho wenza umsebenzi womodeli ube lula ngokudala amasignali angcono:

  • izilinganiso (ukuchofoza / imibono)

  • amafasitela ajikelezayo (izinsuku zokugcina ze-N)

  • ukubalwa (imicimbi ngomsebenzisi ngamunye)

  • ukuguqulwa kwelogi kokusabalalisa okunemisila esindayo

Kukhona ubuciko lapha. Ngezinye izikhathi uzodala isici, uzizwe uziqhenya… futhi akwenzi lutho. Noma okubi nakakhulu, kubuhlungu. Lokho kuvamile. Unganamatheli ngokomzwelo ezicini - nabo abakuthandi 😅

5) Ukuhlukanisa idatha ngendlela efanele ✂️

Lokhu kuzwakala kusobala kuze kube yilapho kungabonakali:

  • ukuhlukaniswa okungahleliwe kwedatha ye-iid

  • ukuhlukaniswa okusekelwe esikhathini kochungechunge lwesikhathi

  • ukuhlukaniswa okuqoqiwe lapho izinhlangano ziphinda (abasebenzisi, amadivayisi, iziguli)

Futhi okubaluleke kakhulu: hlukanisa ngaphambi kokufaka ukucubungula kwangaphambili okufunda kudatha . Uma isinyathelo sakho sokucubungula kwangaphambili "sifunda" amapharamitha (njengezindlela, amagama, amamephu esigaba), kumele siwafunde ngokuqeqeshwa kuphela. [2]

Ukucubungula kwangaphambili kwe-AI ngohlobo lwedatha: ithebula, umbhalo, izithombe 🎛️

Ukucubungula kusengaphambili kushintsha isimo kuye ngokuthi yini oyiphakelayo imodeli.

Idatha yethebula (amaspredishithi, izingodo, izizindalwazi) 📊

Izinyathelo ezivamile:

  • isu elingekho lenani

  • ukufaka ikhodi ngokwezigaba [1]

  • ukukala amakholomu ezinombolo [1]

  • ukuphathwa okungaphandle (imithetho yesizinda idlula "ukunqunywa okungahleliwe" isikhathi esiningi)

  • izici ezithathwe (ukuhlanganiswa, ukulibaziseka, izibalo ezigoqekayo)

Iseluleko esiwusizo: chaza amaqembu ekholomu ngokucacile (izinombolo vs izigaba vs izihlonzi). Uzokubonga esikhathini esizayo.

Idatha yombhalo (i-NLP) 📝

Ukucubungula umbhalo kusengaphambili kuvame ukufaka:

  • ukwenziwa kwethokheni kube amathokheni/amagama angaphansi

  • ukuguqulwa kube ama-ID okufaka

  • ukugoqa/ukusika

  • ukwakha imaski yokunaka yokuhlanganisa [3]

Umthetho omncane osindisa ubuhlungu: ngokusetha okusekelwe ku-transformer, landela izilungiselelo ze-tokenizer ezilindelekile zemodeli futhi ungazenzi i-freestyle ngaphandle kokuthi unesizathu. I-Freestyle yindlela ogcina ngayo "iyaqeqesha kodwa iyaxaka."

Izithombe (umbono wekhompyutha) 🖼️

Ukucubungula okuvamile:

  • shintsha usayizi/nqampuna ube yizimo ezihambisanayo

  • ukuguqulwa okuqinisekile kokuhlolwa

  • ukuguqulwa okungahleliwe kokukhulisa ukuqeqeshwa (isb., ukunqampuna okungahleliwe) [4]

Into eyodwa abantu abayiphutheli: "ukuguqulwa okungahleliwe" akuyona nje i-vibe - bathatha amasampula amapharamitha njalo lapho bebizwa. Kuhle ekuqeqesheni ukuhlukahluka, kubi kakhulu ekuhloleni uma ukhohlwa ukuvala ukungahleliwe. [4]

Ugibe wonke umuntu awela kulo: ukuvuza kwedatha 🕳️🐍

Ukuvuza kwenzeka lapho ulwazi oluvela kudatha yokuhlola lungena ngokunyenya ekuqeqeshweni—ngokuvamile ngokucubungula kusengaphambili. Kungenza imodeli yakho ibukeke imangalisa ngesikhathi sokuqinisekiswa, bese ikudumaza ezweni langempela.

