Vektorių kvantavimo metodų ir daugiamačių skalių junginys daugiamačiams duomenims vizualizuoti

Informacijos Mokslai, 2009
Darbe pateikiama lyginamoji dviejų vektorių kvantavimo metodų (saviorganizuojančių neuroninių tinklų ir neuroninių dujų) analizė. Neuronai nugalėtojai, kurie gaunami vektorių kvantavimo metodais, yra vizualizuojami daugiamačių skalių metodu.
