NMF modeliranje tema

NMF modeliranje tema koristi faktorizaciju nenegativnih matrica — dekompoziciju utemeljenu na dijelovima koju su uveli Lee i Seung (1999) — za ekstrakciju distribucija dokumenata i tema iz korpusa. Faktorizacijom matrice dokumenata i termina u dvije nenegativne matrice, ona obnavlja mali skup tema i teži proizvesti interpretativnije teme od LDA.