Amaphethini avamile okuvuza:

  • ukukala kusetshenziswa izibalo zesethi yedatha ephelele (esikhundleni sokuqeqesha kuphela) [2]

  • amamephu esigaba sokwakha kusetshenziswa isitimela+ukuhlolwa ndawonye [2]

  • noma yisiphi se-fit() noma se-fit_transform() "esibona" ​​isethi yokuhlola [2]

Umthetho oyinhloko (olula, ononya, osebenzayo):

  • Noma yini enesinyathelo sokufaneleka kufanele ifaneleke ekuqeqeshweni kuphela.

  • Bese uguqula ukuqinisekiswa/ukuhlola usebenzisa leyo transformer efakiwe. [2]

Futhi uma ufuna ukuthi “kungaba kubi kangakanani?” gut-check: amadokhumenti e-scikit-learn abonisa isibonelo sokuvuza lapho i-oda lokucubungula elingalungile liveza ukunemba okucishe kube ngu -0.76 kuma-targets angahleliwe-bese kwehla ku-~ 0.5 uma ukuvuza sekulungisiwe. Yileyo ndlela ukuvuza okungalungile okungabonakala ngayo. [2]

Ukuqala ukucubungula ngaphambi kokukhiqiza ngaphandle kwesiphithiphithi 🏗️

Amamodeli amaningi ayahluleka ekukhiqizweni hhayi ngoba imodeli "imbi", kodwa ngoba iqiniso lokufakwayo liyashintsha - noma ipayipi lakho liyashintsha.

Ukucubungula kusengaphambili okugxile ekukhiqizeni kuvame ukufaka:

  • Izinto zobuciko ezilondoloziwe (ukumapha kwe-encoder, amapharamitha e-scaler, ukulungiselelwa kwe-tokenizer) ngakho-ke ukuphetha kusebenzisa ukuguqulwa okufanayo okufundiwe [2]

  • Izinkontileka zokufaka eziqinile (amakholomu/izinhlobo/ububanzi obulindelekile)

  • Ukuqapha ukujika kanye nokukhukhuleka , ngoba idatha yokukhiqiza izozulazula [5]

Uma ufuna izincazelo eziqondile: I-Vertex AI Model Monitoring ye-Google ihlukanisa i-skew-serving skew (ukusatshalaliswa kokukhiqiza kuyaphambuka ekuqeqeshweni) kanye ne-inference drift (ukushintsha kokusatshalaliswa kokukhiqiza ngokuhamba kwesikhathi), futhi isekela ukuqapha kokubili izici zesigaba kanye nezezinombolo. [5]

Ngoba izinto ezimangalisayo ziyabiza. Futhi akuzona ezokuzijabulisa.

Ithebula lokuqhathanisa: ukucubungula okuvamile + amathuluzi okuqapha (nokuthi angobani) 🧰

Ithuluzi / umtapo wolwazi Kuhle kakhulu Intengo Kungani kusebenza (kanye nokwethembeka okuncane)
ukucubungula kwangaphambili kwe-scikit Amapayipi e-ML ethebula Mahhala Ama-encoder aqinile + ama-scaler (i-OneHotEncoder, i-StandardScaler, njll.) kanye nokuziphatha okubikezelwayo [1]
Amathokheni obuso obugoqayo Ukulungiselela okokufaka kwe-NLP Mahhala Ikhiqiza ama-ID okufaka kanye nama-masks okunaka njalo kuwo wonke ama-run/amamodeli [3]
i-torchvision iguqula Umbono uguqula + ukwandisa Mahhala Indlela ehlanzekile yokuhlanganisa ukuguqulwa okunqunyiwe nokungahleliwe epayipini elilodwa [4]
Ukuqapha Imodeli ye-Vertex AI Ukutholwa kokukhukhuleka/ukugoba kumkhiqizo Ikhokhelwe (ifu) Ama-monitor afaka ukujika/ukukhukhuleka kanye nezixwayiso lapho imingcele idlula [5]

