🚫 Applying a Causal Attention Mask – Live Coding with Sebastian Raschka (Chapter 3.5.1)

Check out Sebastian Raschka's book 📖 Build a Large Language Model (From Scratch) | https://hubs.la/Q03l0mSf0 📖 In this practical coding session, acclaimed ML author ‪@SebastianRaschka‬ demonstrates how to implement a causal attention mask — a vital component in autoregressive transformer models. Covering Chapter 3.5.1 of his book Build a Large Language Model (From Scratch), this video shows how to ensure that a token only attends to itself and earlier tokens during training. 0:00 - Introduction 0:58 - Causal Attention Mask Explained 3:01 - Implementing a Causal Self-Attention Class 7:16 - Simplifying Mask Application 11:11 - Preview of Upcoming Content 📘 About the Book Build a Large Language Model (From Scratch) is a practical and eminently-satisfying hands-on journey into the foundations of generative AI. Without relying on any existing LLM libraries, you’ll code a base model, evolve it into a text classifier, and ultimately create a chatbot that can follow your conversational instructions. And you’ll really understand it because you built it yourself! 💡 Ideal for ML engineers, NLP researchers, and developers building generative language models. 🔗 Get the Book: https://hubs.la/Q03l0mSf0 📺 Subscribe for expert-led walkthroughs, transformer tutorials, and live-coding sessions. #SebastianRaschka #LLM #CausalMasking #AttentionMask #Transformers #DeepLearning #NLP #ManningPublications #LiveCoding
