Networks Artificial zobuchopho

uthungelwano Artificial zobuchopho - zezo ukuba kwenziwe ngeeseli ezikhethekileyo - iiseli zemithambo-luvo. Akayomizekelo zezibalo zemithambo-luvo zebhayoloji, oko kukuthi, iiseli luvo yabantu.

Ngokuba lixesha lokuqala sithetha malunga neenethiwekhi zemithambo ngo-1943, yaye emva kokuba kusungulwe Perceptron Rosenblatt kwafika ixesha segolide, kunye nothungelwano zithandwa kakhulu. Noko ke, emva kokupapashwa Minsk ngo-1969, apho sisazinzulu ingu nokungasebenzi Perceptron, phantsi kweemeko ezithile, inzala kweli candelo bawa kabukhali. Kodwa ibali ayipheli kunye nothungelwano angengowamvelo. . Ngowe-1985, uJ Hopfield thaca izifundo zabo wabonisa ukuba kwenethiwekhi - isixhobo elikhulu kumatshini ukufunda.

It lathathwa eziphilayo magama kunye nemigaqo eziliqela. Neuron - uhlobo lweswitshi leyo lifumana lize emva koko edlulisela pulses (iimpawu). Ukuba neuron ufumana amandla enamandla ngokwaneleyo, kukholelwa ukuba isebenza kwaye edlulisela pulses eziseleyo luvo ezinxulumene nayo. Neuron efanayo elo ayivulwanga, ihlala nokuphumla, akunamsebenzi nokudlulisela ukubetha. Neuron iqulathe amacandelo ezininzi eziphambili: leesynapse adibanayo luvo omnye komnye kwaye ufumane pulses, Umzobo wesi, ezithwala umsebenzi abese luvo, leyo ifumana imiyalezo evela kwimithombo eyahlukeneyo. Xa neuron ifumana imiyalezo ngentla isinyuko ethile, ngoko nangoko ithumela uphawu ukuya neuron elilandelayo.

Umfuziselo lwezibalo yahlukile kancinci. Login imodeli yezibalo le neuron - yinto kumda wesangqa, elakhiwe ngekhaya inani elikhulu sineendidi. Ngalinye candelo - yenye pulses, apho bamkelwa neuron. Imveliso ye Umfuziselo nenombolo eyodwa. Oko kukuthi kumda wesangqa imodeli igalelo iguqulelwa ibe scalar, kamva kutshintshelwa kwamanye iiseli zemithambo-luvo.

uthungelwano zobuchopho bangaqeqeshwa ngeendlela ezimbini: kwaye ngaphandle notitshala. Inkqubo yokufunda inezi amanyathelo aliqela. Okokuqala, phezu thungelwano njengegalelo isivuseleli ngaphandle. Emva koko, ngokuhambisana nemigaqo iyahluka nabakhululekileyo Ipharamitha kwenethiwekhi, ngoko inethiwekhi iphendula kwigalelo ezintweni sele ngokwahlukileyo. Le nkqubo kufuneka iphindwe nje uthungelwano na ukusombulula le ngxaki. I algorithm ukufunda notitshala kukuba ngexesha ukuqeqesha uthungelwano sele unawo impendulo echanekileyo. Le ndlela iye yasetyenziswa ngempumelelo kwizicelo ezininzi, kodwa kusoloko alahlwe ngenxa yokuba ukuba eziphilayo abhalwa. networks zobuchopho baqeqeshwa ngaphandle utitshala kwimeko apho amagalelo ezaziwa kuphela. Ngokusekelwe kuwo, inethiwekhi ngcembe ufunda ukunika ixabiso iziphumo ezingcono.

Ukusetyenziswa kothungelwano zemithambo yinto ezahlukeneyo ngokwenene. Ngokufuthi zisetyenziswa imishini ukuqatshelwa, uqikelelo, ukudalwa ezahlukeneyo iinkqubo ingcali, isilinganiselo functionals. Umnatha onjalo ukwenza ingqalelo isandi okanye Imiqondiso ezamehlo ukuqikelela izibonisi exchange ukudala iinkqubo ekwazi self-learning, leyo, umzekelo, ukuba nokulungelelanisa intetho evela kwisicatshulwa okanye ipaki imoto. nothungelwano zobuchopho kwi West asetyenziswa ngakumbi, ngelishwa, iifem zasekhaya okwangoku ukuba kwamkelwa le ndlela.

Nangona ezilungileyo ANN izibalo eqhelekileyo kwezinye iindawo, neminatha kwenethiwekhi okhoyo - hayi isisombululo efanelekileyo. Ekubeni ziyakwazi ukufunda, inokuba abachananga. Ukongeza, awukwazi ngqo ukuqinisekisa ukuba inethiwekhi kuphuhliswa uvaleke kangangoko. Umphuhlisi kufuneka siqonde uhlobo ingxaki ziyafezekiswa, abe ulwazi oluninzi echaza ingxaki, ukufumana iinkcukacha yokuhlola womnatha noqeqesho, ukukhetha indlela elungileyo loqeqesho, transfer umsebenzi kunye nemisebenzi lweliso lerhamba.
