Copied to clipboard
| Challenge: | Existing methods for topic modelling on unbalanced data contain topics in various proportions and documents of the relatively small theme become distributed all over the larger topics instead of being grouped into one topic. |
| Approach: | They propose a new regularizer for topic models on unbalanced data collections . they make sure this regularizer increases the quality of topic models, trained on unstructured data . |
| Outcome: | The proposed method improves the quality of topic models trained on unbalanced datasets. |
