Tag nrho kuv lub neej neeg laus, kuv tau haus dej haus cawv (tsis yog, tam sim no peb tsis tau tham txog haus dej haus nrog cov khoom tsis zoo).
Kuv yeej tsis tau txaus siab tshwj xeeb hauv lub ntiaj teb ntawm cov ntaub ntawv thev naus laus zis, thiab kuv tsis tuaj yeem ua ntau qhov matrices ntawm ib daim ntawv. Thiab kuv yeej tsis xav tau qhov no, kom koj nkag siab me ntsis txog qhov tshwj xeeb ntawm kuv txoj haujlwm, kuv tuaj yeem qhia zaj dab neeg zoo. Kuv ib zaug hais kom kuv cov npoj yaig ua haujlwm hauv Excel daim ntawv nthuav qhia, ib nrab hnub ua haujlwm tau dhau mus, kuv tau nce mus rau lawv, thiab lawv tau zaum thiab sau cov ntaub ntawv ntawm lub laij lej, yog, ntawm lub tshuab xam zauv dub zoo tib yam nrog cov nyees khawm. Zoo, yam dab tsi ntawm neural networks peb tuaj yeem tham txog tom qab no? Tab sis, raws li lawv hais tias, "zoo qhov twg peb tsis," kuv cov phooj ywg buzzed kuv pob ntseg txog augmented kev muaj tiag, txog neural networks, hais txog programming lus (tsuas yog hais txog Python).
Hauv cov lus nws zoo li yooj yim heev, thiab kuv tau txiav txim siab tias vim li cas ho tsis paub qhov txuj ci zoo li no txhawm rau siv nws hauv kuv txoj haujlwm.
Hauv tsab xov xwm no, Kuv yuav hla kuv qhov kev sim ua kom paub qhov pib ntawm Python thiab qhia rau koj kuv qhov kev xav ntawm TensorFlow chav kawm dawb los ntawm Udacity.
Taw qhia
Yuav pib nrog, nws tsim nyog sau cia tias tom qab 11 xyoo hauv kev lag luam hluav taws xob, thaum koj paub thiab ua tau txhua yam thiab txawm tias me ntsis ntxiv (raws li koj lub luag haujlwm), kev kawm radically tshiab - ntawm ib sab, ua rau muaj kev txaus siab, tab sis ntawm lwm yam - hloov mus rau hauv lub cev mob "lub zog hauv kuv lub taub hau."
Kuv tseem tsis tau nkag siab tag nrho cov ntsiab lus tseem ceeb ntawm programming thiab kev kawm tshuab, yog li koj yuav tsum tsis txhob txiav txim rau kuv hnyav dhau. Kuv vam tias kuv tsab xov xwm yuav nthuav thiab muaj txiaj ntsig rau cov neeg zoo li kuv uas nyob deb ntawm kev txhim kho software.
Ua ntej tsiv mus rau qhov kev saib xyuas hauv chav kawm, kuv yuav hais tias txhawm rau kawm nws koj yuav xav tau tsawg kawg kev paub txog Python. Koj tuaj yeem nyeem ob peb phau ntawv rau dummies (Kuv kuj tau pib kawm ntawm Stepic, tab sis tseem tsis tau paub nws tag nrho).
Cov chav kawm TensorFlow nws tus kheej yuav tsis muaj cov txheej txheem nyuaj, tab sis nws yuav tsum nkag siab tias vim li cas cov tsev qiv ntawv raug xa tuaj, yuav txhais li cas, thiab vim li cas qee yam hloov pauv rau hauv nws.
Vim li cas TensorFlow thiab Udacity?
Lub hom phiaj tseem ceeb ntawm kuv txoj kev kawm yog lub siab xav paub txog cov duab ntawm cov khoom siv hluav taws xob uas siv cov neural networks.
Kuv xaiv TensorFlow vim kuv hnov txog nws los ntawm kuv cov phooj ywg. Thiab raws li kuv nkag siab nws, chav kawm no nrov heev.
Kuv sim pib kawm los ntawm official .
Thiab tom qab ntawd kuv tau khiav mus rau ob qhov teeb meem.
