Existing data-efficient evaluation methods usually rely on many prior model results, which a newly added benchmark does not have. SubLIME, from Hewlett Packard Labs, addresses this cold-start case. It picks a small subset, 1–20% of a benchmark's… 2. **[CEBC: Conformal Evidence-Bounded Control for Low-Hallucination Vision–Language Generation](https://md.research.elamur.ai/free/en/papers/mishra-2026-cebc-conformal-evidence-bounded-control/)** *(2026)* Vision–language models often mention objects that are not in the image. Existing remedies tend either to make outputs vaguer or to require costly retraining. The Hewlett Packard Labs authors propose CEBC, a post-generation layer that works with any VLM and needs no training. It first produces a small pool of… ## Co-authors here 2 co-authors with a page, the most papers together first. - [Martin Foltin](https://md.research.elamur.ai/free/en/authors/martin-foltin/) ×2 - [Tarun Kumar](https://md.research.elamur.ai/free/en/authors/tarun-kumar/) ×2 ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/), [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ## Cited by Papers of our library cite their works 4 times (of the 149,439 papers whose bibliographies we read).
