Credit-Addressable Reasoning for Multimodal Geometry via Code-CoT
August 30, 2026
Credit-addressable reasoning allows VLMs to assign learning credit to specific semantic units rather than terminal signals. Using Code-CoT and CE-GRPO, the method represents visual relations as line-addressable executable code to improve multi-step geometric deduction.
