Nyob rau hauv linear algebra, tus lej tus nqi decomposition ( SVD ) yog ib tug factorization ntawm ib tug tiag tiag los yog complex matrix. Nws yog qhov generalization ntawm eigendecomposition ntawm ib txwm matrix (piv txwv li, ib tug symmetric matrix nrog non-negative eigenvalues) toany matrix ntawm ib tug extension ntawm lub polardecomposition.

Ntxiv mus, kev siv SVD yog dab tsi?

Lub Singular-Value Decomposition, los yog SVD forshort, yog ib tug matrix decomposition txoj kev rau txo ib tug matrix rau nws constituent qhov chaw nyob rau hauv thiaj li yuav ua rau tej yam tom ntej matrix xam yooj yim. Rau cov ntaub ntawv ntawm simplicity peb yuav tsom mus rau SVD rau matrices tiag tiag thiab tsis quav ntsej cov ntaub ntawv forcomplex tooj.

Tsis tas li ntawd, lub ntsiab lus ntawm SVD yog dab tsi? Spontaneous Vaginal Delivery ( SVD ) yog qhov chaw mos uas tshwm sim ntawm nws tus kheej, tsis tas siv tshuaj lossis lwm yam cuab yeej los pab rub tus menyuam tawm. We have found 10 more results for SVD . Singular Value Decomposition.

SVD puas zoo ib yam li PCA?

Tus nqi decomposition ( SVD ) thiab kev tsom xam cov ntsiab lus tseem ceeb ( PCA ) yog ob eigenvaluemethods siv los txo cov ntaub ntawv siab-dimensional rau hauv tsawg dua qhov chaw thaum khaws cov ntaub ntawv tseem ceeb. Raws li PCA siv cov SVD nyob rau hauv nws cov xam, kom meej meej muaj ib co'extra' tsom xam ua.

Lub sij hawm kho mob SVD yog dab tsi?

Spontaneous vaginal delivery, ib hom yug tsis muaj kho mob kev cuam tshuam. Swine vesicular kab mob, ib tug kab mob kis rau npua. Cov kab mob me me, ib tsev neeg suav nrog Lipohyalinosis lossis Binswanger tus kab mob.
