Unlocking Spatial Logic Through Executable Programs and Verified Rewards

GeoX operates by employing a single multimodal policy that generates spatial problems in the form of executable programs. These programs are then solved under three distinct reasoning modes, abduction, deduction, and induction, leveraging spatial primitives and an image understanding tool. Crucially, a verifier executes each program, generating a verifiable reward signal. This reward signal then jointly optimizes both the problem-posing and problem-solving roles within the framework via reinforcement learning, creating a virtuous cycle of improvement.

Autonomous Improvement in Geospatial Understanding

The impact of GeoX is substantial. The researchers report that it consistently enhances the performance of base Vision-Language Models (VLMs) by an average of up to 5.5 points. This improvement matches or surpasses conventional baselines that are trained on millions of meticulously curated data points. Alongside the proposed method, the authors are releasing a novel benchmark for geospatial understanding, itself accumulated through this self-play process, offering a new standard for evaluating geospatial reasoning AI capabilities.
