ExecVerify: White-Box RL with Verifiable Stepwise Rewards for Code Execution Reasoning (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods for code execution reasoning are limited by the difficulty of the training data. |
| Approach: | They propose a model that uses reinforcement learning to reward correct answers from execution traces. |
| Outcome: | The proposed model improves pass@1 by up to 5.9% on code generation tasks over strong baselines. |
VividMed: Vision Language Model with Versatile Visual Grounding for Medicine (2025.naacl-long)
Copied to clipboard
| Challenge: | Vision Language Models (VLMs) have demonstrated promise in generating visually grounded responses, but their application in the medical domain is hindered by unique challenges. |
| Approach: | They propose a vision language model with versatile visual grounding for medicine that generates semantic segmentation masks and instance-level bounding boxes. |
| Outcome: | The proposed model can generate semantic segmentation masks and instance-level bounding boxes, and accommodates various imaging modalities, including both 2D and 3D data. |
