• Abstract: Topic models are a popular approach for extracting semantic information from large document collections. However, recent studies suggest that the topics generated by these models often do not align well with human intentions. While metadata such as labels and authorship information is available, it has not yet been effectively incorporated into neural topic models. To address this gap, we introduce FANToM, a novel method for aligning neural topic models with both labels and authorship information. FANToM allows for the inclusion of this metadata when available, producing interpretable topics and author distributions for each topic. Our approach demonstrates greater expressiveness than conventional topic models by learning the alignment between labels, topics, and authors. Experimental results show that FANToM improves upon existing models in terms of both topic quality and alignment. Additionally, it identifies author interests and similarities.

• Federated Neural Topic Models [0.0]
  Federated topic modeling allows multiple parties to jointly train a topic model without sharing their data. We propose and analyze a federated implementation based on state-of-the-art neural topic modeling implementations. In practice, our approach is equivalent to a centralized model training, but preserves the privacy of the nodes.
