Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a neural network training on a binary classification task. Discuss how the choice of activation function for the output layer influences the network's performance and predictions.

💡 Hint: Think about how the output should express probabilities.

Challenge 2 Hard

Explain how using ReLU instead of Sigmoid in hidden layers impacts learning speed and convergence during training.

💡 Hint: Consider the gradient behaviors of both functions.
