Ni gute AI ihanura Impinduka?

Ubuhanga bwo gukora imibonano mpuzabitsina bushobora kubona imiterere y'amaso yambaye ubusa, bukagaragaza ibimenyetso bisa n'urusaku mu ntangiriro. Bikozwe neza, bihindura imyitwarire mibi mu kureba kure - kugurisha mu kwezi gutaha, ejo hazaza, bizakorwa mu mpera z'iki gihembwe. Bikozwe nabi, ni ukwiyizera. Muri iyi nyandiko, tuzareba uburyo bwo gutegura imiterere ya AI, aho intsinzi ziva, n'uburyo bwo kwirinda gushukwa n'imbonerahamwe nziza. Nzabikomeza mu buryo bufatika, hamwe n'ibihe bike byo kuganiraho no kwiyongera kw'amaso rimwe na rimwe 🙃.

Ingingo ushobora gukunda gusoma nyuma y'iyi:

🔗 Uburyo bwo gupima imikorere ya AI
Ibipimo by'ingenzi byo gusuzuma ubunyangamugayo, imikorere myiza, n'ubwizerwe bwa sisitemu za AI.

🔗 Uburyo bwo kuvugana n'ubutasi (AI)
Inama z'ingirakamaro zo kuvugana na AI kugira ngo kunoze uburyo bwo gusubiza.

🔗 Ni iki gitera imbaraga mu buhanga bwa AI?
Gusobanura neza uburyo ubutumwa butuma umuntu akoresha ikoranabuhanga bugira ingaruka ku myitwarire y’ubukorano n’umusaruro wabwo.

🔗 Gushyira ibirango ku makuru ya AI ni iki?
Intangiriro yo gushyira amazina ku makuru neza mu buryo bwo guhugura imashini zo kwigira.

Ni iki gituma habaho isuzuma ryiza ry'impinduka za AI ✅

Iyo abantu babaza uburyo AI ihanura Ingendo, akenshi baba bashaka kuvuga: ni gute ihanura ikintu kitazwi neza ariko kigaruka. Iteganyagihe ryiza rifite ibintu bike birambiranye ariko byiza:

• Amakuru afite ikimenyetso - ntushobora gukamura umutobe w'icunga mu ibuye. Ukeneye indangagaciro n'aho ibintu biherereye mbere.

• Ibintu bigaragaza ukuri - ibihe by'umwaka, iminsi mikuru, poromosiyo, imiterere rusange, ndetse n'ikirere. Si byose, ahubwo ni ibyo bikurura urushinge rwawe gusa.

• Uburyo bujyanye n'isaha - uburyo bwo kumenya igihe kandi bwubahiriza gahunda, icyuho, no guhindagurika.

• Isuzuma rigaragaza uko ibintu bizagenda - ibizamini byerekana uko uzabiteganya mu by'ukuri. Nta kureba [2].

• Gukurikirana impinduka - isi irahinduka; icyitegererezo cyawe nacyo kigomba guhinduka [5].

Ayo ni amagufwa. Ibisigaye ni imitsi, imitsi, na kafeyine nkeya.

Umuyoboro w'ingenzi: uburyo AI ihanura Impinduka kuva ku makuru fatizo kugeza ku iteganyagihe 🧪

1. Gukusanya no guhuza amakuru
   Huza urutonde rw'ibikenewe hamwe n'ibimenyetso byo hanze. Inkomoko zisanzwe: katalogu z'ibicuruzwa, amafaranga yakoreshejwe mu kwamamaza, ibiciro, ibipimo bya macro, n'ibyabaye. Huza ibihe, tunganya agaciro kabuze, shyira ibipimo mu buryo busanzwe. Ntabwo ari byiza ariko ni ingenzi.

2. Ibiranga injeniyeri
   Gukora ibirarane, uburyo bwo kuzunguruka, kwimura quantiles, ibendera ry'umunsi w'icyumweru, n'ibipimo byihariye by'aho ibintu biherereye. Kugira ngo hakosorwe ibihe by'umwaka, abahanga benshi bagabanya uruhererekane mu bice by'ingenzi, ibihe by'umwaka, n'ibisigaye mbere yo gukora icyitegererezo; gahunda ya X-13 y'Ikigo cy'Ibarura Rusange cya Amerika niyo shingiro ry'uburyo n'impamvu ibi bikorwa [1].

3. Hitamo umuryango w'icyitegererezo.
   Ufite indobo eshatu nini:

• Imibare ya kera : ARIMA, ETS, state-space/Kalman. Irasobanuka kandi yihuse.

• Kwiga imashini : kongera ubunini bw'amashyamba, amashyamba adasanzwe afite ibintu bikoresha igihe. Bishobora guhinduka mu buryo butandukanye.

• Kwiga byimbitse : LSTM, CNN z'igihe gito, Transformers. Ni ingirakamaro iyo ufite amakuru menshi n'imiterere igoye.

