Lda algorithm in nlp
Web7 dec. 2024 · LDA, or Latent Dirichlet Allocation, is a generative probabilistic model of (in NLP terms) a corpus of documents made up of words and/or phrases. The model consists of two tables; the first table is the probability of selecting a particular word in the corpus when sampling from a particular topic, and the second table is the probability of selecting a …