(Yebo, ithebula lisenemibono. Kodwa okungenani imibono eqotho 😅)

Uhlu lokuhlola lokucubungula olusebenzayo ongalusebenzisa ngempela 📌

Ngaphambi kokuqeqeshwa

  • Chaza iskimu yokufaka (izinhlobo, amayunithi, amabanga avunyelwe)

  • Amanani angekho kanye nezimpinda zokuhlola

  • Hlukanisa idatha ngendlela efanele (ngokungahleliwe / ngokususelwa esikhathini / ngokuqoqwa)

  • Ukulungiswa kwangaphambili kokufaneleka ekuqeqeshweni kuphela ( fit / fit_transform ihlala esitimeleni) [2]

  • Londoloza izinto zobuciko ezisalungiswa kusengaphambili ukuze ukuqagela kukwazi ukuzisebenzisa kabusha [2]

Ngesikhathi sokuqeqeshwa

  • Sebenzisa ukwandiswa okungahleliwe kuphela lapho kufaneleka khona (ngokuvamile ukuqeqeshwa kuhlukaniswa kuphela) [4]

  • Gcina ukuhlolwa kusenesikhathi kucutshungulwa kusengaphambili [4]

  • Landelela izinguquko zokucubungula kwangaphambili njengezinguquko zemodeli (ngoba zikhona)

Ngaphambi kokufakwa

  • Qinisekisa ukuthi ukuphetha kusebenzisa indlela efanayo yokucubungula kanye nezinto zobuciko ezifanayo [2]

  • Setha ukuqapha ukuzulazula/ukugoba (ngisho nokuhlolwa kokusatshalaliswa kwezici eziyisisekelo kuhamba ibanga elide) [5]

Ukucwila okujulile: amaphutha avamile okucubungula kusengaphambili (nokuthi ungawagwema kanjani) 🧯

Iphutha 1: “Ngizolungisa yonke into ngokushesha” 😵

Uma ubala amapharamitha okukala kusethi yedatha ephelele, uvuza ulwazi lokuhlola. Faka esitimeleni, shintsha okusele. [2]

Iphutha 2: izigaba eziya esiphithiphithini 🧩

Uma ukumapha kwesigaba sakho kushintsha phakathi kokuqeqeshwa kanye nokuqagela, imodeli yakho ingawufunda kabi umhlaba buthule. Gcina ukumapha kulungisiwe ngezinto ezigciniwe. [2]

Iphutha 3: ukukhushulwa okungahleliwe kungena ekuhlolweni 🎲

Ukuguqulwa okungahleliwe kuhle kakhulu ekuqeqeshweni, kodwa akufanele "kuvuliwe ngasese" uma uzama ukukala ukusebenza. (Okungahleliwe kusho okungahleliwe.) [4]

Amazwi Okugcina 🧠✨

Ukucubungula kwangaphambili kwe-AI kuwubuciko obuhlelekile bokuguqula iqiniso elingcolile libe okokufaka kwemodeli okuhambisanayo. Kuhlanganisa ukuhlanza, ukufaka ikhodi, ukukala, ukwenza amathokheni, ukuguqulwa kwesithombe, futhi-okubaluleke kakhulu-amapayipi nezinto zobuciko eziphindaphindwayo.

  • Yenza ukucubungula kusengaphambili ngamabomu, hhayi ngokunganaki. [2]

  • Hlukanisa kuqala, shintsha ukulingana ngokuqeqeshwa kuphela, gwema ukuvuza. [2]

  • Sebenzisa ukucubungula kwangaphambili okufanele ngendlela efanele (amathokheni ombhalo, ukuguqulwa kwezithombe). [3][4]

  • Gada ukujika/ukukhukhuleka kokukhiqiza ukuze imodeli yakho ingasheleli kancane kancane ibe yinto engenangqondo. [5]

Futhi uma kwenzeka ubambeke, zibuze:
“Ingabe lesi sinyathelo sokucubungula kusengaphambili sisazoba nengqondo uma ngisiqhuba kusasa kudatha entsha?”
Uma impendulo ithi “uhh… mhlawumbe?”, yilokho okubonayo 😬

Imibuzo Evame Ukubuzwa

Kuyini ukucubungula kwangaphambili kwe-AI, ngamagama alula?