4. Gusuzuma inyuma neza.
   Isuzuma ry'igihe rikoresha inkomoko ihindagurika kugira ngo utigera witoza ku hazaza mu gihe ugerageza ibyahise. Ni itandukaniro riri hagati y'ukuri n'ibitekerezo by'ibyifuzo [2].

5. Guteganya, gupima ibitazwi, no kohereza
   ibizamini byo kugaruka hamwe n'ibihe, gukurikirana amakosa, no kongera kwitoza uko isi igenda ihinduka. Serivisi zicungwa zikunze gupima ubuziranenge bw'ibipimo (urugero, MAPE, WAPE, MASE) no gusuzuma amadirishya inyuma, ibyo bigatuma imiyoborere n'amadashibodi byoroha [3].

Inkuru y'intambara ngufi: mu imurikagurisha rimwe, twamaze umunsi w'inyongera ku bintu bya kalendari (iminsi mikuru yo mu karere + ibendera rya promosiyo) kandi twagabanyije amakosa yo hakiri kare cyane kuruta guhinduranya moderi. Imiterere myiza y'imideli ni nshya - insanganyamatsiko uzongera kubona.

Imbonerahamwe yo kugereranya: ibikoresho bifasha AI guhanura Impinduka 🧰

Kutagira inenge nkana - ameza nyayo afite imico mike y'abantu.

Yego, imvugo ntiringana. Ubwo ni bwo buzima busanzwe.

Ubwubatsi bw'ibintu butuma urushinge rugenda 🧩

Igisubizo cy'ingirakamaro cyoroshye ku buryo AI Predict Trends ari iyi: duhindura uruhererekane rw'ibiganiro mu mbonerahamwe y'amasomo igenzurwa yibuka igihe. Hari intambwe nke zo gukora:

• Ibirarane n'amadirishya : harimo y[t-1], y[t-7], y[t-28], hamwe n'uburyo bwo gusimbuka na std dev. Bifata umuvuduko n'ubudahangarwa.

• Ibimenyetso by'ibihe : ukwezi, icyumweru, umunsi w'icyumweru, isaha y'umunsi. Amagambo ane atanga imirongo y'ibihe igororotse.

• Kalendari n'ibikorwa : iminsi mikuru, gutangiza ibicuruzwa, impinduka z'ibiciro, poromosiyo. Ingaruka z'iminsi mikuru nk'iya Prophet ni ibintu bifite ibyabanje.

• Gusenyuka : gukuramo igice cy’igihe hanyuma ugaragaze igisigaye iyo imiterere ikomeye; X-13 ni ishingiro ryageragejwe neza kuri ibi [1].

• Isubira inyuma ry'inyuma : ikirere, indexes macro, pageviews, inyungu zo gushakisha.

• Amabwiriza yo gukoresha uburyo bwo gukorana : imbuga zoroshye nka promo_flag × day_of_week. Ni ibintu bidasobanutse neza ariko akenshi birakora.

Niba ufite urukurikirane rwinshi rufitanye isano - urugero nka SKU ibihumbi - ushobora gukusanya amakuru kuri zo ukoresheje moderi zishingiye ku nzego cyangwa ku rwego rw'isi. Mu by'ukuri, moderi yongereye ubunini ku isi ifite imiterere ijyanye n'igihe akenshi irenza uburemere bwayo.

Guhitamo imiryango y'icyitegererezo: imirwano y'ubucuti 🤼♀️

• ARIMA/ETS
  : imiterere y'ibanze isobanutse, yihuta kandi ikomeye. Ibibi: gutunganya buri gice bishobora kugorana ku rugero runaka. Guhuza ibice by'imikorere bishobora gufasha kugaragaza imiterere, ariko ntugategereze ibitangaza.

• byo kongera imbaraga
  : ikora neza ku miterere y'amakuru, ikomeye kugeza ku majwi avanze, ikora neza hamwe n'amakuru menshi ajyanye nayo. Ibibi: ugomba gusesengura neza imiterere y'igihe no kubahiriza impamvu.

• Kwiga byimbitse
  Ibyiza: ifata imiterere idahuje n'umurongo n'uruhererekane. Ibibi: ikeneye amakuru menshi, iragoye kuyakosora. Iyo ufite amateka menshi cyangwa amateka maremare, irashobora kugaragara; bitabaye ibyo, ni imodoka ya siporo mu gihe cy'umuvuduko mwinshi.

• Ibyiciro by’ibihuzwa n’ibindi.
  Reka tuvugishe ukuri, gushyiramo ibikoresho by’igihe kimwe hamwe n’ibikoresho bitera imbaraga kandi ukabivanga na LSTM yoroheje ni ikintu gitangaje. Nasubiye inyuma ku "buziranenge bwa moderi imwe" inshuro nyinshi kuruta uko nemera.

