AI0-001 Machine Learning and Deep Learning Practice Question
A machine learning engineer is tuning a neural network for image classification. The training loss decreases steadily, but the validation loss starts increasing after 50 epochs. Which action best addresses this issue?
⚠ Common exam trap
The AI0-001 exam often tests the distinction between underfitting and overfitting symptoms, and the trap here is that candidates may confuse a rising validation loss with a need for more data or a deeper network, when the correct action is to stop training early to combat overfitting.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply early stopping with a patience of 10 epochs
The described behavior—decreasing training loss with increasing validation loss—is a classic sign of overfitting. Early stopping with a patience of 10 epochs directly addresses this by halting training when the validation loss fails to improve for a specified number of epochs, preventing further overfitting while retaining the best model weights.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the number of hidden layers
Why it's wrong here
Adding more layers increases model complexity and may worsen overfitting.
- ✗
Add more training data
Why it's wrong here
More data helps generalization but is often not immediately practical; early stopping is a more direct remedy.
- ✓
Apply early stopping with a patience of 10 epochs
Why this is correct
Early stopping monitors validation loss and stops training when it starts increasing, directly addressing overfitting.
- ✗
Increase the batch size
Why it's wrong here
Larger batch sizes can lead to sharper minima and may not prevent overfitting.
