Polaris-Filtered Nemotron Easy Math (Verifiable)

A filtered subset of nvidia/Nemotron-Math-v2 (low / easy split), retaining only non-TIR samples with verifiable boxed answers.

Filtering Pipeline

1.Remove TIR / tool-use samples — drop any sample that contains Python code blocks (\\\python, <|pythonstart|>`, `<toolcall>) or has a non-empty tools/tool` field.
2.Polaris decontamination — remove samples whose user prompt shares any 15-gram overlap with problems in POLARIS-Project/Polaris-Dataset-53K.
3.Answer verification — keep only samples where the \boxed{} answer in the assistant response matches the expected_answer field (verified via math-verify).
