CURIO: Curiosity-Driven Test-Time Learning for Open-Ended Discovery

Open-ended discovery requires learning from repeated attempts while continuing to explore directions whose value is not yet apparent. Search with a frozen large language model (LLM) can reuse previous solutions in context, but cannot update the model from its successes and failures on the test problem. Reinforcement le...

PolyOCR-Venus: Unified OCR Foundation Models for Text-Centric Visual Intelligence

This report presents PolyOCR, a family of unified OCR foundation models of varying scales that combines a shared instruction-following framework with a large-scale data engine that converts heterogeneous visual resources into quality-verified OCR supervision.

UniAR: A Unified Framework for Autism Recognition Enhanced by Multi-View Prompt Learning

UniAR leverages a large multimodal model to generate hierarchical diagnostic descriptions at the word, phrase, and sentence levels, compensating for the lack of paired clinical reports, and demonstrates that it offers a robust and interpretable framework for ASD screening under semantic scarcity.

Evaluating Deep-Search Agents under Hierarchical Web Evidence Poisoning

HAE-GEO is introduced, a benchmark that tracks the full trajectory from exposure to recovery under progressively more persuasive Web poisoning and finds three recurring patterns: evidence recognition degrades under the corroboration trap, agentic search improves final resistance without improving evidence recognition o...

UniMoMo: Expert Merging-Based MoE Acceleration for Large Recommendation Models

UniMoMo, a post-training compression framework formulated as a constrained graph coarsening problem, is introduced, and a layer-adaptive protection mechanism that restricts the merging of high-traffic experts based on their routing exposure is introduced.

Think with Structured Grounding: Perceptual Reinforcement Learning for Chart and Visual-Tabular Understanding

Think with Structured Grounding (TwSG), a novel fine-grained image perception framework designed to internalize complex images's tool-use capabilities within the model, is proposed, endowing models with native fine-grained region description and flexible reasoning capabilities.
