A sparse matrix yog a matrix uas yog suav nrog feem ntau xoom qhov tseem ceeb Sparse matrices yog txawv ntawm matrices nrog feem ntau tsis yog xoom qhov tseem ceeb, uas yog hu ua matrices ntom. … Qhov piv txwv muaj 13 pes tsawg qhov tseem ceeb ntawm 18 lub ntsiab hauv matrix, muab cov matrix no qhov qhab nia ntawm 0.722 lossis txog 72%.
Yuav ua li cas yog hom sparse matrices?
Muaj xya yam muaj sparse matrix:
- csc_matrix: Compressed Sparse Kem format.
- csr_matrix: Compressed Sparse Kab hom.
- bsr_matrix: Thaiv kab kab hom.
- lil_matrix: Daim ntawv teev npe hom.
- dok_matrix: Phau ntawv txhais lus ntawm Keys format.
- coo_matrix: COOrdinate format (aka IJV, triplet format)
Yuav ua li cas koj thiaj nrhiav tau qhov sib cais matrix?
Kom xyuas seb cov matrix puas yog cov matrix sparse los yog tsis, peb ua ntej suav cov lej xoom muaj nyob hauv matrix. Ces xam qhov loj ntawm lub matrix. Txhawm rau kom cov matrix tsis sib xws, suav ntawm xoom cov ntsiab lus tam sim no hauv ib qho array yuav tsum ntau dua qhov loj / 2.
Dab tsi yog matrix hauv python?
Sparse matrices tsuas yog ob peb yam uas tsis yog xoom. … Kev khaws cov ntaub ntawv no rau hauv ob-seem matrix cov ntaub ntawv qauv yog qhov chaw pov tseg. Tsis tas li ntawd, nws yog suav hais tias kim heev los sawv cev thiab ua haujlwm nrog cov matrices me me zoo li lawv tuab.
Vim li cas peb thiaj siv sparse matrix?
Siv sparse matrices rau khaws cov ntaub ntawv uas muaj ntau tus lej xoom-tus nqi tuaj yeem txuag tau ntau lub cim xeeb thiab ua kom cov ntaub ntawv ua tiav sparse yog tus cwj pwm uas koj tuaj yeem muab rau ob qhov MATLAB® matrix uas yog tsim los ntawm ob lub ntsiab lus lossis cov laj thawj.
