GRPO foregoes the critic model, instead estimating the baseline from group scores, significantly
reducing training resources. By solely using a subset of English instruction tuning data, GRPO
obtains a substantial improvement over the strong DeepSeekMath-Instruct, including both
in-domain (GSM8K: 82.9% → 88.2%, MATH: 46.8% → 51.7%) and out-of-domain mathematical
tasks (e.g., CMATH: 84.6% → 88.8%) during the reinforcement learning phase
> Similarly, for code competition prompts, a compiler can be utilized to evaluate the model’s responses against a suite of predefined test cases, thereby generating objective feedback on
correctness
None of those are novel domains w/ their own novel syntax & semantic validators, not to mention the dearth of readily available sources of examples for sampling the baselines. So again, where does it say it works for a programming language with nothing but a grammar & a compiler?
Bring up passage that supports your claim. I'll wait.
Not exactly sure what you are looking for here.
That GRPO works?
