Interpolation nzira: pemarudzi chikuru algorithms uye computational

A chinokosha Nhamba kwemasvomhu matambudziko chokuita nokuwana ruzivo richiparadzirwa vanoiswa ari muchadenga. Tiri kutaura mashoko mugadziriro nenzvimbo pfungwa, nekuti maari zvinoita kuyera kunodiwa zvinokosheswa pane dzimwe pfungwa. Kugadzirisa matambudziko aya kakawanda vanoshandisa rimwe kana rimwe nzira interpolation.

tsananguro

Interpolation inzira pakuverenga zvenguva tsika kuti tsika kuti iripo iine discrete tsika. Vakawanda nzira interpolation ndeinotevera: Method pamusoro Ivan Kuchin weighted nechokure, zvinenge nomumativi kriging.

Basic nzira interpolation

Saka, tikanyatsoongorora nzira yokutanga, ayo chaizvoizvo riri pokudzora pfungwa dziri pedyo Zvinofungidzirwa hama kuti nzvimbo mberi. With nzira interpolation kwakadaro kunosanganisira kusarudzwa kubva kwakaita nzvimbo yacho pane imwe pedyo nezverimwe, ane mukuru simba pairi. Saka akasarudza kunonyanyisa kutsvaka siyana kana uwandu pfungwa kuti dziri pedyo imwe pfungwa. Uyezve kuchinja kunopiwa kurema neimwe Kunyanya pfungwa, izvo rinowanikwa maererano kure rakapihwa pfungwa. Chete nenzira iyi inogona kubudirira nokupa chikuru pedyo pfungwa iri interpolated kukwirira kana zvichienzaniswa pfungwa kure yakatarwa.

Chechipiri interpolation nzira inoshandiswa kana pane kufarira nevaongorori vakawanda kuitika pamusoro. Saizvozvowo nzira yokutanga kuti muitiro pfungwa angashandiswa, izvo mukati akafanorongerwa pemvura. Apo ukavaka yakawanda rakada akanakisisa inobva kwemasvomhu equations (polynomials kana splines). Kazhinji, kushandisa nzira wevadukusa dzinoungana kwakavakirwa equations ose nonlinear dependencies. Nzira inobva kutsiva makakombama nezvimwe kusanganiswa sequences kutaipa nyore. Gadzirisa muitiro nerimwe kukosha pamusoro inofanira kuchiiswa mu mukana wokuti vanhu vanga. Zvinoguma rakasiyana ukoshi akatumirwa interpolated mhinduro (pfungwa). Nokuti zvose dzimwe pfungwa kwacho kunopfuurira.

Chimwe interpolation nzira kumusoro, kriging interpolation nzira inopa nokuda Optimization, achitora sezvikonzero ari Statistical hunhu pemvura.

Kushandisa quadratic interpolation

Pane imwe mudziyo kuti kuona zvariri pfungwa - nzira yokutambidza quadratic interpolation, musimboti unova yokutsiva ane mashandiro pane imwe nguva mumwe quadratic parábola. Saka kwayo Extremum rinowanikwa analytically. Pashure ake anofungidzirwa nzvimbo (Minimum kana kunonyanyisa) anofanira kuiswa mumwe penguva tsika, uye ipapo kutsvaka kuwana mhinduro mberi. Nokuita nzira iyi zvakare, zvinokwanisika, achiedza iterative nzira kunatsiridza kukosha mukana wokuti vanhu vanga ichi kuti mugumisiro pamwe akafanorongerwa zvakarurama dambudziko Pfungwa.
