Chimene muyenera kudziwa ponena za chisinthiko cha nzeru zopanga nzeru
Kuphunzira kwakukulu ndi mawonekedwe amphamvu a kuphunzira makina (ML) omwe amamanga zovuta zomangamanga zotchedwa neural networks pogwiritsira ntchito deta yambiri (zambiri).
Kuphunzira Kwakuya Tanthauzo
Kuphunzira mwakuya ndi njira yogwiritsira ntchito ML pogwiritsa ntchito zigawo zingapo zamagetsi a neural kuti agwiritse ntchito mitundu yovuta ya deta. Nthaŵi zina amatchedwa maphunziro achikulire, kuphunzira mozama kumagwiritsa ntchito mitundu yosiyanasiyana ya maukonde a neural kuphunzira zinthu (zomwe zimatchedwanso ziwonetsero) ndikuzipeza mumagulu akuluakulu a deta, yosasinthika deta (data yosasinthidwa). Chimodzi mwa zochitika zoyambirira zophunzirira kuphunzira kwakukulu chinali pulogalamu yomwe inagwira bwino zithunzi za amphaka kuchokera mu mavidiyo a YouTube.
Zitsanzo Zozama Kwambiri pa Moyo Wa Tsiku Lililonse
Kuphunzira kwakukulu sikugwiritsidwe kokha pakuzindikira mawonekedwe, komabe kumasuliridwa kwa chinenero, kudziwidwa kwachinyengo, ndi kusanthula deta zomwe zimasonkhanitsidwa ndi makampani okhudza makasitomala awo. Mwachitsanzo, Netflix amagwiritsa ntchito kuphunzira mwakuya kusanthula zizolowezi zanu zowonera ndikuwonetsa zomwe zikuwonetsa komanso mafilimu omwe mumafuna kuwonekerani. Ndi momwe Netflix amadziwira kuyika mafilimu amachitidwe ndi zolemba zamtundu wanu mumsewu wotsatira. Amazon ikugwiritsa ntchito kwambiri pophunzira zomwe mwagula posachedwapa komanso zinthu zomwe mwasakafuna posachedwapa kuti mupange malingaliro a albamu yatsopano ya nyimbo zomwe mukufuna kuziganizira komanso kuti muli mumsika wa masewera achikasu ndi achikasu nsapato. Monga kuphunzira kozama kumapereka chidziwitso chochuluka kuchokera ku deta yosapangidwira ndi yaiwisi, makampani angapindulitse kuyembekezera zosowa za makasitomala awo pamene inu, kasitomala mungapeze zambiri zokhudzana ndi makasitomala.
Mapulani a Neural Networks ndi Kuphunzira Kwambiri
Kuti tiphunzire mwakuya kumvetsetsa, tiyeni tiwone ngati tikuyerekezera ndi neural network (ANN). Pofuna kuphunzira mwakuya, taganizirani za nyumba yathu yaofesi ya nsanjika khumi ndi zisanu ndi imodzi yokhala ndi nyumba zina zisanu ndi zina. Pali nyumba zitatu kumbali iliyonse ya msewu. Nyumba yathu imamanga A ndipo imagawira mbali imodzi ya msewu monga nyumba B ndi C. Pansi pa msewu kumanga A ndikumanga 1, ndipo kudutsa pa B kumanga 2, ndi zina zotero. Nyumba iliyonse ili ndi malo osiyanasiyana, imapangidwa kuchokera ku zipangizo zosiyana ndipo ili ndi mitundu yosiyana yojambula kuchokera kwa ena. Komabe, nyumba iliyonse imakonzedweratu padera (maudindo) a maofesi (node) -ndipo nyumba iliyonse ndi yapadera ya ANN.
Tangoganizani kuti pulogalamu ya digito ikufika pomanga A, yomwe ili ndi mauthenga osiyanasiyana osiyanasiyana kuchokera kuzinthu zosiyanasiyana monga malemba, mavidiyo, mitsinje, ma telefoni, mafunde a ma radiyo ndi zithunzi-komabe zimafika pang'onopang'ono imodzi satchulidwa kapena kusankhidwa mwanjira iliyonse yodalirika (deta yosadziwika). Chidziwitsocho chimatumizidwa kupyola pansi ponse kuyambira 1 mpaka 15 th kuti agwiritsidwe ntchito. Pambuyo pa chidziwitsochi chikufika pa 15 pansi (kutuluka), imatumizidwa ku 1 st floor (kulowetsa) kwa nyumba 3 pamodzi ndi zotsatira zomaliza zomanga nyumba A. Kumanga 3 kumaphunzira ndikupanga zotsatira zomwe zimamangidwa ndi kumanga A ndi Kenaka amachititsa kuti chidziwitsocho chigwedezeke pamtunda uliwonse mofanana. Zomwe zafika kumtunda wapamwamba wa nyumba 3, zimatumizidwa kuchokera kumeneko ndi zotsatira za zomangamanga kuti zimangidwe 1. Kuphunzira 1 kumaphunzira kuchokera ndipo kumaphatikizapo zotsatira kuchokera kumanga 3 asanayambe kukonza pansi. Kumanga 1 kumapereka chidziwitso ndi zotsatirapo mofanana ndi kumanga C, zomwe zimachitika ndikutumiza kumanga 2, yomwe imachita ndi kutumiza kumangidwe B.
ANN iliyonse (yomanga) mu chitsanzo chathu ikufufuza chinthu china mu deta yosadziwika (chingwe cha chidziwitso) ndikupereka zotsatira ku nyumba yotsatira. Nyumba yotsatira imaphatikizapo (imaphunzira) zotsatira zake (zotsatira) kuchokera kumbuyo. Monga momwe deta ikuyendetsedwa ndi ANN (nyumba) iliyonse, imakhala yokonzedwa ndi kulembedwa (yosasulidwa) ndi mbali inayake kuti pokhapokha ngati deta ifika pamapeto otsiriza (chipinda chapamwamba) cha ANN (yomanga) yomaliza, imaikidwa ndi kulembedwa (yowonjezereka kwambiri).
Artificial Intelligence, Kuphunzira Machine, ndi Kuphunzira Kwambiri
Kodi kuphunzira kwakukulu kumaphatikizapo bwanji chithunzi chonse cha nzeru zamakono (AI) ndi ML? Kuphunzira mozama kumawonjezera mphamvu ya ML ndikuwonjezera ntchito zosiyanasiyana AI angathe kuchita. Chifukwa kuphunzira kwakukulu kumadalira kugwiritsa ntchito maukonde a neural ndi kuzindikira zomwe zili muzinthu zosungiramo deta m'malo mwa zosavuta zenizeni za ntchito , zimatha kupeza ndi kugwiritsira ntchito mfundo zosawerengeka (zosaphika) popanda kuika pulogalamuyo kuti ikhale yoyamba-nthawi -kutumizira ntchito yomwe ingayambitse zolakwika. Kuphunzira mozama kumathandiza makompyuta kukhala bwino ndi bwino kugwiritsa ntchito deta kuti athandize makampani awiri ndi anthu pawokha.
