Large Language Models (LLMs) are advanced AI models trained on massive datasets to understand and generate human-like text. They power applications like chatbots, search engines, content generation, and more. This repository serves as a comprehensive study guide to understand the fundamentals, inner workings, applications, challenges, and future of LLMs.
- ✅ Transformative Technology: Powering search, chatbots, code generation, and creative AI.
- ✅ Cutting-Edge Research: Constant advancements in NLP and AI ethics.
- ✅ High-Demand Skills: Essential knowledge for AI, ML, and NLP engineers.
- ✅ Real-World Impact: Used in finance, healthcare, education, and beyond.
- Pretraining: Model learns general language patterns from vast amounts of text.
- Fine-Tuning: Adapts to specific tasks like translation, question answering, or summarization.
- Prompt Engineering: Optimizing inputs to guide the model's responses effectively.
- Transformer Architecture (Self-Attention, Multi-Head Attention)
- Tokenization (Byte Pair Encoding, WordPiece)
- Fine-Tuning & Adaptation (Instruction Tuning, RLHF)
- Embedding Representations (Word2Vec, BERT, GPT-based models)
- Tokenizer: Breaks text into tokens for model input.
- Embedding Layer: Converts tokens into numerical representations.
- Transformer Blocks: Processes text using self-attention mechanisms.
- Decoding & Output: Generates human-like text based on learned patterns.
