Uchambuzi wa Latent Dirichlet (LDA)

Uchambuzi wa Latent Dirichlet (LDA) ni mfumo wa kielelezo wa uzalishaji kwa makusanyo ya data tofauti, ulioanzishwa na Blei, Ng, na Jordan mwaka 2003. Unachukulia kila hati kama mchanganyiko wa mada zilizofichwa na kila mada kama usambazaji wa uwezekano juu ya maneno, kuwezesha ugunduzi usio na usimamizi wa muundo wa mada katika makusanyo makubwa ya maandishi. Ni moja ya machapisho yaliyonukuliwa zaidi katika akili bandia na uchakataji wa lugha asilia.
