Iterative Improvement of an Additively Regularized Topic Model

2024-08-11 · Alex Gorbulev, Vasiliy Alekseev, Konstantin Vorontsov

Topic modelling is fundamentally a soft clustering problem (of known objects -- documents, over unknown clusters -- topics). That is, the task is incorrectly posed. In particular, the topic models are unstable and incomp…
