Kev kawm tob yog lub tshuab kev kawm txheej txheem uas qhia computers rau ua dab tsi los naturally rau tib neeg: kawm ua piv txwv. Kev kawm tob yog ib qho keytechnology tom qab tsav tsheb tsis muaj tsheb, ua rau lawv paub txog astop kos npe, lossis kom paub qhov txawv ntawm tus neeg taug kev los ntawm alamppost.
Ntxiv rau qhov no, kev kawm tob tuaj yeem siv rau dab tsi?
Kev kawm tob architectures xws li deepneural networks , tob kev ntseeg network, rov tshwm sim neural networks thiab convolutional neural networks ua tau siv rau cov teb suav nrog kev pom hauv computer, kev paub txog kev hais lus, kev ua haujlwm yam lus, kev paub suab, kev lim dej hauv social network, tshuab txhais lus, Qhov thib ob, qhov twg txhais tau tias kev kawm tob? Kev kawm tob yog ib tug subset ntawm lub tshuab kev kawm nyob rau hauv kev txawj ntse txawj ntse (AI) uas muaj networkscapable ntawm kev kawm unsupervised los ntawm cov ntaub ntawv uas yog tsis tsim los yog unlabeled. Kuj hu ua tob neural kev kawm los yog tob neural network.
Yog li ntawd, kev kawm tob yog dab tsi thiab nws ua haujlwm li cas?
Kev kawm tob yog a tshuab kev kawm txoj kev. Nws tso cai rau peb los cob qhia AI los kwv yees cov txiaj ntsig, muab cov txheej txheem nkag. Ob tus saib xyuas thiab tsis saib xyuas kev kawm tuaj yeem siv los cob qhia AI. Peb yuav kawm li cas kev kawm tob ua haujlwm los ntawm kev tsim ib lub dav hlau hypothetical daim pib nqi estimationservice.
Dab tsi yog kev kawm tob thiab nws cov ntawv thov?
Raws li kev kawm tob tau ua qhov kev nce qib tseem ceeb thiab kev ua tau zoo heev hauv ntau yam daim ntawv thov , tus dav siv domains ntawm kev kawm tob yog kev lag luam, kev tshawb fawb thiab tsoomfwv uas txuas ntxiv nrog rau kev sim hloov pauv, kev faib cov duab lom neeg, lub computer tsis pom kev, kuaj mob qog noj ntshav, kev ua cov lus ntuj,
Pom zoo:
Dab tsi yog qhov tseeb hauv kev kawm tob?
Hauv kev kawm tshuab, lo lus 'groundtruth' yog hais txog qhov tseeb ntawm qhov kev cob qhia cov txheej txheem rau kev saib xyuas kev kawm. Lub sij hawm 'ground truthing' yog hais txog cov txheej txheem ntawm kev sau cov ntaub ntawv lub hom phiaj (provable) rau qhov kev xeem no. Muab piv nrog goldstandard
Nws puas yooj yim rau kev kawm tob?
Kev kawm tob yog muaj zog raws nraim vim nws ua rau tej yam nyuaj yooj yim. Yog vim li cas qhov kev kawm tob ua kom muaj qhov txaws yog qhov tseeb uas nws tso cai rau peb los hais ntau yam teeb meem kev kawm yav dhau los ua tsis tau raws li qhov kev poob qis qis los ntawm qhov gradient qhovntsej thiaj tsis mob, ib qho yooj yim tshaj plaws
Kev kawm tob tob yog dab tsi?
Kev kawm tob yog cov txheej txheem kev kawm tshuab uas kawm cov yam ntxwv thiab cov haujlwm ncaj qha los ntawm cov ntaub ntawv. Cov ntaub ntawv no tuaj yeem suav nrog cov duab, ntawv nyeem, lossis suab. Cov vis dis aus siv cov teeb meem kev paub txog cov duab piv txwv los piav qhia seb qhov kev kawm tob npaum li cas kawm los faib cov duab nkag mus rau hauv pawg tsim nyog
Kev kawm tob hauv kev kho mob yog dab tsi?
Deep Learning Applications in Healthcare Deep learning techniques siv cov ntaub ntawv khaws cia hauv EHR cov ntaub ntawv los daws ntau qhov kev txhawj xeeb txog kev noj qab haus huv xws li txo tus nqi ntawm kev kuaj mob tsis raug thiab kwv yees qhov tshwm sim ntawm cov txheej txheem
Puas yog kev kawm tob tob?
Kev kawm tob yog ib qho yooj yim yog tias koj xav tau ib yam dab tsi los ua haujlwm. Kev kawm tob yog qhov nyuaj heev yog tias koj xav kom nws ua haujlwm zoo. Nov yog qee qhov kev sib tw qhib hauv kev kawm tob
