None se, ibikora ite? ✅

Iyo abantu babaza bati "How does AI Learn?" , akenshi baba bashaka kuvuga bati: ni gute moderi ziba ingirakamaro aho kuba ibikinisho by'imibare bigezweho gusa. Igisubizo ni resept:

  • Intego isobanutse neza - imikorere yo gutakaza isobanura icyo "icyiza" bivuze. [1]

  • Amakuru y’ubuziranenge - atandukanye, asukuye, kandi afite akamaro. Ubwinshi burafasha; ubwoko burafasha cyane. [1]

  • Gutunganya neza ibintu mu buryo buhamye - kumanuka kw'ibara ry'umuraba hamwe n'amayeri yo kwirinda kunyeganyega kuva ku rutare. [1], [2]

  • Guhuza amakuru - intsinzi ku makuru mashya, ntabwo ari imyitozo gusa. [1]

  • Imirongo y'ibitekerezo - isuzuma, isesengura ry'amakosa, no gusubiramo. [2], [3]

  • Umutekano n'ubwirinzi - ibyuma birinda, ibizamini, n'inyandiko kugira ngo bitaba akajagari. [4]

Kugira ngo ubone ishingiro ryoroshye, inyandiko isanzwe yo kwigiraho mu buryo bwimbitse, inyandiko z'amasomo zinogeye amaso, n'amasomo yo kwihuta akubiyemo ibintu by'ingenzi bitagutera kuzuyaza mu bimenyetso. [1]–[3]

Ni gute AI yiga? Igisubizo kigufi mu Cyongereza cyoroheje ✍️

Icyitegererezo cya AI gitangirana n'agaciro ka parametero kadasanzwe. Gitanga ubuhanuzi. Ubona icyo gitekerezo gitsinzwe . Hanyuma ukoresha ibyo bipimo kugira ngo ugabanye igihombo ukoresheje gradients . Subiramo iki gikoresho mu ngero nyinshi kugeza igihe icyitegererezo kiretse gutera imbere (cyangwa ubuze ibyo kurya). Icyo ni cyo gikoresho cyo guhugura mu guhumeka kumwe. [1], [2]

Niba ushaka kumenya neza kurushaho, reba ibice bivuga ku kumanuka kw'ibara ry'umukara n'ishusho y'umukara hepfo. Kugira ngo ubone amakuru yihuse kandi asobanutse neza, amasomo magufi na laboratwari biraboneka cyane. [2], [3]

Ibintu by'ibanze: amakuru, intego, kunoza 🧩

  • Amakuru : Ibikubiye mu makuru (x) n'intego (y). Uko amakuru arushaho kuba manini kandi asukuye, niko amahirwe yawe yo kuyashyira mu bikorwa aba manini. Gukusanya amakuru ntabwo ari byiza cyane, ariko ni intwari idashimishije. [1]

  • Icyitegererezo : Umumaro (f_\theta(x)) ufite ibipimo (\theta). Imiyoboro y'imitsi ni imirundo y'ibice byoroshye bihurira mu buryo bugoye—amatafari ya Lego, ariko arushaho kuba make. [1]

  • Intego : Igihombo (L(f_\theta(x), y)) gipima ikosa. Ingero: ikosa ry’inyuma (regression) na cross-entropy (ishyirwa mu byiciro). [1]

  • Gukoresha neza : Koresha (stochastic) gradient descent kugira ngo uvugurure ibipimo: (\theta \leftarrow \theta - \eta \nabla_\theta L). Igipimo cyo kwiga (\eta): kinini cyane kandi ugenda uzenguruka; gito cyane kandi urara usinziriye iteka ryose. [2]

Kugira ngo hamenyekane neza imikorere yo gutakaza no kunoza, inyandiko zisanzwe ku mayeri yo gutoza n'ingorane ni nziza cyane. [2]

Kwiga bigenzurwa: Iga ku ngero zanditseho amazina 🎯

Igitekerezo : Erekana ingero ebyiri z'ibisubizo n'ibisubizo nyabyo. Ingero yiga ikarita (x \iburyo y).

  • Imirimo isanzwe : gushyira amashusho mu byiciro, gusesengura amarangamutima, guhanura imbonerahamwe, kumenya imvugo.

  • Ibihombo bisanzwe : cross-entropy yo gushyira mu byiciro, ikosa ry’ikigereranyo cya kare mu gusubira inyuma. [1]

  • Ingaruka mbi : urusaku rw'ibirango, ubusumbane mu byiciro, gusohora amakuru.

  • Ibikosorwa : ingero z’amatsinda, igihombo gikomeye, gukosora, no gukusanya amakuru atandukanye. [1], [2]

Hashingiwe ku bipimo ngenderwaho n'ibikorwa byo gutanga umusaruro mu myaka myinshi, imyigire igenzurwa iracyari yoroshye kuko ibisubizo biteganyijwe kandi ibipimo byoroshye. [1], [3]

Kwiga udafite igenzura n'igenzura ubwawe: menya imiterere y'amakuru 🔍

Unsupervised yiga imiterere idafite ibirango.

  • Gushyira hamwe : gushyira hamwe ingingo zisa—k-means biroroshye kandi bitangaje kugira akamaro.

  • Kugabanya ingano : gukanda amakuru mu cyerekezo cy'ingenzi—PCA ni igikoresho cy'irembo.

