For temporal modeling we associate each topic with a time-dependent function that characterizes its popularity over time. By integrating the two models, we ...
This paper proposes a new methodology to study sequential corpora by implementing a two-stage algorithm that learns time-based topics with respect to a scale ...
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 ...
Feb 7, 2024 · Abstract—In this paper, we propose the Continuous Time. Fractional Topic Model (cFTM), a new method for dynamic topic modeling.
In this paper, we propose two models to detect communities by considering both topic and dynamic features.
