Mawonekedwe ophatikizika a Photonic, kapena tchipisi cha kuwala, atha kupereka maubwino ambiri kuposa anzawo amagetsi, monga kuchepetsa kugwiritsa ntchito mphamvu komanso kuchepa kwa latency pakuwerengera. Ichi ndichifukwa chake ofufuza ambiri amakhulupirira kuti amatha kukhala othandiza kwambiri pakuphunzira makina ndi ntchito zanzeru zopanga (AI). Intel amawonanso chiyembekezo chachikulu chogwiritsa ntchito ma silicon photonics mbali iyi. Gulu lake lofufuza mu mwatsatanetsatane njira zatsopano zomwe zingabweretse ma neural network optical sitepe pafupi ndi zenizeni.
Posachedwapa , yoperekedwa ku kuphunzira kwa makina, ikufotokoza momwe kafukufuku wokhudzana ndi optical neural network adayambira. Kafukufuku wa David AB Miller ndi Michael Reck wasonyeza kuti mtundu wa photonic circuit wotchedwa Mach-Zehnder interferometer (MZI) ukhoza kukhazikitsidwa kuti upangitse 2 Γ 2 matrix kuchulukitsa pamene aikidwa MZI pa mauna atatu atatu kuti achulukitse matrices akuluakulu, munthu angathe. pezani dera lomwe limagwiritsa ntchito matrix-vector multiplication algorithm, mawerengedwe oyambira omwe amagwiritsidwa ntchito pophunzira makina.
Kafukufuku watsopano wa Intel adayang'ana kwambiri zomwe zimachitika pamene zolakwika zosiyanasiyana zomwe tchipisi tating'onoting'ono timatha kukhala nazo panthawi yopanga (popeza ma computational photonics ndi analogi m'chilengedwe) zimayambitsa kusiyana pakulondola kwamawerengedwe pakati pa tchipisi tosiyanasiyana tamtundu womwewo. Ngakhale kuti maphunziro ofanana adachitidwa, m'mbuyomu adayang'ana kwambiri kukhathamiritsa pambuyo pakupanga kuti athetse zolakwika zomwe zingatheke. Koma njira iyi imakhala yosasinthika chifukwa ma netiweki amakulirakulira, zomwe zimapangitsa kuti pakhale mphamvu yamakompyuta yofunikira kukhazikitsa ma network owoneka bwino. M'malo mokhathamiritsa pambuyo pakupanga, Intel adaganizira zophunzitsira kamodzi asanapange pogwiritsa ntchito zomangamanga zolekerera phokoso. Reference optical neural network idaphunzitsidwa kamodzi, pambuyo pake magawo a maphunzirowo adagawidwa pamisonkhano ingapo yopangidwa ndi mitundu yosiyanasiyana yazigawo zawo.
Gulu la Intel lidaganizira zomanga ziwiri zomangira zida zanzeru zopangira zida zochokera ku MZI: GridNet ndi FFTNet. GridNet imayika MZIs mu gridi, pomwe FFTNet imayika agulugufe. Pambuyo pophunzitsa onse moyerekezera pa ntchito yolemba pamanja yozindikira mozama kuphunzira mozama (MNIST), ofufuzawo adapeza kuti GridNet idapeza zolondola kwambiri kuposa FFTNet (98% vs. 95%), koma zomangamanga za FFTNet zinali "zolimba kwambiri." M'malo mwake, magwiridwe antchito a GridNet adatsikira pansi pa 50% ndikuwonjezera phokoso lopanga (kusokoneza komwe kumatengera zolakwika zomwe zingatheke pakupanga ma chip), pomwe FFTNet idakhalabe yosasinthika.
Asayansiwa akuti kafukufuku wawo amayala maziko a njira zophunzitsira zanzeru zopanga zomwe zitha kuthetsa kufunika kokonza tchipisi tating'onoting'ono zikapangidwa, kupulumutsa nthawi ndi zinthu zofunika.
"Monga momwe zimapangidwira, zolakwika zina zitha kuchitika zomwe zikutanthauza kuti padzakhala kusiyana pang'ono pakati pa tchipisi zomwe zingakhudze kulondola kwa mawerengedwe," alemba a Casimir Wierzynski, director wamkulu wa Intel AI Product Group. "Ngati ma neural optical entries akuyenera kukhala gawo lothandizira la AI ββhardware ecosystem, adzayenera kupita ku tchipisi zazikulu ndi matekinoloje opanga mafakitale. Kafukufuku wathu akuwonetsa kuti kusankha kamangidwe koyenera kutsogolo kumatha kukulitsa mwayi woti tchipisi tating'onoting'ono tikwaniritse zomwe tikufuna, ngakhale pakakhala kusiyanasiyana kopanga."
Nthawi yomweyo Intel ikuchita kafukufuku, woyimira MIT PhD Yichen Shen adakhazikitsa bungwe loyambira ku Boston Lightelligence, lomwe lakweza $ 10,7 miliyoni pazachuma komanso chipangizo chopangira makina opangira makina ophunzirira makina chomwe chimathamanga kuwirikiza ka 100 kuposa tchipisi tamakono tamagetsi komanso chimachepetsa kugwiritsa ntchito mphamvu mwadongosolo la ukulu, chomwe chikuwonetsanso momveka bwino lonjezo laukadaulo wamafotoko.
