Close or Cloze? Assessing the Robustness of Large Language Models to Adversarial Perturbations via Word Recovery
Conference Proceedings International Conference on Computational Linguistics Coling · January 1, 2025 The current generation of large language models (LLMs) show a surprising degree of robustness to adversarial perturbations, but it is unclear when these models implicitly recover the original text and when they rely on surrounding context. To isolate this ... CiteTO TRUST OR NOT TO TRUST? ENHANCING LARGE LANGUAGE MODELS' SITUATED FAITHFULNESS TO EXTERNAL CONTEXTS
Conference 13th International Conference on Learning Representations Iclr 2025 · January 1, 2025 Large Language Models (LLMs) are often augmented with external contexts, such as those used in retrieval-augmented generation (RAG). However, these contexts can be inaccurate or intentionally misleading, leading to conflicts with the model's internal knowl ... CiteReal-time Factuality Assessment from Adversarial Feedback
Conference Proceedings of the Annual Meeting of the Association for Computational Linguistics · January 1, 2025 We show that existing evaluations for assessing the factuality of news from conventional sources, such as claims on fact-checking websites, result in high accuracies over time for LLM-based detectors-even after their knowledge cutoffs. This suggests that r ... CiteRecent Grants
