Joint Learning of Hyperbolic Label Embeddings for Hierarchical Multi-label Classification (2021.eacl-main)
Copied to clipboard
| Challenge: | Existing methods for hierarchical multi-label classification do not assume label hierarchy exists. |
| Approach: | They propose to jointly learn the classifier parameters as well as the label embeddings . they propose to use hyperbolic embeddables to gain better generalisation over the labels . |
| Outcome: | The proposed method achieves state-of-the-art generalization on benchmarks and is more accurate than existing methods. |
Accurate Online Posterior Alignments for Principled Lexically-Constrained Decoding (2022.acl-long)
Copied to clipboard
| Challenge: | Existing methods of offline alignment use only the entire target sentence. |
| Approach: | They propose a posterior alignment technique that is truly online in its execution and superior in terms of alignment error rates compared to existing methods. |
| Outcome: | The proposed technique is online in execution and superior in alignment error rates compared to existing methods. |
