Training Data Sources

Overview

The Grogu Science MoE system was trained using a three-stage curriculum with carefully curated datasets from public sources.

Stage 1: Foundation Reasoning

Atlas Reasoning Dataset

• Source: Custom generated
• Size: ~10,000 samples
• Format: Instruction-following with chain-of-thought
• Purpose: Establish baseline reasoning capabilities

{"instruction": "Solve this step by step", "input": "...", "output": "Let me think..."}

Stage 2: Math + Physical Sciences

OpenMath Dataset

• Source: OpenMath
• License: CC BY 4.0
• Samples Used: 10,000
• Topics: Algebra, Calculus, Number Theory, Geometry
• Selection: Filtered for graduate-level difficulty

GPQA (Physics + Chemistry)

• Source: GPQA Dataset
• License: CC BY 4.0
• Physics Samples: 3,000
• Chemistry Samples: 3,000
• Difficulty: Expert-validated, PhD-level

Stage 2 Composition:

total_samples: 16,000

• Expert Validation: Each question validated by domain experts
• Non-Expert Baseline: ~35% accuracy

Question Characteristics

• Average expert time: 20-30 minutes
• Expert accuracy: ~70%
• Non-expert accuracy: ~35%
• Web search allowed: still challenging

Sample Fields

{
  "Question": "...",
  "Correct Answer": "A",
  "Incorrect Answer 1": "B",
  "Incorrect Answer 2": "C",
  "Incorrect Answer 3": "D",
  "Explanation": "...",
  "Subdomain": "Molecular Biology",
  "Writer's Difficulty Estimate": "Hard graduate level",
  "Expert Validator Accuracy": 0.5,
  "Non-Expert Validator Accuracy": 0.0
}

Data Processing Pipeline

Pipeline Components

1. Text Cleaner: Normalize formatting, fix encoding
2. Quality Filter: Remove low-quality samples
3. Deduplicator: MinHash-based deduplication
4. Chain-of-Thought Processor: Enhance with reasoning steps
5. Tokenizer: Qwen tokenizer compatible

Quality Scoring

Each sample receives a quality score based on:

• Response completeness
• Reasoning chain validity
• Answer correctness
• Format compliance

Diversity Checking

Ensures balanced representation across:

• Difficulty levels
• Subject domains
• Question types
• Required reasoning depth

Reproducibility

To recreate the training data:

# Install dependencies
pip install datasets transformers

# Run dataset preparation
python grogu/scripts/prepare_all_datasets.py

# Validate datasets
python grogu/scripts/validate_datasets.py

# Analyze statistics
python grogu/scripts/analyze_dataset_stats.py

Dataset Statistics Script Output

Stage 2 Dataset:
  Total: 16,000 samples
  Mathematics: 62.5%
  Physics: 18.75%
  Chemistry: 18.75%

Stage 3 Dataset:
  Total: 8,000 samples
  Biology: 37.5%
  Biochemistry: 62.5%

Ethical Considerations

Data Quality

• All sources are publicly available
• Expert-validated questions
• No personal identifiable information
• Academic use focused

Bias Mitigation

• Balanced domain representation
• Multiple expert validators per question
• Diverse question writers

Limitations

• English-only
• Western academic focus
• May not cover all scientific domains equally
