WebIn the machine learning subfield of Natural Language Processing (NLP), a topic model is a type of unsupervised model that is used to uncover abstract topics within a corpus. Topic modelling can be thought of as a sort of soft clustering of documents within a corpus. Dynamic topic modelling refers to the introduction of a temporal dimension into ...

WebJun 13, 2012 · Download PDF Abstract: In this paper, we develop the continuous time dynamic topic model (cDTM). The cDTM is a dynamic topic model that uses Brownian motion to model the latent topics through a sequential collection of documents, where a "topic" is a pattern of word use that we expect to evolve over the course of the collection.
WebDynamic topic models (DTM) captures the evolution of topics in a sequentially organized movies. In the DTM, we divide the data by time slice, e.g., by year. We model the movies of each slice with a K-component topic model, where the topics associated with slice t evolve from the topics associated with slice t-1.
