Welcome to Natural Language Processing!
NLP is the branch of AI that enables computers to understand, interpret, and generate human language. Unlike programming languages with strict rules, human language is messy, context-dependent, and full of nuances.
Key Insight: NLP bridges the gap between human communication and computer understanding, making it possible to interact with machines using everyday language.
The ChatGPT Revolution & Modern AI
Large Language Models (LLMs) like ChatGPT, Claude, and Bard represent the current pinnacle of NLP technology, trained on vast amounts of internet text.
What Makes Them Different
• Scale: Billions of web pages
• Context: Coherent conversations
• Versatility: Creative + technical tasks
• Few-shot learning: Adapt quickly
Transformer Architecture
Unlike sequential processing, transformers analyze entire sentences simultaneously, understanding relationships between all words at once for better context
Limitations
• Hallucination: Confident but wrong info
• Bias: Reflects training data
• Privacy: Data storage concerns
• Reliability: Needs human oversight