  • Ubucucike/uburyo bwo gushushanya : menya uburyo amakuru akwirakwizwa ubwabwo. [1]

yigenzura ubwayo : moderi zikora ubugenzuzi bwazo bwite (guhanura hifashishijwe ikoranabuhanga, kwiga bivuguruzanya), bigufasha kwimenyereza amakuru adafite ibirango hanyuma ukayakosora nyuma. [1]

Kwiga bikomeza: kwiga ubikora kandi ukabona ibitekerezo 🕹️

Umukozi akorana n'ibidukikije , agahabwa ibihembo , kandi akiga politiki mu gutanga ibihembo by'igihe kirekire.

  • Ingingo z'ingenzi : imiterere, igikorwa, igihembo, politiki, imikorere y'agaciro.

  • Algorithme : Kwiga Q, imiterere ya politiki, umukinnyi n'umusesenguzi.

  • Gushakisha cyangwa gukoresha nabi : gerageza ibintu bishya cyangwa ukoreshe ibigufasha.

  • Gutanga inguzanyo : ni ikihe gikorwa cyateje ingaruka?

Ibitekerezo by'abantu bishobora kuyobora imyitozo iyo ibihembo bidafite ishingiro—urwego cyangwa ibyo umuntu akunda bifasha mu guhindura imyitwarire hatabayeho kwandika ibihembo bitunganye. [5]

Kwiga byimbitse, guhagarara inyuma, no kumanuka mu buryo bw'indorerwamo - umutima utera cyane 🫀

Imiyoboro y'ubwonko ni imiterere y'imikorere yoroshye. Kugira ngo bige, bishingiye ku gukwirakwiza inyuma :

  1. Inzira yo gusimbuka : kubara ibiteganyijwe uhereye ku byinjijwe.

  2. Igihombo : pima ikosa hagati y'ibyahanuwe n'intego.

  3. Gusubira inyuma : koresha itegeko ry'uruhererekane kugira ngo ubare gradients z'igihombo wrt kuri buri parameter.

  4. Ivugurura : hindura ibipimo ukoresheje igikoresho gifasha mu gupima.

Uburyo butandukanye nka momentum, RMSProp, na Adam butuma imyitozo idahindagurika cyane. Uburyo bwo kuvugurura ibintu nk'ubureka ishuri , kwangirika kw'ibiro , no guhagarika imyitozo hakiri kare bifasha abantu gukoresha uburyo bworoshye aho gufata mu mutwe. [1], [2]

Transformers n'uburyo bwo kwita ku bandi: impamvu moderi zigezweho zumva zimeze nk'izifite ubwenge 🧠✨

Transformers zasimbuye uburyo bwinshi bwo gusubiramo mu rurimi no mu buryo bwo kureba. Amayeri y'ingenzi ni ukwiyitaho , bituma moderi ipima ibice bitandukanye by'ibyo yinjiza bitewe n'aho iherereye. Uburyo bwo gusesengura imiterere y'aho ibintu biherereye bukora ku buryo butandukanye, naho uburyo bwo kwita ku mitwe myinshi bugatuma moderi yibanda ku mibanire itandukanye icyarimwe. Kwagura - amakuru atandukanye, ibipimo byinshi, amahugurwa maremare - akenshi birafasha, hamwe no kugabanya inyungu no kuzamuka kw'ibiciro. [1], [2]

Guhuza ibintu byose, gukabya, n'imbyino ishingiye ku bias-variance 🩰

Umudeli ashobora kuryoha imyitozo ariko akananirwa mu buzima busanzwe.

  • Gushyiramo ibintu byinshi : gufata mu mutwe urusaku. Ikosa ryo gutoza rigabanutse, ikosa ryo kugerageza rizamuka.

  • Igipimo cyo hasi : biroroshye cyane; ikimenyetso cyabuze.

  • Ubusumbane hagati y’ibice bibiri n’ibindi : ubusumbane bugabanya ubusumbane ariko bushobora kongera ubusumbane.

Uburyo bwo gushyira mu bikorwa neza ibintu muri rusange:

  • Amakuru menshi atandukanye - amasoko atandukanye, domaine, n'ibibazo bitandukanye.

  • Guhindura imikorere - kureka ishuri, kwangirika k'ibiro, kongera amakuru.

  • Kwemeza neza - ibizamini bisukuye, kwemeza amakuru mato.

  • Gukurikirana ihindagurika ry'amakuru - ikwirakwizwa ry'amakuru yawe rizahinduka uko igihe kigenda gihita.

Imyitozo yo kumenya ingaruka mbi ibivuga nk'ibikorwa by'ubuzima bwose - imiyoborere, ikarita, ibipimo, n'imicungire - ntabwo ari urutonde rw'ibintu biteganyijwe rimwe gusa. [4]

Ibipimo by'ingenzi: uburyo tuzi ko kwiga byagenze 📈

  • Ishyirwa mu byiciro : ubunyangamugayo, ubunyangamugayo, kwibuka, F1, ROC AUC. Amakuru adahuje asaba ko habaho imirongo yo kwibuka neza. [3]

  • Gusubira inyuma : MSE, MAE, (R^2). [1]

  • Urutonde/gusubiramo : MAP, NDCG, recall@K. [1]

  • Ingero zitanga umusaruro : urujijo (ururimi), BLEU/ROUGE/CIDEr (inyandiko), amanota ashingiye kuri CLIP (ingero nyinshi), n'isuzumabumenyi ry'abantu. [1], [3]

Hitamo ibipimo bihuye n'ingaruka z'umukoresha. Igabanuka rito ry'ubunyangamugayo rishobora kuba nta kamaro niba ikiguzi nyacyo ari cyo kintu cyiza. [3]