Ukucubungula kwangaphambili kwe-AI kuyisethi yezinyathelo eziphindaphindwayo eziguqula idatha eluhlaza enomsindo, enokuguquguquka okuphezulu ibe okokufaka okuhambisanayo imodeli engafunda kukho. Kungafaka phakathi ukuhlanza, ukuqinisekiswa, ukufaka ikhodi kuzigaba, ukukala amanani ezinombolo, ukwenza umbhalo ube uphawu, kanye nokusebenzisa ukuguqulwa kwesithombe. Umgomo ukuqinisekisa ukuthi ukuqeqeshwa kanye nokuphetha kokukhiqiza kubona "uhlobo olufanayo" lokufaka, ukuze imodeli ingasheleli ekuziphatheni okungalindelekile kamuva.

Kungani ukucubungula kwangaphambili kwe-AI kubaluleke kangaka ekukhiqizeni?

Ukucubungula kusengaphambili kubalulekile ngoba amamodeli azwela ukumelwa kokufakwayo. Uma idatha yokuqeqesha ilinganiswa, ibhalwe ngekhodi, ithokheniwe, noma iguqulwa ngendlela ehlukile kunedatha yokukhiqiza, ungathola ukwehluleka kokungafani kwesitimela/ukukhonza okubukeka kukuhle ungaxhunyiwe ku-inthanethi kodwa kwehluleka buthule ku-inthanethi. Amapayipi aqinile okucubungula kusengaphambili nawo anciphisa umsindo, athuthukise ukuzinza kokufunda, futhi asheshise ukuphindaphinda ngoba awuqaqi i-spaghetti yenotebook.

Ngingakugwema kanjani ukuvuza kwedatha lapho ngicubungula kusengaphambili?

Umthetho olula uyasebenza: noma yini enesinyathelo sokufaneleka kumele ilingane nedatha yokuqeqesha kuphela. Lokho kufaka phakathi ama-scalers, ama-encoder, nama-tokeniser afunda amapharamitha afana nezindlela, amamephu esigaba, noma amagama. Uhlukanisa kuqala, ulingane nesigaba sokuqeqesha, bese uguqula ukuqinisekiswa/ukuhlola usebenzisa i-transformer efakiwe. Ukuvuza kungenza ukuqinisekiswa kubukeke "kuhle ngomlingo" bese kuncipha ekusetshenzisweni kokukhiqiza.

Yiziphi izinyathelo ezivame kakhulu zokucubungula idatha yethebula?

Kudatha yethebula, ipayipi evamile ihlanganisa ukuhlanza nokuqinisekisa (izinhlobo, ububanzi, amanani angekho), ukufaka ikhodi ngezigaba (okushisayo okukodwa noma okujwayelekile), kanye nokukala ngezinombolo (ukuma okujwayelekile noma okungaphansi kobuningi). Amapayipi amaningi engeza ubunjiniyela bezici obuqhutshwa yisizinda njengezilinganiso, amafasitela ajikelezayo, noma ukubalwa. Umkhuba osebenzayo ukuchaza amaqembu ekholomu ngokucacile (izinombolo vs izihlonzi zezigaba vs izihlonzi) ukuze ukuguqulwa kwakho kuhlale kufana.

Ukucubungula kusengaphambili kusebenza kanjani kumamodeli wombhalo?

