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. The 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. WebNLDA (Sect.3.2). We then describe how we adapt the topic-noise models TND and NLDA to a dynamic setting to produce D-TND (Sect.3.3)andD-NLDA (Sect.3.4). We then propose a method for improving the scalability of dynamic topic models, with the goal of producing dynamic models capable of handling large social media data sets (Sect.3.5). 3.1 Notation orderly thinking
