Challenge Problems
Push your limits with challenges.
Question 1
You have a neural network model that is consistently underperforming on validation data despite achieving a high accuracy on training data. Discuss how you could use backpropagation to improve the model. What strategies might you implement to combat overfitting?
💡 Hint: Think about how overfitting manifests and consider structural changes to the model.
Question 2
Consider a scenario where your learning rate is set too high. Describe the consequences and how you can identify that it's impacting the training of your neural network negatively.
💡 Hint: Reflect on how learning rates affect gradual adjustments of weights.
