📌 Day 19: 21 Days of Building a Small Language Model: Residual Connections 📌

#ai #llm #gpt3 #programming

Welcome to Day 19 of 21 Days of Building a Small Language Model. The topic for today is residual connections, also known as shortcut connections or skip connections. Today, we'll discover how residual connections solve the vanishing gradient problem and enable training of very deep networks, making modern transformers possible

Residual connections let information flow directly across layers by adding the input of a layer back to its output. Instead of forcing every layer to learn everything from scratch, the model only learns the difference (the residual).
