The rapid advancements in Artificial Intelligence (AI), particularly in generative AI and foundational models (FMs), have ushered in transformative changes across various industries.

Sparse Parallel Training of Hierarchical Dirichlet Process Topic Models

1 code implementation EMNLP 2020 Alexander Terenin, Måns Magnusson, Leif Jonsson

To scale non-parametric extensions of probabilistic topic models such as Latent Dirichlet allocation to larger data sets, practitioners rely increasingly on parallel and distributed systems.

Sparse Partially Collapsed MCMC for Parallel Inference in Topic Models

1 code implementation11 Jun 2015 Måns Magnusson, Leif Jonsson, Mattias Villani, David Broman

We propose a parallel sparse partially collapsed Gibbs sampler and compare its speed and efficiency to state-of-the-art samplers for topic models on five well-known text corpora of differing sizes and properties.
