Deep Learning CNN Convolutional Neural Networks with Python - Activation Function

The video discusses the importance of activation functions in neural networks, focusing on their role in enabling nonlinearity and enhancing the network's decision-making capabilities. It covers various types of activation functions, including sigmoid and Relu, and explains their properties and applications. The video emphasizes the necessity of nonlinear functions to prevent the network from collapsing into a simple linear regression model. It concludes with a brief mention of the next topic, the training module.
