Chakagadzirwa Neural network

Chakagadzirwa Neural network - ndedziya dzine masero anokosha - Tutsinga tunofambisa mashoko utwu. Ndivo kwemasvomhu yemashoko zvoutachiona Tutsinga tunofambisa mashoko utwu, kureva, masero kuti vanoumba huta womunhu hurongwa.

Kokutanga tiri kutaura pamusoro Neural network muna 1943, uye pashure nokugadzirwa kwakaitwa Perceptron Rosenblatt rakasvika chendarama yaitonga, uye network wazova chaizvo. Zvisinei, mushure Bhuku Minsk muna 1969, umo musayendisiti hwakaratidza inefficiency pamusoro Perceptron, pasi zvimwe zvinhu, asi kufarira nemauto akawira nehasha. Asi nyaya hazvirevi kuguma chakagadzirwa network. . Muna 1985, J. Hopfield akapa zvidzidzo zvavo uye akaratidza kuti Neural Network - chombo zvikuru muchina kudzidza.

Rakanga rakumbirwa kubva zvipenyu wandei pfungwa uye nenheyo. Dzouropi - rudzi chinja iyo anogamuchira uye ipapo transmits kuti pulses (anonongedzera). Kana dzouropi anogamuchira zvakakwana simba tichimhanya, zvinofungidzirwa kuti zviri kusashanda uye transmits kuti pulses asara Tutsinga tunofambisa mashoko utwu chokuita nayo. Dzouropi chete yakanga isina kusashanda, zvazvinosarira pa zororo, risingabereki fambisa kufamba kweropa. Dzouropi chinosanganisira anoverengeka chikuru zvinoriumba: synapses kuti batanidza Tutsinga tunofambisa mashoko utwu kune mumwe uye kugamuchira pulses, axon, izvo wokushandura nomunhu basa uye dendrites, izvo anogamuchira anonongedzera hwatingawana siyana. Kana dzouropi anopiwa KUDA pamusoro imwe chikumbaridzozve, pakarepo anotuma chiratidzo unotevera dzouropi.

The kwemasvomhu womuenzaniso chinguva zvakasiyana. Login kwemasvomhu muenzaniso mumwe dzouropi - ari Vector, iro rinoumbwa vakawanda zvinoriumba. Mumwe nomumwe rokuti - mumwe pulses, ayo kuburikidza dzouropi yakagamuchirwa. The goho of womuenzaniso imwe nhamba. Uko, ari muenzaniso chiyamuro Vector ari kutendeuka kuva scalar, papera kune dzimwe Tutsinga tunofambisa mashoko utwu.

Neural network inogona vakadzidziswa nenzira mbiri: pamwe uye pasina mudzidzisi. The hwekudzidza ine matanho akawanda. Chokutanga, pane zvakarukwa ndiyo mazano kubva kunze anotikurudzira. Zvadaro, maererano nemirau siyana vakasununguka parameters ari Neural Network, ipapo pomumbure anopindura chiyamuro mikana yakawanda yokukurudzira kare zvakasiyana. The muitiro rinofanira kudzokororwa sokuvapo pomumbure hakurevi kugadzirisa dambudziko. The kudzidza algorithm nomudzidzisi ndechokuti panguva kudzidzisa nemambure anotova mhinduro yakarurama. Nzira iyi rave vakabudirira kushandiswa mafomu zhinji, asi kazhinji vakashorwa nokuda chokwadi kuti pakugadzira vanomirira. Neural network vakadzidziswa pasina mudzidzisi panyaya apo chete anozivikanwa zvinoshandisa pakurima. Kubva kwavari, pomumbure zvishoma nezvishoma anodzidza kupa zvakanakisisa ukoshi outputs.

Kushandisa Neural network zviri siyana. Vari raiwanzoshandiswa michina kuzivikanwa, kufungidzira, kusikwa siyana nyanzvi mugadziriro, rakada functionals. Yakadaro samambure anogona kuita ruzha pamutemo kana Manyiminya anonongedzera kufungidzira Exchange zviratidzi pave nehurongwa anokwanisa kuzvidzora kudzidza, izvo zvinogona Somuenzaniso, kuti synthesize kutaura kubva murugwaro yakapiwa kana motokari paki. Neural network iri West anoshandiswa maziso, zvinosuruvarisa mudzimba yemakambani havasati vakanga vava nzira iyi.

Pasinei zvakanakira ANN pamusoro kwakajairika Masvomhu mune dzimwe nzvimbo, boka raivapo Neural network - kwete yakanaka mhinduro. Sezvo ivo vanokwanisa kudzidza, vangava chakaipa. Uyezve, unogona haisiri kuchaita kuti dzakabudirira Neural Network iri Zvakanyanya Kunaka Panguva Yepamuviri. The yokuvaka anofanira kunzwisisa hunhu dambudziko riri kugadziriswa richikodzera, vane zvakawanda kuti zvinonyatsorondedzera dambudziko, vawane mashoko kunovhenekwa uye kurovedza network, kusarudza nzira yakarurama yokudzidziswa, kuchinjwa nerevane nechiva mabasa.
