Unofficial m-a-p/FineFineWeb Equal Weighted Sample

A balanced, class-weighted subset of m-a-p/FineFineWeb optimized for multi-class text classification tasks.

📊 Dataset Overview

To prevent class imbalance issues during model training, this dataset extracts an equal-weighted sample across all fine-grained domain classes.

• Original Dataset: m-a-p/FineFineWeb
• Total Samples: 134,000 (0 duplicates)
• Training Set (85%): 113,900 rows
• Validation Set (15%): 20,100 rows
• Classes: 67 balanced domains (2,000 samples per class)

🚀 Quick Start
