What is the purpose of activation functions in neural networks?
Activation functions introduce non-linearity, allowing the network to learn complex patterns. Without them, the network would behave like a simple linear model, unable to capture non-linear relationships. Popular activation functions include ReLU, Sigmoid, and Tanh. Understanding these concepts is essential for anyone exploring deep learning or enrolling in the Best Artificial Intelligence Course Online, as activation functions form the foundation of how neural networks process information.
