RACER: Reflective Agent Coupling Query Interpretation and Tool-Based Retrieval for Frame Selection in Long Video Understanding

Video large language models (Vid-LLMs) excel at diverse video-language tasks by reasoning over selected frames. However, frame selection for long videos remains challenging, as it requires retrieving relevant frames distributed across segments from a large candidate pool given complex queries. This paper investigates d...

Random Sparse Networks Training with Sharpness-Aware Regularization.

This study examines a complementary perspective on LTH and proposes the Dual Lottery Ticket Hypothesis (DLTH), enabling general training for sparse networks and introduces Sharpness-Aware Random Sparse Network Transformation (SA-RST), which uses a regularization term to extrude information from weights slated for maski...

Beyond Atomic Layouts: Compositional Design Understanding with Vision-Language Models

A post-training paradigm that integrates multimodal alignment (MA) and structural perception (SP) is proposed, MA enhances element interpretation by grounding metadata-defined elements to their visual counterparts, mitigating semantic drift, and SP models layer-aware inter-element spatial relationships to improve hiera...
