Natural Language Processing

Natural Language Processing (NLP) is a discipline in computer science and artificial intelligence that aims for computers to understand, interpret, and generate human language.

Fundamental Concepts

• Tokenization: The process of breaking text into meaningful units
• Word Embedding: Vector representations of words
• Language Models: Probabilistic modeling of text sequences
• Transformer Architecture: Attention mechanism-based deep learning models

Modern Approaches

• Large Language Models like GPT, BERT, T5
• Reinforcement Learning from Human Feedback (RLHF)
• Instruction Tuning

Application Areas

• Text classification and sentiment analysis
• Machine translation and summarization
• Question-answering systems and chatbots
• Named Entity Recognition (NER)

Recent advances in NLP have accelerated the integration of Large Language Models (LLMs) into daily life.
