The proposed Gravitation Model. Hauv seem no, tus qauv tshiab Centroid-Based Classification Model, piv txwv li, Gravitation Model (GM), tau qhia kom yooj yim kov yeej qhov tsis txaus ntseeg (lossis kev tsis ncaj ncees) ntawm CBC hauv chav kawm-cov ntaub ntawv tsis sib npaug.
Centroid raws pawg yog dab tsi?
Centroid-raws li pawg npaj cov ntaub ntawv mus rau hauv pawg tsis yog hierarchical, sib piv rau hierarchical pawg txhais hauv qab no. k-txhais tau tias yog qhov siv dav tshaj plaws centroid-based clustering algorithm. Centroid-based algorithms yog qhov ua tau zoo tab sis nkag siab rau cov xwm txheej thawj zaug thiab qhov tsis zoo.
Kev ntsuas tus qauv raws li kev txheeb xyuas yog dab tsi?
qauv-raws li kev txheeb xyuas pawg yog txheej txheem tshiab pawg los tshawb xyuas cov pej xeem heterogeneity siv cov sib tov sib xyaw ua ke ntau qhov sib txawv ib txwm muaj.
Dab tsi yog kev faib qauv raws li pawg?
Definition. Qauv-raws li pawg yog ib txoj hauv kev txheeb cais rau cov ntaub ntawv pawgCov ntaub ntawv pom (multivariate) yog xav tias tau tsim los ntawm kev sib xyaw ua ke ntawm cov qauv sib xyaw. Txhua tus qauv qauv yog qhov muaj feem cuam tshuam, feem ntau yog parametric multivariate faib.
Dab tsi yog pawg qauv?
Kev tshuaj xyuas pawg, lossis kev sib koom ua ke, yog txoj haujlwm tsis muaj kev saib xyuas tshuab kev kawmNws suav nrog kev cia siab nrhiav pom kev ua pawg hauv cov ntaub ntawv. Tsis zoo li kev saib xyuas kev kawm (xws li kev kwv yees ua qauv), pawg algorithms tsuas yog txhais cov ntaub ntawv nkag thiab nrhiav cov pab pawg lossis pawg hauv qhov chaw tshwj xeeb.
