Kugabanya Ibipimo
Kugabanya ibipimo bigabanya amakuru kuva kumurongo (ibiranga) kugeza kuri bike mugihe ukomeza imiterere yingenzi.
Incamake
It fights the 'curse of dimensionality,' speeds up models, and lets you actually visualize complex data in 2D or 3D.
Kwibira cyane
Imibare nyayo ikunze kugira amagana cyangwa ibihumbi biranga: buri pigiseli mumashusho, buri jambo mumagambo, buri sensor kumashini. Muri ibyo bibanza biri hejuru cyane, ingingo zamakuru ziba nke kandi zitandukanijwe, gupima intera bigenda byizerwa, kandi moderi ikunda urusaku rwinshi. Uyu ni umuvumo wo gupima. Kugabanya ibipimo byerekana amakarita mubipimo bike cyane mugihe ubungabunga umubano usobanutse. PCA ibikora neza mugushakisha icyerekezo cyo gutandukana cyane. t-SNE na UMAP ntabwo ari umurongo kandi ni indashyikirwa muguhishura cluster yo kubona amashusho. Kugabanya ibipimo bikuraho ibintu birenze urugero cyangwa urusaku, bigabanya kwibuka no kubara, kandi bikunze kunoza icyerekezo cyo hasi cyerekana neza kuko hari ibimenyetso bike bidafite aho bihuriye no kubyitiranya.
Ubushishozi
PCA ikora mukubara covariance yibiranga no gushakisha eigenvectors, 'ibyingenzi nyamukuru,' iyo ngingo yerekeza kumyerekezo itandukanye. Urabika ibice bike byambere hamwe namakuru yimishinga kuri bo, ukuraho icyerekezo gito-cyerekezo ahanini ari urusaku. t-SNE na UMAP ahubwo icyitegererezo cyumubano wabaturanyi: bagerageza kugumana ingingo zegeranye murwego rwo hejuru hafi yikarita yo hasi. UMAP yubaka igishushanyo cyibintu byegeranye, bigatuma byihuta kuruta t-SNE kandi byiza mukubungabunga imiterere yagutse yisi.

Ejo hazaza ho Kugabanya Ibipimo
Kugabanya ibipimo ni intambwe isanzwe imbere mumiyoboro minini ya AI aho kuba umurimo wihariye. UMAP yahindutse muburyo budasanzwe bwo gushakisha ibyashizwe mu ndimi nini n’icyerekezo, aho abajenjeri bategura ibipimo ibihumbi mu ikarita ya 2D kugirango barebe ibyo icyitegererezo cyize. Witegereze kwishyira hamwe gukomeye hamwe nubushakashatsi bwihuse, byihuse GPU yihutisha gushyira mubikorwa imibare yumurongo wa miliyari, hamwe no gukoresha cyane mubikorwa byo gusobanura, aho abashakashatsi bagabanya ibikorwa byimbere byimbere kugirango basobanukirwe kandi bakosore imyitwarire yabyo.

What is Dimensionality Reduction?
Kugabanya ibipimo bigabanya amakuru kuva kumurongo (ibiranga) kugeza kuri bike mugihe ukomeza imiterere yingenzi. Irwanya 'umuvumo wuburinganire,' yihutisha moderi, kandi igufasha mubyukuri kwiyumvisha amakuru akomeye muri 2D cyangwa 3D.
'Umuvumo wo gupima' ni iki?
Mumwanya muremure cyane, ingingo zikwirakwira kure kandi ingamba zintera ziracika, kuburyo moderi irwana no gushakisha imiterere kandi ikunda gukabya.
Nigute PCA ihitamo icyerekezo ugomba gukurikiza?
PCA isanga ibice byingenzi, amashoka yo gutandukana cyane, kandi ikomeza hejuru kuko itwara amakuru menshi.
Kuki PCA yitwa 'umurongo'?
Buri kintu cyingenzi kigizwe numurongo uhuza ibintu byumwimerere, PCA rero ntishobora gufata umurongo uhetamye, utari umurongo nkuko t-SNE cyangwa UMAP ishobora.
Niki t-SNE na UMAP nibyiza cyane?
Byombi nubuhanga butari umurongo butuma ingingo zegeranye hafi yikarita ntoya, bigatuma cluster igaragara muri 2D cyangwa 3D.
