Intaneti yokumba ubongo

Amapanga Intaneti ubongo - ndi amene amapangidwa ndi maselo wapadera - manyuroni. Iwo ali zitsanzo masamu a manyuroni zamoyo ie, maselo amene amapanga mantha dongosolo anthu.

Kwa nthawi yoyamba tikulankhula Intaneti ubongo mu 1943, ndipo pambuyo Kutulukira Perceptron Rosenblatt anadza golide nyengo, ndi kulumikiza zatchuka kwambiri. Komabe, pambuyo buku la Minsk mu 1969, chimene wasayansi watsimikizira za inefficiency wa Perceptron, akamaziwononga, chidwi mu gawo ili anagwa zikuchepa. Koma nkhani sikuthetsa ndi Intaneti yokumba. . Mu 1985, J. Hopfield anapereka maphunziro awo natsimikizira kuti ubongo zopezera - chida chachikulu kwa makina kuphunzira.

Iwo anaitenga ku zamoyo mfundo zingapo ndipo mfundo. Minyewa - mtundu wa lophimba amene alandira kenako transmits nyemba (zizindikiro). Ngati minyewa amalandira patsogolo mokwanira amphamvu, akukhulupirira kuti adamulowetsa ndi transmits nyemba otsala manyuroni kugwirizana nazo. Minyewa yemweyo amene sanali adamulowetsa, ikhala pa mpumulo, zilibe zimafalitsa zimachitika. Minyewa tichipeza zigawo zingapo zazikulu: synapses kuti kulumikiza manyuroni wina ndi mzake ndi kulandira nyemba, axon, zomwe zimafalitsa zikhumbo ntchito ndi dendrites, amene alandira chizindikiro ku magwero osiyanasiyana. Pamene minyewa akulandira mopupuluma pamwamba pakhomo zina, nthawi yomweyo akutumiza mbendera za minyewa lotsatira.

Lachitsanzo masamu ndi zosiyana pang'ono. Malowedwe masamu chitsanzo cha ubongo ndi - ndi vekitala, amene wapangidwa ndi ambiri zigawo zikuluzikulu. Aliyense wa chigawo chimodzi - ndi imodzi mwa nyemba, amene amalandiridwa ndi minyewa ya. The linanena bungwe la chitsanzo ndi chiwerengero umodzi. Kuti, mu chitsanzo athandizira vekitala ali n'kukhala scalar ndi, anasamutsidwira manyuroni ena.

Intaneti ubongo akhoza kuphunzitsidwa njira ziwiri: ndipo popanda mphunzitsi. Kuphunzira imakhala njira zingapo. Choyamba, pa maukonde ndi athandizira ku nzothandiza kunja. Ndiye, mogwirizana ndi malangizo zosiyanasiyana magawo ufulu wa maukonde ubongo, ndiye maukonde Yankho zikuchitika athandizira kale mosiyana. ndondomeko ayenera mobwerezabwereza bola maukonde sikumaŵathetsa vuto. The aligorivimu kuphunzira ndi mphunzitsi kuti pa kuphunzitsa maukonde kale yankho lolondola. njira wakhala bwinobwino ntchito ntchito zambiri, koma kawirikawiri amawanena kuti chakuti ndi biologically akuimira. Intaneti ubongo amaphunzitsidwa popanda mphunzitsi mu choncho kumene zolowetsa kokhaku. Kuchokera pa iwo, maukonde pang'onopang'ono amaphunzira kupereka bwino phindu zotuluka.

Ntchito Intaneti ubongo kwenikweni osiyanasiyana. Nthawi zambiri ntchito automate kuzindikira, kulosera, chilengedwe zosiyanasiyana machitidwe Katswiri, chiyerekezo cha functionals. Woterowo maukonde angachichite kuzindikira phokoso kapena chizindikiro kuwala kulosera kuwombola zizindikiro kulenga machitidwe amatha kudziletsa kuphunzira, amene angathe Mwachitsanzo, lithe mawu lemba anapatsidwa kapena paki galimoto. Intaneti ubongo mu West ntchito kumufotokozera, mwatsoka, Makampani zoweta sizinathe anatengera njira imeneyi.

Ngakhale ubwino ANN pa kuwerengetsera ochiritsira m'madera ena, ndi kulumikiza anthu ogwira alipo ubongo - osati yankho abwino. Popeza angathe kuphunzira, iwo akhoza kukhala wolakwa. Komanso, inu simungakhoze basi akutsimikizira kuti anayamba ubongo maukonde ndi mulingo woyenera. mapulogalamu ayenera timvetsetsetse chikhalidwe cha vuto akulankhula, ndi zambiri amene akufotokoza vuto, kupeza deta kukayezetsa ndi maukonde maphunziro, kusankha njira yoyenera maphunziro, kutengerapo ntchito ndi ntchito adder.
