Indlela zelwe: iintlobo eziphambili ubuchule kunye azo

Inani elikhulu iingxaki zezibalo ezinxulumene ekufumaneni ulwazi asasazwa edyokhweni esithubeni. Sithetha iinkqubo zolwazi nokuqwalasela kwimimandla, kuba kuzo kunokwenzeka ukuba umlinganiselo amaxabiso ezifunekayo kwiindawo ezithile. Ukusombulula ezi ngxaki badla usebenzise enye okanye enye indlela zelwe.

definition

Zelwe yindlela yokubala amaxabiso eziphakathi ukuba amaxabiso ukuba iseti ekhoyo imilinganiselo ekhethekileyo. Eyona ndlela iqhelekileyo zelwe zezi zilandelayo: Indlela bemfuno eguqulweyo ngokubaxwa i umgama, umphezulu mkhuba kanye kriging.

iindlela ezisisiseko zelwe

Ngenxa yoko, sihlolisise indlela yokuqala, umongo walo ilele yempembelelo iingongoma isondele isizalwane kuqikelelwa kwindawo ngakumbi. Nala indlela zelwe ibandakanya ukukhethwa ukusuka mphandle kwindawo ethile yencopho elithile, eba negalelo elikhulu kuyo. Ngaloo ekhethiweyo ophezulu uluhlu lokukhangela okanye inani leendawo ukuba zibekwe kufutshane kwindawo ethile. kohlengahlengiso okunene uphiwa ngaye ubunzima kwingongoma ethile nganye, nto leyo ebalwa ngokungqinelana umgama ukusuka kwindawo elinikiweyo. Kuphela ngale ndlela nga kuphunyezwa njengomnikelo enkulu indawo ekufutshane ukuphakama uthathwa xa kuthelekiswa iingongoma ezikude kude elimisiweyo.

Indlela zelwe yesibini kusetyenziswa xa kukho umdla kubaphandi jikelele trends kumphezulu. Ngokufanayo ukuba indlela yokuqala trend indawo lungasetyenziswa, abangaphakathi kumphezulu kwangaphambili. Apho ukwakha iqashiso kelelo kakhulu zisekelwe phezu zezibalo (polynomials okanye splines). Ngokubanzi, sebenzisa indlela izikwere ubuncinane ngokusekelwe kwizibalo ze izixhomekeki nonlinear. Le ndlela isekelwe kokutshintsha amagophe kunye nezinye iintlobo ulandelelwano lwamanani oyibhalayo ezilula. Ukwakha umkhuba ixabiso ngalinye umphezulu kufuneka itshintshwe kule nxaki. Isiphumo lixabiso ekhethekileyo eyabelwe ukuba isisombululo uthathwa (point). Ngokuba zonke ezinye izimvo inkqubo iyaqhubeka.

Enye indlela zelwe ngasentla, inkqubo zelwe kriging unika ifoun, ngokuthatha njengesiseko uhlobo manani kumphezulu.

Ukusebenzisa zelwe equation

Kukho esinye isixhobo ukufumanisa iingongoma ezithile - indlela zelwe equation, eli yona ukutshintshwa komsebenzi kwi ixesha elithile a parabola equation. Ngaloo extremum yayo sibalwa ngokucophelela. Emva indawo yakhe omalunga (lincinane okanye maximum) kufuneka wamisela lokuphumla ethile imilinganiselo, uze ukhangele ukuba ekufumaneni isisombululo ukuba uqhubeke. Ngokwenza le nkqubo kwakhona, ukuba kunokwenzeka, kusetyenziswa inkqubo phindo ukucokisa ixabiso alenxaki isiphumo kunye ngokuchanekileyo kwangaphambili kuloo kuqulunqo ingxaki.
