SpeedLM-Dataset-TR: Cleaned Turkish Wikipedia for Minimalist LLMs

This dataset is a high-quality, pre-processed Turkish Wikipedia corpus specifically curated for training SpeedLM (Matmul-free, Hash-based Language Models) and other lightweight architectures.

📌 Dataset Summary

• Source: Turkish Wikipedia (Cleaned)
• Format: Line-separated raw UTF-8 text
• Preprocessing: Stripped JSONL metadata, normalized whitespaces, and preserved Turkish character integrity.
• Target Model: SpeedLM v0.1 (Byte-level Ternary Model)

🎯 Purpose

Traditional datasets are often cluttered with JSON structures and metadata. This dataset provides a pure text stream optimized for:

1. Byte-level Training: No complex tokenizers needed.
2. High-Speed Streaming: Optimized for single-pass online learning.
3. Hash-Based Contexts: Uniform text distribution to minimize hash collisions in sparse architectures.

🛠 Preprocessing Pipeline

The data was extracted from wiki_cleaned4.jsonl using a custom Python pipeline:

1. Extraction: Isolated the output field from each JSON line.
2. Sanitization: Removed null bytes and control characters that break byte-level models.
3. Normalization: Collapsed multiple spaces into a single space and ensured \n line-ending consistency.

📊 Data Statistics

Metric	Value
Language	Turkish (TR)
Encoding	UTF-8
Vocab Size	256 (Byte-level)
Structure	One Wikipedia paragraph per line
