AI0-001 Machine Learning and Deep Learning Practice Question
A machine learning engineer notices that the gradient values in a deep network are becoming extremely small during backpropagation. What is this problem?
⚠ Common exam trap
The AI0-001 exam often tests the distinction between vanishing and exploding gradients by describing the symptom (small vs. large gradients) and expects candidates to recognize that vanishing gradients cause slow learning in early layers, not just any training difficulty.
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
✓
Vanishing gradient
The vanishing gradient problem occurs when gradients become extremely small during backpropagation, especially in deep networks with many layers. This causes the weights in earlier layers to update very slowly or not at all, severely hindering training. The correct answer is D because the scenario directly describes the hallmark symptom of vanishing gradients.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dead ReLU
Why it's wrong here
Dead ReLU causes neurons to output zero regardless of input, not gradient size.
- ✗
Exploding gradient
Why it's wrong here
Exploding gradient causes large gradients, not small.
- ✗
Covariate shift
Why it's wrong here
Covariate shift refers to changes in the input distribution, not gradient magnitude.
- ✓
Vanishing gradient
Why this is correct
Correct: Vanishing gradient makes weights stop updating effectively.
