Reinforcement Learning and Deep RL Python Theory and Projects - DNN Why Activation Function Is Required

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 importance of nonlinear functions in maintaining the representation power of multilayered networks. The video concludes with a brief mention of upcoming content on different types of activation functions.
