Diagnosing the Effects of Regularization on a Dev Set Error
Case context: A machine learning engineer notices that their neural network has a high variance error. To resolve this, they decide to add regularization, choosing between L2 regularization, L1 regularization, or dropout.
Question: Describe the impact this decision will have on both the variance and the bias of the neural network model.
Sample answer: Introducing regularization (L2 regularization, L1 regularization, or dropout) will successfully reduce the model's variance. However, the engineer must expect that this change will also increase the model's bias.
Key points:
- Adding regularization reduces variance.
- Adding regularization increases bias.
- The methods of regularization mentioned are L2 regularization, L1 regularization, and dropout.
Rubric: The student must identify that adding regularization (L2, L1, or dropout) reduces variance and increases bias.
