How Large Language Models Actually Work: From Text Processing to Intelligent Generation
2 days ago 高效码农Large Language Model Architecture Since the emergence of ChatGPT, large language models (LLMs) like GPT-4 and Claude have revolutionized how machines understand human language. This article demystifies the technical principles behind these AI systems, explaining their capabilities and limitations in plain language. 1. Text Preprocessing: Converting Chaos into Machine-Readable Data 1.1 Text Normalization: Standardizing Human Language Lowercasing: Treats “ChatGPT” and “chatgpt” as identical Unicode Normalization: Resolves encoding variations (e.g., “café” vs. “café”) Colloquial Conversion: Transforms informal expressions like “gonna” to “going to” Typical Workflow: Raw Text → Lowercase Conversion → Unicode Normalization → Special Character Filtering → Clean Text 1.2 Subword Tokenization: Solving the Vocabulary Explosion Problem Modern LLMs use Byte Pair Encoding (BPE) …
