In the era of ChatGPT and Claude, Large Language Models (LLMs) often feel like magic black boxes. But behind the conversational fluency lies a stack of rigorous engineering and mathematical concepts.
- Deduplicate: Remove repeated text to prevent the model from memorizing specific passages.
- Filter: Remove toxic content, non-text symbols, and low-quality writing.
- Context Window: Chunk the data into fixed lengths (e.g., 512, 2048, or 8192 tokens) that fit into the model's memory.
