Question 1
A tech company has a complex neural network that shows excellent performance in training but drops in accuracy on a validation set. How would you advise them to approach this?
💡 Hint: Think about ways to reduce complexity without losing significant predictive power.
Question 2
During a practical session, a student builds a decision tree with a small dataset and achieves a high accuracy on training data but fails in validation. What mitigating strategies could they employ?
💡 Hint: Consider methods that ensure the model isn't too specifically tuned to the training data.
