Don't Just Encode But See: A Data-Centric Paradigm for Visual Molecular Understanding in Large Language Models

Large language models (LLMs) are rapidly becoming interactive scientific assistants. Most existing pipelines rely on specialized molecular encoders and alignment modules, while overlooking the importance of chemical hierarchy and traceable evidence for reliable reasoning and explanation. Thus, we propose MolGlass, a da...

RePair: Turning Retrieval Failures into Counterfactual Hard Pairs

RePair is introduced, guided by three principles---Validity, Minimality, and Locality---which mines false positives bidirectionally, applies LLM-guided counterfactual editing, and trains with a local hard-pair contrastive objective.

From Saliency to Discriminability: Rank-Preserving Visual Token Pruning for VLM Rerankers

Large vision-language models used as listwise rerankers must jointly process visual tokens from tens of candidates per query, making token pruning essential for practical deployment. Existing pruning methods retain tokens by attention saliency, yet we show that saliency is systematically misaligned with ranking contrib...

M²DDI: A Unified Framework for Dynamic Multimodal Fusion in Drug-Drug Interaction Prediction

Empirical evaluation and robustness experiments show that M2DDI maintains high predictive accuracy even when modality-specific information is partially missing, outperforming existing methods under similar conditions and establish M2DDI as an effective and mechanism-aware solution for comprehensive DDI prediction.

EviRank: Structured Relevance Evidence for Multimodal Image Re-ranking

EviRank is recast multimodal image re-ranking as a semantic constraint satisfaction problem and proposed, which parses any query - text-only, image-only, or composed - into a unified evidence package: typed criteria across six semantic slots, each labelled required, forbidden, or ignorable.

Don't Just Encode But See: A Data-Centric Paradigm for Visual Molecular Understanding in Large Language Models

MolGlass is proposed, a data-centric paradigm for visual molecular understanding in vision-language models (VLMs) that injects chemical priors directly into the visual input through chemical-aware visual augmentations, without modifying model architectures or training molecule-specific encoders.
