Web8 apr. 2024 · A Little Background about LDA Latent Dirichlet Allocation (LDA) is a popular topic modeling technique to extract topics from a given corpus. The term latent conveys something that exists but is not yet developed. In other words, latent means hidden or concealed. Now, the topics that we want to extract from the data are also “hidden topics”. Web11 apr. 2024 · NLP Algorithm Engineer - TikTok e-Commerce. about 2 months ago. Singapore.

Topic … In natural language processing, Latent Dirichlet Allocation (LDA) is a generative statistical model that explains a set of observations through unobserved groups, and each group explains why some parts of the data are similar. The LDA is an example of a topic model. In this, observations (e.g., words) are collected into documents, and each word's presence is attributable to one of the document's topics. Each document will contain a small number of topics.
