Choose AnswerChoose the Best Answer

A

A model that learns very slowly, causing it to overfit the training data due to prolonged exposure.

B

A model that rapidly adjusts its weights but becomes unstable, leading to erratic performance and potential overfitting.

C

A model that maintains a consistent learning rate across all layers, ensuring stability and reducing the risk of overfitting.

D

A model that uses dropout effectively, reducing overfitting and improving training stability despite gradient issues.

Understanding the Answer

Let's break down why this is correct

When gradients explode, the numbers that guide weight updates become huge. Other options are incorrect because Slow learning is not caused by exploding gradients; Keeping a constant learning rate does not fix exploding gradients.
