EuroBERT: Scaling Multilingual Encoders for European Languages

Nicolas Boizard, Hippolyte Gisserot-Boukhlef, Duarte M. Alves +16

General-purpose multilingual vector representations, used in retrieval, regression and classification, are traditionally obtained from bidirectional encoder models. Despite their w…

On the Rejection Criterion for Proxy-based Test-time Alignment

Ayoub Hammal, Pierre Zweigenbaum, Caio Corro

Recent works proposed test-time alignment methods that rely on a small aligned model as a proxy that guides the generation of a larger base (unaligned) model. The implicit reward a…

Suffix-Constrained Greedy Search Algorithms for Causal Language Models

Ayoub Hammal, Pierre Zweigenbaum, Caio Corro

Large language models (LLMs) are powerful tools that have found applications beyond human-machine interfaces and chatbots. Beside free-form generation, there has been an interest i…

Kad: A Framework for Proxy-based Test-time Alignment with Knapsack Approximation Deferral

Ayoub Hammal, Pierre Zweigenbaum, Caio Corro

Several previous works concluded that the largest part of generation capabilities of large language models (LLM) are learned (early) during pre-training. However, LLMs still requir…

Few-Shot Domain Adaptation for Named-Entity Recognition via Joint Constrained k-Means and Subspace Selection

Ayoub Hammal, Benno Uthayasooriyar, Caio Corro

Named-entity recognition (NER) is a task that typically requires large annotated datasets, which limits its applicability across domains with varying entity definitions. This paper…
