Cov lej tau loj-normalized thiab nruab nrab hauv ib daim duab tas li. Nws yog ib zoo database rau cov neeg uas xav sim cov txuj ci kev kawm thiab cov qauv kev paub txog cov ntaub ntawv hauv ntiaj teb tiag tiag thaum siv kev siv zog tsawg kawg nkaus rau kev ua ntej thiab formatting.
Tsuas yog li ntawd, Mnist cov ntaub ntawv yog dab tsi?
MNIST (Mixed National Institute of Standards and Technology) database yog dataset rau tus lej sau tes, faib los ntawm Yann Lecun's THE MNIST DATABASE ntawm tes sau tus lej lub vev xaib. Cov dataset muaj khub, "tus lej sau tus lej" thiab "label". Tus lej nyob ntawm 0 txog 9, txhais tau tias 10 tus qauv hauv tag nrho.
Tsis tas li, muaj pes tsawg tus yam ntxwv muaj rau peb rau kev kwv yees hauv Mnist tus lej dataset? Cov MNIST cov ntaub ntawv muaj 60, 000 qhov kev cob qhia thiab 10, 000 qhov kev xeem ntawm cov ntawv sau tus lej (0-9) ib. Txhua tus lej yog normalized thiab nyob rau hauv ib tug grey-scale (0 - 255) duab nrog loj 28 × 28. Txhua daim duab muaj 784 pixels uas sawv cev rau nta ntawm tus lej.
Tom qab ntawd, lo lus nug yog, Mnist sawv rau dab tsi?

Mnist TensorFlow yog dab tsi?
Chaw thau khoom MNIST dataset Tus lej siv cov peev txheej tsim los ntawm TensorFlow txhawm rau rub tawm cov ntaub ntawv hauv zos thiab thauj mus rau hauv python sib txawv. Raws li qhov tshwm sim (yog tias tsis tau teev tseg), cov ntaub ntawv yuav raug rub mus rau hauv MNIST_data/ nplaub tshev.

Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Yuav ua li cas koj muab ib tug nplaub tshev nyob rau hauv ib tug nplaub tshev ntawm ib tug iPhone?
Yuav ua li cas muab Folders hauv Folders Coj mus rhaub thiab tuav ib qho app nkag mus rau hom hloov kho. Tsim ib lub nplaub tshev tshiab los ntawm kev tso ib qho app rau saum lwm tus. Sai li ob lub apps sib koom ua ke los tsim ib daim ntawv tais ceev tseg, rub lub nplaub tshev uas twb muaj lawm hauv qhov tsim tshiab ua ntej nws tuaj yeem teeb tsa
Yuav ua li cas koj coj ib tug selfie uas tsis zoo li ib tug selfie?
Muab lub koob yees duab tso rau ntawm lub koob yees duab, ua qhov ntev ntev, thiab sawv ntsug rau qhov xwm txheej tsis tshua muaj teeb meem. Ntsuas nws ntawm ib yam dab tsi, dab tsi, nyob ze. Muab lub koob yees duab tso rau hauv av rau lwm qhov kev pom. Siv lub kaum ntse ntse kom pom deb dua li koj nyob
Puas yog qhov kis nruab nrab yog ib feem ntawm lub cev txheej vim li cas los yog vim li cas ho tsis?
Lub cev txheej hauv OSI Model yog txheej qis tshaj plaws thiab siv rau kev xa cov ntaub ntawv hauv nws daim ntawv yooj yim: ntsis-qib. Qhov nruab nrab kis tau tus mob tuaj yeem yog wired lossis wireless. Cov txheej txheem ntawm lub cev nyob rau hauv ib tug qauv wired muaj xws li cables thiab connectors uas yog siv los nqa cov ntaub ntawv los ntawm ib qho chaw mus rau lwm qhov
Yuav ua li cas koj tsim ib tug rau ntau txoj kev sib raug zoo nyob rau hauv ib tug database system?
Txhawm rau tsim kom muaj kev sib raug zoo ib leeg rau ob qho tib si ntawm thaj chaw (feem ntau yog thawj qhov tseem ceeb thiab txawv teb chaws qhov tseem ceeb) yuav tsum muaj qhov ntsuas tshwj xeeb. Txhawm rau tsim kom muaj kev sib raug zoo ib-rau-ntau Lub teb ntawm ib sab (feem ntau yog qhov tseem ceeb) ntawm kev sib raug zoo yuav tsum muaj qhov ntsuas tshwj xeeb