Impamvu vs isano: kora witonze 🧭

Kuba imirongo ibiri ihuzwa ntibivuze ko umwe uyobora undi. Gushingira ku mpamvu za Granger bipima niba kongeramo umushoferi ukwiye kunoza ubuhanuzi bw'intego, bitewe n'amateka yayo. Ni ingirakamaro mu guhanura munsi y'ibitekerezo bya autoregression, ntabwo ari filosofi - itandukaniro rito ariko ry'ingenzi [4].

Mu gukora, uracyagenzura neza ukoresheje ubumenyi bw'urubuga. Urugero: ingaruka zo mu minsi y'icyumweru ni ingenzi ku bacuruzi, ariko kongeramo amajwi yo mu cyumweru gishize bishobora kuba ibidashoboka niba amafaranga akoreshwa ari muri urwo rwego.

Gusuzuma inyuma n'ibipimo: aho amakosa menshi yihisha 🔍

Kugira ngo usuzume uburyo AI Predict Trends igaragara mu buryo bufatika, gana uko uzateganya mu gasozi:

• Guhindura inkomoko y'aho ibintu biherereye : gusesengura amakuru yabanje no guhanura igice gikurikira. Ibi byubaha gahunda y'igihe kandi birinda gusohoka mu gihe kizaza [2].

• Ibipimo by'amakosa : hitamo ibihuye n'ibyemezo byawe. Ibipimo by'ijanisha nka MAPE birakunzwe, ariko ibipimo by'uburemere (WAPE) cyangwa ibidafite igipimo (MASE) akenshi byitwara neza kuri portfolios na aggregates [3].

• Intera z'ibiteganyijwe : ntutange ingingo gusa. Vuga ibintu utazi neza. Abayobozi ntibakunze gukunda urwego rw'ibikorwa, ariko bakunda ibintu bike bitunguranye.

Akantu gato: iyo ibintu bishobora kuba zeru, ibipimo by'ijanisha biratangaje. Hitamo amakosa arambuye cyangwa akozwe mu gipimo, cyangwa ongeramo amakosa make - komeza ubyumve neza.

Gutembera bibaho: kumenya no guhuza n'impinduka 🌊

Isoko rihinduka, ibyo abantu bakunda bigenda bihindagurika, imyaka y'ibikoresho. Guhindagurika kw'ibitekerezo ni cyo kintu kigaragara mu gihe isano iri hagati y'ibikubiye mu bushakashatsi n'intego ihinduka. Ushobora gukurikirana uko ibintu bigenda bihindagurika ukoresheje ibizamini by'ibarurishamibare, amakosa yo gusimbuka kw'amadirishya, cyangwa kugenzura uko amakuru akwirakwizwa. Hanyuma hitamo ingamba: igihe gito cyo guhugura, kongera guhugura buri gihe, cyangwa uburyo bwo guhindura ibintu buvugururwa kuri interineti. Ubushakashatsi bw'aho hantu bwerekana ubwoko bwinshi bw'uburyo ibintu bigenda bihinduka na politiki yo guhindura ibintu; nta politiki imwe ijyanye n'ibyo byose [5].

Igitabo cy'imikino gifatika: shyiraho uburyo bwo gutanga amakuru ku makosa y'iteganyagihe, ongera umenyere gahunda, kandi ukomeze gutegura uko ibintu bizagenda. Ntabwo ari byiza cyane - bigira ingaruka nziza cyane.

Ibisobanuro: gufungura agasanduku k'umukara utagaciyemo 🔦

Abafatanyabikorwa bibaza impamvu iteganyagihe ryazamutse. Birumvikana. Ibikoresho byo kudatekereza ku iteganyagihe nka SHAP bishyira iteganyagihe ku bintu mu buryo bushingiye ku nyigisho, bigufasha kureba niba ibihe, igiciro, cyangwa imiterere y’imenyekanisha ari byo byatumye umubare uba. Ntabwo bizagaragaza ko ari impamvu, ariko binoza icyizere no gukosora amakosa.

Mu igerageza ryanjye bwite, ibihe by'umwaka n'ibipimo bya promosiyo bikunze kwibanda ku bipimo by'ubucuruzi mu buryo bugufi, mu gihe iby'uburebure bihinduka bikajya ku bipimo bya macro. Ibipimo byawe bizahinduka - neza.

Cloud & MLOps: iteganyagihe ry'ubwikorezi nta kaseti y'imiyoboro 🚚

Niba ukunda urubuga rucungwa:

• Google Vertex AI Forecast itanga uburyo bwo gukoresha igihe, gukoresha AutoML forecasting, backtest, no gukoresha endpoints. Ikora neza kandi hamwe n'amakuru agezweho.

• Amazon Forecast yibanda ku ikoreshwa ryagutse, hamwe n'ibipimo bisanzwe byo gusuzuma no gusuzuma neza ushobora gukoresha API, bifasha mu miyoborere no mu miyoboro y'amakuru [3].
