MIT tau tsim cov qauv tsim ntawm photonic processor tshiab. Nws yuav ua kom cov kev ua tau zoo ntawm optical neural networks ib txhiab zaus piv rau cov khoom siv zoo sib xws.
Lub nti yuav txo cov hluav taws xob siv los ntawm cov ntaub ntawv chaw. Peb mam li qhia koj seb nws ua haujlwm li cas.

Vim li cas peb thiaj xav tau ib lub tsev tshiab?
Optical neural networks sai dua li cov kev daws teeb meem uas siv cov khoom siv hluav taws xob. Teeb Kev sib cais ntawm cov teeb liab txoj hauv kev, thiab cov kwj laser tuaj yeem dhau los ntawm ib leeg yam tsis muaj kev cuam tshuam. Nyob rau hauv txoj kev no, txhua txoj kev taw qhia tuaj yeem ua haujlwm ib txhij, tso cai rau cov ntaub ntawv hloov pauv siab.
Tab sis muaj ib qho teeb meem - qhov loj dua lub neural network, ntau lub zog nws siv. Txhawm rau daws qhov teeb meem no, tshwj xeeb accelerator chips (AI accelerators) tau tsim los ua kom zoo dua cov ntaub ntawv hloov pauv. Txawm li cas los xij, lawv tsis ntsuas raws li peb xav tau.
Qhov teeb meem ntawm lub zog efficiency thiab scaling ntawm optical chips tau daws ntawm MIT thiab ib tug tshiab photonic accelerator architecture uas txo cov cuab yeej lub zog noj los ntawm ib txhiab lub sij hawm thiab ua hauj lwm nrog kaum lab ntawm cov neurons. Cov neeg tsim khoom hais tias yav tom ntej thev naus laus zis yuav pom daim ntawv thov hauv cov chaw khaws ntaub ntawv uas cuam tshuam nrog cov tshuab ntse ntse thiab tshuab kev kawm algorithms, thiab tseem tshuaj xyuas cov ntaub ntawv loj.
Nws zoo li cas?
Lub nti tshiab yog tsim los ntawm lub hauv paus ntawm optoelectronic circuit. Cov ntaub ntawv kis tau tseem yog encoded nrog cov teeb liab kho qhov muag, tab sis kev txheeb xyuas homodyne sib npaug yog siv rau matrix multiplication (). Qhov no yog cov txheej txheem uas tso cai rau koj los tsim cov teeb liab hluav taws xob raws li ob qho kev kho qhov muag.
Ib txoj kev taw qhia ib leeg yog siv los xa lub teeb pulses nrog cov ntaub ntawv hais txog kev tawm tswv yim thiab tawm cov neurons. Cov ntaub ntawv ntawm qhov hnyav ntawm neurons, ntawm qhov tsis sib xws, los ntawm kev sib cais. Tag nrho cov ntawm lawv "diverge" rau cov nodes ntawm ib daim phiaj ntawm homodyne photodetectors, uas xam tus nqi tso zis rau txhua neuron (txiav txim siab theem teeb liab). Cov ntaub ntawv no raug xa mus rau lub modulator, uas hloov cov teeb liab hluav taws xob rov qab mus rau optical. Tom ntej no, nws raug xa mus rau txheej tom ntej ntawm neural network thiab cov txheej txheem rov ua dua.
Hauv lawv txoj haujlwm tshawb fawb, engineers los ntawm MIT daim duab hauv qab no rau ib txheej:
Daim duab: / CC los ntawm
Tus tshiab AI accelerator architecture yuav tsum tsuas yog ib qho kev tawm tswv yim thiab ib qho kev tso tawm rau txhua tus neuron. Yog li ntawd, tus naj npawb ntawm photodetectors yog sib npaug rau tus naj npawb ntawm cov neurons, tsis yog lawv qhov hnyav coefficients.
Txoj hauv kev no tso cai rau koj kom txuag tau qhov chaw ntawm lub nti, nce tus naj npawb ntawm cov teeb liab txoj kev muaj txiaj ntsig thiab txhim kho kev siv hluav taws xob zoo. Tam sim no cov engineers los ntawm MIT tab tom tsim ib qho qauv uas yuav sim lub peev xwm ntawm cov qauv tshiab hauv kev xyaum.
Leej twg yog leej twg tab tom tsim photonic chips?
Kev loj hlob ntawm cov tshuab zoo sib xws Lightelligence yog qhov pib me me raws li hauv Boston. Cov neeg ua haujlwm hauv tuam txhab hais tias lawv AI accelerator yuav tso cai rau kev daws teeb meem kev kawm tshuab ntau pua zaus sai dua li cov khoom siv qub. Xyoo tas los, pab pawg tau ua tiav qhov kev tsim cov qauv ntawm lawv cov cuab yeej thiab npaj ua cov kev xeem.
Ua haujlwm hauv thaj chaw ntawm photonic chips thiab Cisco. Thaum pib ntawm lub xyoo lub tuam txhab tshaj tawm pib Luxtera, uas tsim photonic chips rau cov chaw zov me nyuam. Hauv particular, lub tuam txhab tsim kho vajtse interfaces uas tso cai rau koj mus cuag fiber optics ncaj qha mus rau servers. Txoj kev no ua rau kom muaj peev xwm hauv lub network thiab ua kom cov ntaub ntawv xa mus sai. Luxtera li siv cov lasers tshwj xeeb los encode cov ntaub ntawv thiab germanium photodetectors los decrypt nws.

Lwm lub tuam txhab IT loj, xws li Intel, kuj tau koom nrog cov thev naus laus zis kho qhov muag. Rov qab rau xyoo 2016, lawv tau pib tsim lawv tus kheej cov khoom siv kho qhov muag uas txhim kho cov ntaub ntawv hloov pauv ntawm cov chaw zov me nyuam. Tsis ntev los no, cov neeg sawv cev ntawm lub koom haum tias lawv npaj yuav siv cov thev naus laus zis no sab nraum cov chaw khaws ntaub ntawv - hauv lidars rau tsheb tsav tus kheej.
Dab tsi kawg
Txog tam sim no, photonic technologies tsis tuaj yeem hu ua kev daws teeb meem thoob ntiaj teb. Lawv qhov kev siv yuav tsum tau siv nyiaj ntau rau cov khoom siv rov ua dua tshiab ntawm cov chaw khaws ntaub ntawv. Tab sis kev txhim kho zoo li cov uas tau tsim los ntawm MIT thiab lwm lub koom haum yuav ua rau cov khoom siv kho qhov muag pheej yig dua thiab feem ntau yuav tso cai rau lawv mus rau hauv kev lag luam loj rau cov khoom siv hauv cov ntaub ntawv.
Peb nyob hauv Peb pab cov tuam txhab tsim IT infrastructure thiab muab kev pabcuam huab cua ntiag tug thiab hybrid. Nov yog qhov peb sau txog ntawm peb cov tuam txhab blog:
