Kev kaw qhov nruab nrab yog qhov ntsuas ntawm qhov nruab nrab luv tshaj plaws ntawm txhua qhov vertex mus rau ib leeg vertex. Tshwj xeeb, nws yog qhov hloov pauv ntawm qhov nruab nrab luv tshaj plaws ntawm qhov vertex thiab tag nrho lwm cov vertices hauv lub network. Tus qauv yog 1 / (nruab nrab nrug rau tag nrho lwm cov vertices).
Dab tsi yog kev sib raug zoo hauv nruab nrab?
Kev sib raug zoo hauv nruab nrab yog kev ntsuas muaj txiaj ntsig uas kwv yees qhov nrawm npaum li cas ntawm cov ntaub ntawv yuav dhau los ntawm ib qho muab rau lwm cov nodes. Daim duab 28 Kev xam qhov ze nruab nrab ntawm cov nodes hauv daim duab.
Dab tsi yog qhov kev sib raug zoo hauv nruab nrab?
Kev sib raug zoo hauv nruab nrab yog ib txoj hauv kev tshawb xyuas cov nodes uas muaj peev xwm nthuav tawm cov ntaub ntawv veryua tau zoo los ntawm daim duab. Qhov ze ze nruab nrab ntawm ib lub node ntsuas nws qhov nruab nrab farness (inverse nrug) rau tag nrho lwm cov nodes. Cov nodes nrog cov qhab nias siab siab muaj qhov luv tshaj plaws rau tag nrho lwm cov nodes.
Koj suav qhov nruab nrab li cas?
Xaiv nruab nrab ntawm qhov nruab nrab, koj coj txhua khub ntawm lub network thiab suav pes tsawg zaus ib lub node tuaj yeem cuam tshuam txoj kev luv tshaj plaws (geodesic nrug) nruab nrab ntawm ob qhov ntawm khub.
Centrality thiab closeness centrality yog dab tsi?
Ntawm nruab nrab ntawm qhov nruab nrab feem ntau suav tias yog kev ntsuas ntawm lwm tus 'kev vam khom rau ntawm ib qho muab, thiab yog li kev ntsuas ntawm kev tswj tau. Closeness centrality feem ntau yog txhaisxws li kev ntsuas kev nkag mus tau zoo lossis kev ywj pheej los ntawm kev tswj xyuas los ntawm cov neeg nruab nrab.
