Enhancing Radiology Report Generation and Visual Grounding using Reinforcement Learning

arXiv — cs.CVFriday, December 12, 2025 at 5:00:00 AM
  • Recent advancements in vision-language models (VLMs) have led to the development of RadVLM, which enhances Chest X-ray (CXR) report generation and visual grounding through reinforcement learning (RL) and explicit intermediate reasoning. This approach moves beyond traditional supervised fine-tuning by incorporating task-specific feedback, aiming to improve the quality of medical interpretations.
  • The integration of reinforcement learning in RadVLM represents a significant step forward in medical imaging, as it allows for more accurate and contextually relevant interpretations of CXR data. This could lead to better diagnostic outcomes and more efficient healthcare delivery, addressing critical needs in medical practice.
  • The ongoing exploration of reinforcement learning in VLMs highlights a broader trend in artificial intelligence, where traditional methods are being reevaluated in favor of more dynamic approaches. Issues such as reasoning path failures and the necessity for improved temporal understanding are being addressed across various models, indicating a shift towards more robust and adaptable AI systems in healthcare and beyond.

Surgical Refusal Ablation: Disentangling Safety from Intelligence via Concept-Guided Spectral Cleaning
NeutralArtificial Intelligence
The introduction of Surgical Refusal Ablation (SRA) aims to enhance the safety of language models by refining their refusal capabilities, minimizing collateral damage and distribution drift caused by traditional methods. SRA achieves this by creating a registry of independent Concept Atoms and utilizing ridge-regularized spectral residualization to produce a clean refusal direction.
