Polu-nadgledani NMF model tema

Polu-nadgledani model tema zasnovan na ne-negativnoj faktorizaciji matrica (NMF) proširuje nenadgledani NMF uključivanjem korisnički datih početnih reči ili ograničenja oznaka kako bi se otkrivene teme usmerile ka domen-relevantnim konceptima. On faktorizuje matricu dokument-pojam u interpretativne ne-negativne komponente, poštujući leksičke apriorne vrednosti, dajući koherentne, aplikaciono usklađene teme čak i iz skromnih korpusa.
