Ring-lite-rl-data

This dataset is a curated subset of high-quality problems across mathematics and code domains designed for reinforcement learning in the Ring-lite model. This dataset contains:

Mathematics: Over 39,000 rigorously curated problems sourced from:
- Open-source datasets (BigMath, DeepScaleR, DAPO, DeepMath-103K)
- Art of Problem Solving (AoPS) contest collections
Code: Approximately 8,400 verified coding problems from:
- Programming competition resources (CodeContest, TACO, APPS)
- All problems include validated "Accepted" solutions and test cases

Note: Only a partial subset of the complete dataset is publicly released due to third-party data licensing restrictions and procurement agreements. The published portion has been carefully selected to comply with all copyright requirements while maintaining research utility.

Dataset Construction

Data Sources

Mathematics: Problems collected from open-source datasets, filtered through strict quality control
Code: Problems from open-source programming competition resources with verified solutions

Curation Pipeline

Our data undergoes a rigorous three-stage curation process:

Data Cleansing:
- Removal of problems with invalid characters, images, or multiple subquestions
- Strict character-based and semantic-based deduplication
- Exclusion of easily guessable problems (multiple-choice, True/False questions)
Answer Verification:
- LLM-based verification using models of different sizes
- Human expert annotation
- Problems failing verification are excluded
Data Annotation:
- Multi-dimensional labeling (source, educational level, domain knowledge)
- Mathematical Subject Classification (MSC) for math problems
- Model-aware difficulty assessment
