Lens: Bringing the Right Semantic Perspective into Focus for Training-Free Multimodal Representation Learning

Lens is a training-free framework that makes representation readout task-directed, and achieves an overall Precision@1 of 63.9 across all 36 MMEB datasets, outperforming the closest same-backbone training-free embedding baseline by 10.2 points.

IRIS: Reusable Identity Representations from Frozen LLMs for Entity Alignment

The proposed IRIS (Identity Representations from Internal States), a training-free framework that constructs for each entity an iris-like signature encoding its distinctive and stable identity characteristics, thereby forming a shared space in which each entity is encoded once and can be aligned across different KGs th...

Penelope: Localized Latent Recurrence for Efficient Structured Reasoning

Penelope is introduced, an efficient latent-reasoning framework for pretrained decoder-only Transformers that localizes recurrent computation to a selected decoder interval and attains competitive accuracy relative to established latent-reasoning models while reducing measured inference latency.
