Challenge Problems

Push your limits with challenges.

Question 1

Imagine a neural network with 3 layers including the input layer. If the network produces an output error of 0.5, explain how backpropagation would adjust the weights from the output back to the input layer.

πŸ’‘ Hint: Consider how the error affects each layer's weights individually.

Question 2

What challenges might arise during the backpropagation process in a very deep neural network, and what techniques can be used to address them?

πŸ’‘ Hint: Think about properties of activation functions and structural changes in the network.
