SignalReasoner: Assessing the Upper Bound of 3B Models for Signal Mathematical Reasoning

ai-technology · 2026-08-19

The paper titled "SignalReasoner" evaluates the upper limit of 3B models in the realm of signal mathematical reasoning, specifically targeting graduate-level challenges. Published as arXiv:2608.17301, it employs Qwen2.5-3B-Base as the foundational model and utilizes the WirelessMATHBench-XL benchmark. The research investigates two training strategies: direct reinforcement learning (RL) and supervised fine-tuning (SFT) followed by RL. Additionally, it assesses GRPO, GSPO, and Geometric-Mean Policy Optimization. This study highlights a significant gap in the exploration of RL applications within signal processing.
