HyHTM: Hyperbolic Geometry-based Hierarchical Topic Model (2023.findings-acl)
Copied to clipboard
| Challenge: | Hierarchical Topic Models (HTMs) often produce hierarchies where lower-level topics are unrelated and not specific enough to their higher-level subjects. |
| Approach: | They propose a Hyperbolic geometry-based Hierarchical Topic Model that incorporates hierarchical information from hyperbolic geometrics to explicitly model hierarchies in topic models. |
| Outcome: | The proposed model is significantly faster and leaves a much smaller memory footprint than the best-performing baseline. |
