NuminaMath-1.5-proofs-only-strict

A strictly filtered version of the NuminaMath-1.5-proofs-only dataset, containing ONLY validated mathematical proof problems.

📊 Filtering Results

• Original dataset: Numina1.5 -> filter for proofs -> 110,998 rows

• Filters applied:

  • ✓ Kept rows where answer = "proof" (proof problems only)
  • ✓ Kept rows where solution_is_valid = "Yes"
  • ✓ Kept rows where problem_is_valid = "Yes"
  • ✓ Dropped validation columns after filtering

• Filtered dataset: 58,088 rows (removed 52,910 rows)

📦 Dataset

• Columns preserved:
  • problem - The mathematical problem statement requiring a proof
  • solution - Step-by-step proof/solution
  • answer - Always "proof" (filtered to contain only proof problems)
  • problem_type - Type of mathematical problem
  • question_type - Question format/style
  • source - Original source of the problem
  • synthetic - Whether the problem is synthetically generated
  • source_dataset - Source dataset identifier
  • source_split - Dataset split (train/test/val)

This strict version contains only validated mathematical proof problems, perfect for training models on formal mathematical reasoning and proof generation.
