Understanding and Coding Self-Attention, Multi-Head Attention, Causal Attention, and Cross-Attention in LLMs

This article provides a comprehensive guide to understanding and implementing self-attention mechanisms used in transformer architectures and large language models (LLMs) like GPT-4 and Llama. It covers self-attention, multi-head attention, causal attention, and cross-attention through hands-on coding in Python and PyTorch from scratch. The tutorial assumes basic knowledge of LLMs and attention mechanisms, focusing on technical implementation to deepen understanding of these core components in modern NLP models.
