Lesson Overview

1.10 – Activation Functions: The Brain Signals of AI: Activation functions determine how artificial neurons respond to input signals, enabling networks to learn non-linear relationships. They decide whether information should continue forward or be filtered out, mirroring how biological neurons fire. Common types include ReLU, sigmoid, and tanh, each influencing performance differently. Without activation functions, neural networks would behave like simple calculators unable to capture complexity. They allow AI systems to adapt, interpret emotions, recognize objects, and predict trends. Understanding activation functions reveals how digital brains make decisions, turning mathematical equations into simulated thought processes.