- Muaj ntau cov ntaub ntawv kawm, thiab lawv tuaj nyob rau hauv ntau yam sib txawv. Nws yog qhov nyuaj heev rau kuv los tsim tsawg kawg ib daim duab ntau dua lossis tsawg dua ntawm kev daws teeb meem kev paub txog duab.
- Feem ntau ntawm cov ntawv kuv xav tau tsis tau muab txhais ua lus Lavxias. Nws tsuas yog tshwm sim uas kuv tau kawm German thaum tseem yog menyuam yaus thiab tam sim no, zoo li ntau tus menyuam yaus Soviet, kuv tsis paub lus German lossis lus Askiv. Tau kawg, thoob plaws hauv kuv lub neej neeg laus, kuv tau sim ua lus Askiv, tab sis nws hloov tawm ib yam dab tsi zoo li hauv daim duab.
Tom qab khawb ib ncig ntawm lub vev xaib official, kuv pom cov lus pom zoo mus dhau .
Raws li kuv nkag siab nws, chav kawm ntawm Coursera tau them, thiab chav kawm nws muaj peev xwm dhau "dawb dawb, uas yog, tsis muaj dab tsi."
Cov ntsiab lus ntawm chav kawm
Hoob no muaj 9 zaj lus qhia.
Thawj ntu yog cov lus qhia, uas lawv yuav qhia koj tias vim li cas nws thiaj li xav tau hauv txoj cai.
Zaj Lus Qhia #2 tau muab los ua kuv nyiam. Nws yog qhov yooj yim txaus kom nkag siab thiab tseem ua tau pom qhov kev xav ntawm kev tshawb fawb. Nyob rau hauv luv luv, nyob rau hauv zaj lus qhia no, ntxiv rau cov ntaub ntawv tseem ceeb ntawm neural tes hauj lwm, cov creators qhia yuav ua li cas siv ib leeg-txheej neural network los daws qhov teeb meem ntawm converting kub ntawm Fahrenheit mus rau Celsius.
Qhov no yog ib qho piv txwv meej heev. Kuv tseem zaum ntawm no xav txog yuav ua li cas los nrog thiab daws qhov teeb meem zoo sib xws, tab sis tsuas yog rau cov kws hluav taws xob xwb.
Hmoov tsis zoo, kuv tau txiav txim siab ntxiv, vim tias kev kawm paub tsis meej hauv cov lus tsis paub yog qhov nyuaj heev. Dab tsi cawm kuv yog qhov kuv pom ntawm Habre .
Kev txhais lus tau ua tiav zoo, cov phau ntawv Colab kuj tau txhais, yog li kuv mam li saib ob qho tib si thawj thiab cov txhais lus.
Zaj Lus Qhia No. 3 yog, qhov tseeb, kev hloov kho ntawm cov ntaub ntawv los ntawm kev qhia TensorFlow. Hauv qhov kev qhia no, peb siv ntau txheej neural network los kawm paub faib cov duab ntawm cov khaub ncaws (Fashion MNIST dataset).
Zaj Lus Qhia No.4 txog No.7 kuj yog ib qho kev hloov kho ntawm qhov kev qhia. Tab sis vim yog qhov tseeb tias lawv tau raug teeb tsa kom raug, tsis tas yuav nkag siab qhov kev kawm ntawm koj tus kheej. Hauv cov tshooj lus no peb yuav qhia luv luv txog cov kev sib txuas ntawm cov neural ultra-precise, yuav ua li cas thiaj li ua tau qhov tseeb ntawm kev cob qhia thiab txuag tus qauv. Nyob rau tib lub sijhawm, peb yuav daws qhov teeb meem ntawm kev faib cov miv thiab dev hauv daim duab.
Zaj Lus Qhia No.8 yog ib chav kawm uas nyias muaj nyias, muaj ib tug xib hwb txawv, thiab chav kawm nws tus kheej kuj dav heev. Zaj lus qhia yog hais txog lub sij hawm series. Txij li thaum kuv tsis txaus siab rau nws tseem, kuv luam nws diagonally.
Qhov no xaus nrog zaj lus qhia #9, uas yog kev caw mus kawm dawb ntawm TensorFlow lite.
