AI0-001 AI Concepts and Foundations Practice Question
Exhibit
Refer to the exhibit. Epoch 1/50 - loss: 2.4503 - val_loss: 2.4512 Epoch 10/50 - loss: 1.2345 - val_loss: 1.3456 Epoch 20/50 - loss: 0.9876 - val_loss: 1.1234 Epoch 30/50 - loss: 0.6543 - val_loss: 0.9876 Epoch 40/50 - loss: 0.4321 - val_loss: 0.8765 Epoch 50/50 - loss: 0.3210 - val_loss: 0.8321
Based on the exhibit, what is the most likely issue with the model training?
⚠ Common exam trap
CompTIA often tests the distinction between overfitting and underfitting by showing a diverging validation loss curve, which candidates may misinterpret as a learning rate issue or vanishing gradient.
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
✓
Overfitting
The exhibit shows training loss decreasing while validation loss increases after a certain point, which is a classic sign of overfitting. The model is memorizing the training data rather than generalizing, leading to poor performance on unseen validation data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Vanishing gradient
Why it's wrong here
Vanishing gradient would cause training loss to plateau early, not the observed pattern.
- ✗
Learning rate too high
Why it's wrong here
A high learning rate would cause loss to oscillate or diverge rapidly, not a gradual decrease then increase in validation loss.
- ✗
Underfitting
Why it's wrong here
Underfitting would show high training and validation loss throughout, not the diverging pattern seen here.
- ✓
Overfitting
Why this is correct
The diverging validation loss after initial improvement indicates the model is memorizing the training data and failing to generalize.
