: Clean the raw data by removing HTML, handling special characters, and deduplicating content to prevent the model from simply memorizing repeated text. Tokenization
They also found that by incorporating a novel attention mechanism, they could enhance the model's ability to capture long-range dependencies and contextual relationships. build a large language model from scratch pdf
