Many uncertainty quantification (UQ) methods can flag such output, but the strongest ones sample the model repeatedly and are expensive. Density-based scores such as Mahalanobis Distance (MD) are cheap and work well for encoder classifiers, yet earlier… 2. **[Unconditional Truthfulness: Learning Unconditional Uncertainty of Large Language Models](https://md.research.elamur.ai/free/en/papers/vazhentsev-2025-unconditional-truthfulness-learning-unconditional-uncertainty/)** *(2025 · 10 citations)* LLMs score each new token assuming everything generated so far is correct. If an early token is wrong, the tokens that follow can still look highly confident, so uncertainty estimates built on raw probabilities understate the risk. The authors argue that what matters is a token's unconditional chance of being… ## Co-authors here 10 co-authors with a page, the most papers together first. - [Alexander Panchenko](https://md.research.elamur.ai/free/en/authors/alexander-panchenko/) ×2 - [Artem Shelmanov](https://md.research.elamur.ai/free/en/authors/artem-shelmanov/) ×2 - [Artem Vazhentsev](https://md.research.elamur.ai/free/en/authors/artem-vazhentsev/) ×2 - [Maxim Panov](https://md.research.elamur.ai/free/en/authors/maxim-panov/) ×2 - [Timothy Baldwin](https://md.research.elamur.ai/free/en/authors/timothy-baldwin/) ×2 - [Ekaterina Fadeeva](https://md.research.elamur.ai/free/en/authors/ekaterina-fadeeva/) - [Gleb Kuzmin](https://md.research.elamur.ai/free/en/authors/gleb-kuzmin/) - [Lyudmila Rvanova](https://md.research.elamur.ai/free/en/authors/lyudmila-rvanova/) - [Preslav Nakov](https://md.research.elamur.ai/free/en/authors/preslav-nakov/) - [Rui Xing](https://md.research.elamur.ai/free/en/authors/rui-xing/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2025](https://md.research.elamur.ai/free/en/venues/emnlp/2025/) - [Conference of the North American Chapter of the Association for Computational Linguistics (NAACL)](https://md.research.elamur.ai/free/en/venues/naacl/): [NAACL 2025](https://md.research.elamur.ai/free/en/venues/naacl/2025/) ## Cited by Papers of our library cite their works 20 times (of the 149,439 papers whose bibliographies we read); [8 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/ivan-lazichny/cited-by/).
