Seeing the Other Side: Diagnostic Tasks for Viewpoint Reasoning in Vision-Language Models

Towards Automated Lexicography: Generating and Evaluating Definitions for Learner's Dictionaries

This work introduces a reliable evaluation approach for DDG, based on newly proposed evaluation criteria and powered by an LLM-as-a-judge, and proposes an LLM-based LDDG approach that employs iterative simplification.

Doc2FRC: Length-Consistent Document-Level Machine Translation via Fixed-Range Chunking

Experimental results show that FRC-based fine-tuning substantially improves 7B LLMs over direct Doc2Doc fine-tuning and outperforms existing DocMT methods on IWSLT2017.

Cross-Lingual Representation Alignment by Token-Level Optimal Transport in a Language-Agnostic Space

This work proposes CAROT (Cross-Lingual Alignment of Representations in a Language-Agnostic Space via Optimal Transport), which consists of identifying language-specific representations in LLMs'internal states and aligning language-agnostic representations across languages at the token level by optimal transport, while...

Relation Geometry in Semantic Space of Language Models

The results empirically show that relation geometry is not equally well-represented for all relations in semantic space, suggesting that there is a difference in how well semantic relations might be learned from distributional information alone.
