Seriguela - Symbolic Regression with Large Language Models

A research project exploring the application of GPT-2 models to symbolic
regression through fine-tuning and reinforcement learning.

Model Scaling Study Results:
- Base (124M): 99.4% valid rate, R² = 0.9190
- Medium (355M): 99.2% valid rate, R² = 0.9812
- Large (774M): 100% valid rate, R² = 0.9852, Perfect R²=1.0 achieved

Key Features:
- LoRA fine-tuning (only 294K trainable parameters)
- JSON structured format (80% valid expressions)
- Reinforcement learning algorithms (PPO, GRPO, REINFORCE)
- Comprehensive evaluation on Nguyen benchmarks
- Publication-ready results and visualizations

Usage:
    from classes import Expression, Dataset
    from configs import generate_run_name, get_wandb_project_name

Research Status:
    ✅ Complete model scaling study
    ✅ 5,100 evaluations (1,500 quality + 3,600 Nguyen)
    ✅ Publication-ready (12-page scientific report)
    ✅ State-of-the-art results (100% valid, R²=1.0)