Qhov koj nyiam thiab tsis nyiam
Kuv mam li pib nrog cov pros:
- Chav kawm yog dawb
- Cov chav kawm yog nyob rau TensorFlow 2. Qee phau ntawv uas kuv pom thiab qee qhov kev kawm hauv Is Taws Nem tau nyob ntawm TensorFlow 1. Kuv tsis paub tias muaj qhov sib txawv loj, tab sis nws yog qhov zoo los kawm cov ntawv tam sim no.
- Cov kws qhia ntawv hauv daim vis dis aus tsis yog kev ntxhov siab (txawm hais tias nyob rau hauv Lavxias teb sab version lawv tsis nyeem zoo siab ib yam li hauv thawj)
- Chav kawm tsis siv sijhawm ntau
- Hoob no tsis ua rau koj tu siab lossis tsis muaj kev cia siab. Cov dej num hauv chav kawm yog qhov yooj yim thiab yeej ib txwm muaj lus qhia hauv daim ntawv ntawm Colab nrog cov kev daws teeb meem yog tias qee yam tsis meej (thiab ib nrab ntawm cov haujlwm tsis meej rau kuv)
- Tsis tas yuav tsum tau nruab ib yam dab tsi, tag nrho cov kev sim ua haujlwm ntawm chav kawm tuaj yeem ua tiav hauv qhov browser
Tam sim no cov cons:
- Yeej tsis muaj cov khoom siv tswj. Tsis muaj kev xeem, tsis muaj haujlwm, tsis muaj dab tsi los kuaj xyuas qhov kev paub ntawm chav kawm
- Tsis yog tag nrho kuv cov notepads ua haujlwm raws li lawv yuav tsum tau ua. Kuv xav tias hauv zaj lus qhia thib peb ntawm thawj chav kawm hauv Askiv Colab tau cuam tshuam qhov yuam kev thiab kuv tsis paub yuav ua li cas nrog nws
- Yooj yim saib tsuas yog hauv computer. Tej zaum kuv tsis nkag siab tag nrho, tab sis kuv nrhiav tsis tau Udacity app ntawm kuv lub smartphone. Thiab lub xov tooj ntawm tes ntawm lub xaib tsis teb, uas yog, yuav luag tag nrho thaj chaw tshuaj ntsuam yog nyob los ntawm cov ntawv qhia zaub mov, tab sis kom pom cov ntsiab lus tseem ceeb koj yuav tsum tau mus rau sab xis dhau ntawm thaj chaw saib. Tsis tas li ntawd, cov yeeb yaj kiab tsis tuaj yeem saib hauv xov tooj. Koj tsis tuaj yeem pom dab tsi ntawm qhov screen ntsuas tsuas yog 6 ntiv tes.
- Qee yam hauv chav kawm yog chewed ntau zaus, tab sis tib lub sijhawm, cov khoom tsim nyog tiag tiag ntawm cov tes hauj lwm convolutional lawv tus kheej tsis chewed hauv chav kawm. Kuv tseem tsis tau nkag siab tag nrho lub hom phiaj ntawm qee qhov kev tawm dag zog (piv txwv li, Max Pooling yog dab tsi).
Txoj kev xaus
Muaj tseeb koj twb twv tias qhov txuj ci tseem ceeb tsis tshwm sim. Thiab tom qab ua tiav qhov kev kawm luv luv no, nws tsis tuaj yeem nkag siab tiag tiag li cas neural networks ua haujlwm.
Tau kawg, tom qab qhov no kuv tsis tuaj yeem daws kuv qhov teeb meem ntawm kuv tus kheej nrog kev faib cov duab ntawm cov keyboards thiab cov nyees khawm hauv switchgears.
Tab sis tag nrho cov chav kawm yog pab tau. Nws qhia tau hais tias yam twg tuaj yeem ua tiav nrog TensorFlow thiab cov kev taw qhia twg yuav coj mus ntxiv.
Kuv xav tias thawj zaug kuv yuav tsum kawm cov hauv paus ntawm Python thiab nyeem cov ntawv hauv Lavxias hais txog yuav ua li cas neural networks ua haujlwm, thiab tom qab ntawd coj mus rau TensorFlow.
Thaum kawg, kuv xav hais ua tsaug rau kuv cov phooj ywg uas tau thawb kuv los sau thawj tsab xov xwm ntawm Habr thiab pab kuv format nws.
PS Kuv yuav zoo siab tau pom koj cov lus thiab txhua qhov kev thuam.
