Urejenostne strukture v analizi podatkov : magistrsko deloZaveršnik, MatjažV uvodnem poglavju so obdelane teoretične osnove o urejenostnih strukturah, ki najpogosteje nastopajo v analizi podatkov. Predstavljeni so tisti rezultati o njih, ki so potrebni pri obravnavi v ... naslednjih poglavjih. V drugem poglavju je predstavljen problem razvrščanja v skupine. Poudarek je na strukturah množic razvrstitev in ostalih modelov razvrščanja (ultrametrike, dendrogrami, hierarhije, ...). Na koncu je predstavljena še povezava s teorijo konsenza. Tretje poglavje opisuje bločne modele. Poudarek je na različnih vrstah enakovrednosti, med katerimi izstopajo predvsem regularne in strukturne. Pokazano je, da so množice enakovrednosti iste vrste polne mreže. Vsa teorija je prevedena še v jezik barvanja grafov. V delu so poleg regularnih in strukturnih barvanj opisana še avtomorfna, ekološka in popolna barvanja. Četrto poglavje je posvečeno analizi konceptov. Najprej je podan dokaz, da je množica vseh konceptov danega konteksta polna mreža, nato pa so še opisani postopki, s pomočjo katerih poiščemo vse te koncepte. Opisani so tudi večvrednostni konteksti in način njihove pretvorbe v običajne kontekste. Izdelanih je že nekaj računalniških programov, ki so namenjeni slikovni predstavitvi konceptualnih mrež. V delu so omenjeni nekateri izmed njih, opisana pa so tudi pravila, ki nam omogočajo branje izdelanih slikovnih predstavitev.Type of material - master's thesisPublication and manufacture - Ljubljana : [M.
