A tensor yog vector lossis matrix ntawm n-dimensions uas sawv cev rau txhua hom ntaub ntawv. Tag nrho cov nqi hauv a tensor tuav cov ntaub ntawv zoo ib yam nrog tus paub (lossis qee qhov paub) puab . Cov puab ntawm cov ntaub ntawv yog qhov dimensionality ntawm lub matrix los yog array. A tensor tuaj yeem tsim los ntawm cov ntaub ntawv nkag lossis cov txiaj ntsig ntawm kev suav.
Hauv qhov no, duab tensor yog dab tsi?
A tensor yog cov ntaub ntawv qauv. Raws li rau duab processing, cov tensor tuaj yeem siv zoo li matrix los ua cov haujlwm ntawm cov ntsiab lus, tswj cov duab . Nws kuj tseem siv tau rau kev twv ua ntej. Tensor siv ntws tensors hloov vectors los ua haujlwm.
Qhov thib ob, dab tsi yog tensor Python? Tags: numpy, Python , Tensor . A tensor yog ib lub thawv uas muaj peev xwm tsev cov ntaub ntawv nyob rau hauv N qhov ntev, nrog rau nws cov kab khiav hauj lwm, txawm hais tias muaj nuance nyob rau hauv dab tsi tensors technically yog thiab peb xa mus li cas tensors hauv kev xyaum.
Ua li no, koj yuav hloov lub tensor zoo li cas?
Yog koj xav tau hloov tus puab ntawm qhov sib txawv, koj tuaj yeem ua cov hauv qab no (piv txwv li rau 32-ntsis ntab taw tes tensor ): var = tf. Variable(tf. placeholder(tf.
Lawv yog:
- rov zoo li qub.
- nyem (tawm qhov ntev ntawm qhov loj 1 los ntawm cov duab tensor)
- expand_dims (ntxiv qhov ntev ntawm qhov loj 1)
Dab tsi yog tensor piv txwv?
A tensor field muaj a tensor sib raug rau txhua qhov chaw. Ib piv txwv yog qhov kev ntxhov siab ntawm cov khoom siv, xws li kev tsim kho kab hauv tus choj. Lwm yam piv txwv ntawm tensors suav nrog lub zog tensor , conductivity tensor , thiab inertia tensor.
