LexFit: Lexical Fine-Tuning of Pretrained Language Models (2021.acl-long)
Copied to clipboard
| Challenge: | Transformer-based language models implicitly store a wealth of lexical semantic knowledge, but it is non-trivial to extract that knowledge effectively from their parameters. |
| Approach: | They propose to expose and enrich lexical knowledge from transformer-based language models to serve as effective decontextualized word encoders even when fed input words "in isolation" |
| Outcome: | The proposed model outperforms standard static WEs and vanilla LMs in lexical tasks over four established tasks in 8 languages. |
Robust Text Classification: Analyzing Prototype-Based Networks (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Language models exhibit a drop in performance on noisy data, which can cause classifiers to incorrectly change their predictions. |
| Approach: | They propose to use Prototype-Based Networks to classify examples based on their similarity to prototypical examples of a class (prototypes) they show that PBNs offer more robustness under both targeted and static adversarial attacks. |
| Outcome: | The proposed model is robust to noise and targets both targeted and static attacks. |
