MIT yakagadzira dhizaini nyowani yephotonic processor. Ichawedzera kushanda kwe optical neural network kane chiuru zvichienzaniswa nemidziyo yakafanana.
Iyo chip ichaderedza huwandu hwemagetsi anopedzwa nedata data. Tichakuudza kuti zvinoshanda sei.

Sei tichida chivakwa chitsva?
Optical neural network inokurumidza kupfuura zvigadziriso zvechinyakare zvinoshandisa zvinhu zvemagetsi. Chiedza kuparadzaniswa kwenzira dzechiratidzo, uye nzizi dzelaser dzinokwanisa kupfuura nepakati peumwe pasina pesvedzero. Nenzira iyi, nzira dzese dzekusaina dzinogona kushanda panguva imwe chete, zvichibvumira mazinga ekutamisa data.
Asi pane dambudziko - iyo yakakura iyo neural network, iyo yakawanda simba inopedza. Kugadzirisa dambudziko iri, accelerator machipisi (AI accelerators) ari kugadzirwa anonatsiridza kuendesa data. Nekudaro, ivo havakwire sezvatinoda.
Dambudziko rekushanda kwesimba uye kuyera kwe optical chips rakagadziriswa kuMIT uye itsva photonic accelerator architecture iyo inoderedza kushandiswa kwesimba kwechigadzirwa kane chiuru uye inoshanda nemakumi emamiriyoni eeuroni. Vagadziri vacho vanoti mune ramangwana tekinoroji ichawana application munzvimbo dzedata dzinodyidzana neakaomarara akangwara masisitimu uye muchina kudzidza algorithms, uye zvakare kuongorora data hombe.
Anomiririra chii
Iyo chip nyowani inovakwa pahwaro hweiyo optoelectronic circuit. Iyo data yakafambiswa ichiri encoded ne optical signals, asi yakaenzana homodyne yekuona inoshandiswa pakuwedzera matrix () Iyi inyanzvi inokubvumira kuti ugadzire chiratidzo chemagetsi chinobva pane maviri optical.
Nzira imwe chete yekusaina inoshandiswa kufambisa mapurusi emwenje neruzivo rwezvekupinza uye kubuda neuron. Dhata pamusoro pezviyero zveeuroni, pane zvinopesana, zvinouya kuburikidza nematanho akasiyana. Ese "anosiyana" kune nodes yegridi yehomodyne photodetectors, iyo inoverenga kukosha kwekubuda kweiyo neuron yega yega (sarudza chiyero chechiratidzo). Ruzivo urwu rwunobva rwatumirwa kune modulator, iyo inoshandura chiratidzo chemagetsi kudzoka kune optical. Tevere, inotumirwa kune inotevera layer yeneural network uye maitiro anodzokororwa.
Mubasa ravo resainzi, mainjiniya kubva kuMIT dhayagiramu inotevera yeimwe layer:

Iyo itsva AI accelerator architecture inoda chete yekupinza uye imwe yekubuda chiteshi kune yega neuron. Somugumisiro, nhamba ye photodetectors inofananidzwa nenhamba ye neuroni, panzvimbo yehuremu hwavo hwehuremu.
Iyi nzira inobvumidza iwe kuchengetedza nzvimbo pane chip, kuwedzera huwandu hweanobatsira masaini nzira uye optimize mashandisiro emagetsi. Iye zvino mainjiniya kubva kuMIT ari kugadzira prototype iyo inoedza kugona kweiyo nyowani yekuvaka mukuita.
Ndiani mumwe ari kugadzira photonic chips?
Kubudirira kwehunyanzvi hwakafanana Lightelligence idiki yekutanga yakavakirwa muBoston. Vashandi vekambani vanoti AI yavo yekumhanyisa inobvumidza kugadzirisa matambudziko ekudzidza muchina mazana enguva nekukurumidza kupfuura zvishandiso zvekare. Gore rapfuura, timu yanga ichipedzisa kugadzira prototype yemudziyo wavo uye kugadzirira kuita bvunzo.
Inoshanda mumunda we photonic chips uye Cisco. Mukutanga kwegore kambani yakazivisa kutanga Luxtera, iyo inogadzira photonic machipi enzvimbo dzedata. Kunyanya, kambani inogadzira hardware interfaces inokubvumira kuti ubatanidze fiber optics zvakananga kumaseva. Iyi nzira inowedzera network network uye inomhanyisa kuendesa data. Luxtera zvishandiso zvinoshandisa akakosha lasers encode ruzivo uye germanium photodetectors kuti inyore.

Mamwe makambani makuru eIT, akadai seIntel, anobatanidzwawo mune optical technologies. Kudzoka muna 2016, vakatanga kugadzira yavo yemeso machipisi anokwenenzvera kuendesa data pakati penzvimbo dzedata. Munguva pfupi yapfuura, vamiririri vesangano kuti vanoronga kushandisa matekinoroji aya kunze kwenzvimbo dzedata - mumalidar emotokari dzinozvityaira.
Chii chiri mutsetse wepasi
Kusvika ikozvino, photonic technologies haigoni kunzi mhinduro yepasi rose. Kuita kwavo kunoda mari hombe yezvehunyanzvi re-equipment yedata centers. Asi budiriro senge idzo dziri kuvandudzwa kuMIT nemamwe masangano dzinoita kuti machipi emaziso adhure uye angangovatendera kukwidziridzwa mumusika mukuru wemidziyo yedhata.
Isu tiri Isu tinobatsira makambani kuvandudza IT masisitimu uye kupa yakavanzika uye yakasanganiswa Cloud masevhisi. Izvi ndizvo zvatinonyora pamusoro pekambani yedu blog:
