| |
| This dataset is a curated subset of the original [AI-MO/NuminaMath-1.5](https://huggingface.co/datasets/AI-MO/NuminaMath-1.5) dataset. It has been filtered to create a high-quality corpus of human-authored, validated math problems suitable for training and evaluating language models on mathematical reasoning. |
|
|
| ## Filtering Criteria |
|
|
| This subset was created by applying the following conditions to the 'train' split of the original dataset: |
|
|
|
|
| * **Valid Problems:** Includes only problems marked as complete and well-formed. |
| * **Human-Authored Content Only:** Excludes all synthetically generated problems. |
| * **Cleaned Text:** Removed all entries containing URLs, file links, or markdown images. |
|
|
|
|
| ## Data Fields |
|
|
| The data fields are inherited from the original dataset and include: |
|
|
| * `problem`: The mathematical problem statement in LaTeX. |
| * `solution`: A step-by-step, Chain-of-Thought style solution. |
| * `answer`: The final answer to the problem. |
| * `problem_type`: The mathematical domain (e.g., Algebra, Geometry). |
| * `question_type`: The style of the problem (e.g., proof, math-word-problem). |
| * `source`: The origin of the problem (e.g., olympiads, cn\_k12). |
