Ngaphandle kokucaphuna ngokuqondile embhalweni unginikeze isifinyezo sokuthi uyini umshini weBoltzmann onqunyelwe?
Context:Umshini we-Boltzmann onqunyelwe (i-RBM) iyinethiwekhi ye-neural yokudala ekwazi ukufunda ukusatshalaliswa okungenzeka kokungeniswa kwayo.  Ama-RBM ekuqaleni asungulwa ngaphansi kwegama elithi Harmonium nguPaul Smolensky ngo-1986, futhi aduma kakhulu ngemuva kokuthi uGeoffrey Hinton kanye nabasebenzisana nabo basungule ama-algorithms okufunda ngokushesha ngabo maphakathi no-2000. Ama-RBM athole ukusetshenziswa ekunciphiseni ubukhulu, ukuhlukaniswa, ukuhlunga ngokubambisana, ukufunda isici, ukumodeliswa kwesihloko ngisho nemishini eminingi ye-quantum yomzimba. Bangase baqeqeshwe ngezindlela eziqondiswayo noma ezingaqondiswa, kuye ngomsebenzi.  Njengoba igama lawo lisho, ama-RBM ayindlela ehlukile yemishini kaBoltzmann, enomkhawulo wokuthi ama-neurons awo kufanele enze igrafu enezigaba ezimbili: i-pair of nodes kusuka eqenjini ngalinye lamaqembu amayunithi (evame ukubizwa ngokuthi amayunithi "abonakalayo" futhi "acashile" ngokulandelana) angaba nokuxhumana okufana phakathi kwawo; futhi akukho ukuxhumana phakathi kwama-node ngaphakathi kweqembu. Ngokuphambene nalokho, imishini kaBoltzmann "engavinjelwe" ingaba nokuxhumana phakathi kwamayunithi afihliwe. Lokhu kuvimbela kuvumela ama-algorithm okuqeqesha asebenza kangcono kunalawo atholakalayo ekilasini elijwayelekile lemishini kaBoltzmann, ikakhulukazi i-algorithm yokwehluka okuphikisanayo okususelwa ku-gradient.  Imishini yeBoltzmann enqunyelwe ingasetshenziswa futhi kumanethiwekhi okufunda okujulile. Ikakhulukazi, amanethiwekhi okholo olujulile angenziwa "ngokufaka" ama-RBM futhi ngokuzithandela alungise inethiwekhi ejulile evelayo ngokuhla kwe-gradient nokusabalalisa emuva.
Umshini we-Boltzmann onqunyelwe (i-RBM) isigaba senethiwekhi ye-neural yokufakelwa eyasungulwa nguPaul Smolensky futhi yathandwa nguGeoffrey Hinton. Ama-RBM abelokhu ewusizo ekusetshenzisweni okuhlukahlukene emkhakheni wokufunda komshini futhi angaqeqeshwa ngezindlela eziqondisiwe nezingaqondisiwe.  I-RBMS iyinhlobo elinganiselwe yemishini kaBoltzmann ebopha ama-neurons ayo; ama-node amabili avela eqenjini ngalinye lama-neurons, abonakalayo nafihliwe akha igrafu enezingxenye ezimbili. Ukuxhumana kungaba kuphela phakathi kwamaqembu amabili hhayi ngaphakathi kwamaqembu (okubonakalayo nokufihliwe). Lokhu kuhlanganiswa okunomkhawulo kuholela ekutheni sikwazi ukuqeqesha ama-algorithm ngendlela ephumelela kakhudlwana.  Ama-RBM nawo angahlanganiswa namanethiwekhi okufunda ajulile njengamanethiwekhi okukholelwa okujulile anezinketho zokulungisa lawo manethiwekhi ngokusebenzisa ukwehla kwe-gradient nokusabalalisa emuva.
