DAPO-Math-17k, never-solved problems dropped (Qwen3-1.7B-Base, K=16) The 7,434 problems of the DAPO-Math-17k train set that Qwen3-1.7B-Base solved at least once in K=16 samples — the other 9,964 of 17,398 problems (57.27%), solved 0/16 times, are dropped. In group-relative RL a prompt group whose K responses all score the same has a reward advantage of exactly zero and contributes no gradient. A problem the starting policy solves 0/16 times can only produce such groups, so every… See the full description on the dataset page: https://huggingface.co/datasets/RyanYr/dapo-math-17k-drop-never-solved-qwen3-1.7b-base-k16.
