WebTopic modeling can be used to classify or summarize documents based on the topics detected or to retrieve information or recommend content based on topic similarities. The topics from documents that NTM learns are characterized as a latent representation because the topics are inferred from the observed word distributions in the corpus. WebJul 2, 2024 · E.g., in topic A the words “data”, “machine”, and “algorithm” are the most common, while in topic C the most common words are “homework”, “grade”, and “task” - the word “solution” is equally likely in both topics. In contrast to LDA, CTM allows the topics to be correlated. Both model types are implemented in the R ...

The CTM is fully described in Blei and Lafferty (2007). (For an implementation of a related topic model, latent Dirichlet allocation, click here .)
WebFeb 18, 2024 · Topic Modeling with LDA Before training our CTM model, we need to extract the topics and their proportions in each game description by training an LDA model. The first thing we do is to lemmatize game descriptions to reduce variance in the vocabulary and improve LDA estimates.
