A Unified Neural Coherence Model (D19-1)
Copied to clipboard
| Challenge: | Existing models for coherence modeling fail on harder tasks with more realistic application scenarios. |
| Approach: | They propose a unified coherence model that incorporates sentence grammar, inter-sentence coherent relations, and global coherency patterns into a common neural framework. |
| Outcome: | The proposed model outperforms existing models on local and global discrimination tasks and outperformed existing models by a good margin. |
Randomized Smoothing with Masked Inference for Adversarially Robust Text Classifications (2023.acl-long)
Copied to clipboard
| Challenge: | Large-scale pre-trained language models are brittle against specifically crafted adversarial examples, leading to increasing interest in probing the adversariality of NLP systems. |
| Approach: | They propose a two-stage framework that combines randomized smoothing and masked inference to improve the adversarial robustness of NLP systems. |
| Outcome: | The proposed framework improves adversarial robustness by 2 to 3 times over existing state-of-the-art methods on benchmark datasets. |