Ukucubungula umbhalo kusengaphambili ngokuvamile kusho ukwenziwa kwamathokheni kube amathokheni/amagama angaphansi, ukuwaguqula abe ama-ID okufaka, kanye nokuphatha ukugoqa/ukusika ukuze kuhlanganiswe. Ama-workflow amaningi e-transformer nawo adala imaski yokunaka eceleni kwama-ID. Indlela evamile ukusebenzisa ukucushwa kwe-tokenizer okulindelekile kwemodeli kunokwenza izinto ngendlela entsha, ngoba umehluko omncane kuzilungiselelo ze-tokeniser ungaholela ekutheni "iqeqeshe kodwa iziphatha ngendlela engalindelekile".

Yini ehlukile ngokucubungula izithombe zokufunda komshini?

Ukucubungula isithombe kusengaphambili kuvame ukuqinisekisa ukuma okuhambisanayo kanye nokuphathwa kwamaphikseli: ukushintsha usayizi/ukunqampuna, ukwenziwa kube ngokwejwayelekile, kanye nokwahlukana okucacile phakathi kokuguqulwa okunqunyiwe kanye nokuguqulwa okungahleliwe. Ukuze kuhlolwe, ukuguqulwa kufanele kube okunqunyiwe ukuze izilinganiso zifane. Ekuqeqeshweni, ukwandiswa okungahleliwe (njengezitshalo ezingahleliwe) kungathuthukisa ukuqina, kodwa ukungahleliwe kumele kufakwe ngamabomu ekuhlukanisweni kokuqeqeshwa, hhayi ngengozi kushiywe ngesikhathi sokuhlolwa.

Yini eyenza ipayipi elisebenza ngaphambi kokucubungula libe “lihle” esikhundleni sokuba libuthakathaka?

Ipayipi elihle lokucubungula i-AI liyakwazi ukuphinda likhiqizwe, liphephile ukuvuza, futhi liyabonwa. I-Reproducible isho ukuthi ukufaka okufanayo kukhiqiza umphumela ofanayo ngaphandle kokuthi ukungahleliwe kuwukwandisa ngamabomu. I-Repeace-Safe isho ukuthi izinyathelo zokulingana azikaze zithinte ukuqinisekiswa/ukuhlolwa. I-Observable isho ukuthi ungahlola izibalo ezifana nokuntuleka, ukubalwa kwezigaba, kanye nokusatshalaliswa kwezici ngakho ukulungisa amaphutha kusekelwe ebufakazini, hhayi ekuzizweni kwamathumbu. Amapayipi anqoba ukulandelana kwezincwadi zamabhuku ezingahleliwe njalo.

Ngingakugcina kanjani ukuqeqeshwa kanye nokucubungula kusengaphambili kuhambisana?

Isihluthulelo ukusebenzisa kabusha izinto ezifanayo ezifundiwe ngesikhathi sokuphetha: amapharamitha wesikali, ukumepha kwekhodi, kanye nokulungiselelwa kwe-tokenizer. Ufuna futhi inkontileka yokufaka (amakholomu alindelekile, izinhlobo, kanye nobubanzi) ukuze idatha yokukhiqiza ingakwazi ukuzulazula buthule ibe yizimo ezingavumelekile. Ukuvumelana akukhona nje "ukwenza izinyathelo ezifanayo" - "ukwenza izinyathelo ezifanayo ngamapharamitha afanayo namamephu."

Ngingaziqapha kanjani izinkinga zokucubungula kwangaphambili njengokukhukhuleka kanye nokugoba ngokuhamba kwesikhathi?

Ngisho noma kunendlela eqinile, idatha yokukhiqiza iyashintsha. Indlela evamile ukuqapha izinguquko zokusatshalaliswa kwesici nokuxwayisa ngokuchezuka kokunikezwa koqeqesho (ukukhiqiza kuyaphambuka ekuqeqeshweni) kanye nokushintshashintsha kokucabanga (izinguquko zokukhiqiza ngokuhamba kwesikhathi). Ukuqapha kungaba lula (ukuhlolwa kokusabalalisa okuyisisekelo) noma ukuphathwa (njengokuqapha i-Vertex AI Model). Umgomo ukubamba ukushintsha kokufaka kusenesikhathi - ngaphambi kokuba kunciphise kancane ukusebenza kwemodeli.
