| Challenge: | Traditional goal-oriented dialogue systems require annotations which are hard to obtain for every new domain, limiting scalability. |
| Approach: | They propose a data-driven approach to building goal-oriented dialogue systems . they use a seed dialogue simulator to generate annotated conversations instead of collecting annotations . |
| Outcome: | The proposed system improves turn-level action signature prediction accuracy by 50% . the system is scalable, extensible and data efficient . |
MockingBERT: A Method for Retroactively Adding Resilience to NLP Models (2022.coling-1)
Copied to clipboard
| Challenge: | Existing remediations have compromised accuracy or required full model re-training with each new class of attacks. |
| Approach: | They propose a method of retroactively adding resilience to misspellings to transformer-based NLP models and propose generating adversarial misspells using an approximate method. |
| Outcome: | The proposed method significantly reduces the cost needed to evaluate a model’s resilience to adversarial attacks. |
