Not All Tokens See Equally: Perception-Grounded Policy Optimization for Large Vision-Language Models

Researchers introduce Perception-Grounded Policy Optimization (PGPO), a novel fine-tuning framework that improves how large vision-language models learn from visual inputs by strategically allocating learning signals to vision-dependent tokens rather than treating all tokens equally. Testing on the Qwen2.5-VL series demonstrates an average 18.7% performance boost across multimodal reasoning benchmarks.

Asking like Socrates: Socrates helps VLMs understand remote sensing images

Researchers introduce RS-EoT (Remote Sensing Evidence-of-Thought), a novel framework that enables vision-language models to reason more effectively about satellite imagery by iteratively seeking visual evidence rather than relying on linguistic patterns. The approach uses a self-play multi-agent system called SocraticAgent and reinforcement learning to address the 'Glance Effect,' where models superficially analyze large-scale remote sensing images, achieving state-of-the-art performance on multiple benchmarks.

InterChart: Benchmarking Visual Reasoning Across Decomposed and Distributed Chart Information

Researchers introduce InterChart, a benchmark designed to evaluate how well vision-language models (VLMs) reason across multiple related charts—a capability essential for financial analysis, scientific reporting, and policy dashboards. Testing reveals that state-of-the-art VLMs struggle significantly as chart complexity increases, performing better when multi-entity charts are decomposed into simpler components, highlighting a critical gap in multimodal reasoning capabilities.

Visually-Guided Policy Optimization for Multimodal Reasoning

Researchers propose Visually-Guided Policy Optimization (VGPO), a framework that enhances vision-language models' ability to focus on visual information during reasoning tasks. The method addresses a fundamental limitation where text-dominated VLMs suffer from weak visual attention and temporal visual forgetting, improving performance on multimodal reasoning and visual-dependent tasks.

Don't Blink: Evidence Collapse during Multimodal Reasoning

Research reveals that Vision Language Models (VLMs) progressively lose visual grounding during reasoning tasks, creating dangerous low-entropy predictions that appear confident but lack visual evidence. The study found attention to visual evidence drops by over 50% during reasoning across multiple benchmarks, requiring task-aware monitoring for safe AI deployment.
