Data Science and Machine Learning (Theory and Projects) A to Z - DNN and Deep Learning Basics: DNN Why Activation Functi

The video explains the concept of activation functions in deep neural networks, emphasizing their role in preventing the collapse of the network into a single neuron. It highlights the necessity of nonlinear functions to maintain the representation power of multi-layered networks. The video also touches on the associative property of matrix multiplication and how it affects network layers. Finally, it sets the stage for further exploration of different types of activation functions and their implementation in Python.

What is the role of an activation function in deep neural networks?

What is meant by the term 'associative' in the context of matrix multiplication?

Explain the consequences of not using an activation function in a neural network.

Why is it important for activation functions to be nonlinear?

Describe the characteristics of a good activation function.
