WebJul 2, 2012 · LDA produces a lower dimensional representation of the documents in a corpus. To this low-d representation you could apply a clustering algorithm, e.g. k-means. Since each axis corresponds to a topic, a simpler approach would be assigning each document to the topic onto which its projection is largest.

WebApr 8, 2024 · Latent Dirichlet Allocation (LDA) LDA stands for Latent Dirichlet Allocation. It is considered a Bayesian version of pLSA. In particular, it uses priors from Dirichlet distributions for both the document-topic and word-topic distributions, lending itself to better generalization. It is a particularly popular method for fitting a topic model. reading ladies football team
