Imiyoboro ya Neural
Umuyoboro wa neural ni imashini yiga imashini ikozwe mubikorwa byimibare ihujwe hamwe nibipimo bishobora guhinduka.
Incamake
Imirongo ihindura ibyinjira mubisohoka, kandi imyitozo ihindura ibyo bipimo kugirango tunoze imikorere kumugambi wahisemo.
Ibyingenzi byingenzi
- Ibiro no kubogama byizwe ibipimo; ibikorwa byo gukora bihindura ibisubizo hagati.
- Backpropagation ibara gradients ikoreshwa na optimizer.
- Gukora imbere ntabwo bihita bishoboka cyangwa ibisobanuro.
Kwibira cyane
Shingiro ya neuron yibanze ihuza indangagaciro ukoresheje uburemere, yongeraho kubogama, kandi ikoresha ibikorwa. Ibipimo bigenzura uburyo buri cyinjira gitanga umusanzu. Kubogama bihindura ibisubizo. Igikorwa kidafite umurongo kireka ibice byerekana umubano urwego rwibikorwa byumurongo bidashoboka. Kurugero, ibikorwa bya ReLU bisubiza zeru kubintu byinjiza nabi kandi bigasiga ibitekerezo byiza bidahindutse. Imiyoboro irashobora gukoresha ibikorwa bitandukanye mubice bitandukanye. Ibisohoka byatoranijwe kugirango bihuze n'inshingano: guhanura mubare ntibisobanurwa kimwe n'amanota y'ibyiciro bishoboka. Mugihe cyamahugurwa, imikorere yigihombo igereranya ibisohoka nibisubizo byifuzwa. Backpropagation ikoresha urunigi kugirango ibare uburyo ibipimo bigira ingaruka kubihombo. Optimizer noneho ikoresha ayo makuru kugirango ivugurure ibipimo. Backpropagation ibara gradients; ntabwo ari garanti yerekana ko icyitegererezo kizabona igisubizo cyiza gishoboka cyangwa rusange muri rusange. Kugereranya ubwonko ni bike. Neuron artificiel ni imibare ikuramo, kandi urusobe rwatsinze ntabwo ari gihamya yubwenge busa numuntu. Umuyoboro munini urashobora kwerekana umubano utoroshye, ariko birashobora kandi gutwara amafaranga menshi kugirango ukore, uhuze imiterere idafite aho ihuriye, cyangwa binaniranye mugihe ibintu bihindutse. Gereranya na baseline yoroshye kandi ugerageze kuburorero hanze yamakuru yamahugurwa.
Ubushishozi
Hatariho ibikorwa bidafite umurongo hagati yibice, guhimba umurongo uhinduka biracyari umurongo. Ongeraho ibice byonyine ntabwo byashiraho ubushobozi bwo kwerekana imiterere isanzwe ishakishwa numuyoboro udasanzwe.
Kubara neuron imwe
- Koresha inyongeramusaruro ebyiri, 0.8 na 0.5, ufite uburemere 0,6 na -0.4 hamwe no kubogama kwa 0.1.
- Amafaranga aremereye ni (0.8 × 0,6) + (0.5 × -0.4) + 0.1 = 0.38.
- ReLU isubiza 0.38. Niba iyakabiri yinjiye ihindutse kuri 1.5, igiteranyo gihinduka -0.02 na ReLU igasubiza 0.
Iyi mibare ishushanya nimwe ihinduka imbere murusobe. Agaciro 0.38 nigikorwa, ntabwo 38% bisaba ikizere.
Ingaruka z'Ingamba
Ibyemezo bisobanutse
Iragufasha gutandukanya ibyifuzo bya tekiniki bisobanutse nururimi rwo kwamamaza.
Igiciro na bije
Urashobora kubaza ibibazo byiza byo gushyira mubikorwa mbere yo gukoresha amafaranga cyangwa igihe.
Itsinda hamwe nakazi
Amakipe asangiye ibitekerezo akora ibicuruzwa byiza, politiki, nibyemezo byo kwiga.
Gushyira mu bikorwa Isi
Urusobe rwerekezo ruhindura pigiseli indangagaciro mubintu byingirakamaro mugutondekanya ishusho.
Ururimi rwicyitegererezo ruhindura ibimenyetso byerekana amanota akoreshwa mugutanga ibimenyetso bikurikira.
Ikarita y'urusobekerane yerekana ikarita iheruka kwitegereza ku mibare igomba gusuzumwa n'ibizaza.
Ingaruka & Kurinda
Amakipe atandukanye arashobora gukoresha ijambo rimwe muburyo butandukanye, sobanura intera hakiri kare.
Ibipimo birashobora kugaragara bikomeye mugihe imikorere-yisi-itaringaniye.
Kwirengagiza ubuziranenge bwamakuru na gahunda yo gusuzuma akenshi bitanga ibisubizo byoroshye.
Igishushanyo mbonera
Tangira nururimi rusobanutse rwibisubizo ukeneye.
Toranya intsinzi imwe hamwe nuburyo bumwe bwo gutsindwa mbere yo kwipimisha.
Koresha umuderevu muto hamwe namakuru ahagarariye, ntabwo ari demo yashizweho.
Inyandiko aho imiyoboro ya Neural ifasha nuburyo bworoshye bworoshye.

Ibibazo bikunze kubazwa
Kuki imiyoboro yimitsi ikeneye ibikorwa byo gukora?
Imikorere idafite umurongo reka ibikorwa byegeranye byerekana umubano utari umurongo. Gushyira kumurongo gusa ibikorwa byakomeza kubyara umurongo.
Ese urusobe runini rw'imitsi ihora ari rwiza?
Oya. Imikorere iterwa n'akazi, amakuru, amahugurwa, gusuzuma, n'imbogamizi zoherejwe. Ibipimo byinshi birashobora kongera igiciro kandi ntibishobora kwemeza umusaruro wizewe.
