Document Set Expansion with Positive-Unlabeled Learning Using Intractable Density Estimation (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing approaches to Document Set Expansion (DSE) rely on the unrealistic assumption of knowing the class prior for positive samples in the collection. |
| Approach: | They propose a novel method that utilizes intractable density estimation models to learn the class prior for positive samples in the collection. |
| Outcome: | The proposed method is based on a set of examples from PubMed and Covid datasets in a transductive setting. |
