Deep Learning - Crash Course 2023 - Activation Function

The video tutorial explains the role of activation functions in neural networks, drawing parallels to the human brain's threshold response. It covers the process of building a neural network, using data to train it, and determining weights and biases. The tutorial uses an employee hiring example to illustrate these concepts, emphasizing the importance of data in machine learning. It concludes with an introduction to bias and its role in introducing nonlinearity to neural networks.
