AI0-001 AI Concepts and Techniques Practice Question
A startup wants to identify unusual patterns in network traffic to detect potential security breaches. They have a large dataset of normal traffic but very few labeled attacks. Which machine learning approach is MOST suitable?
⚠ Common exam trap
The AI0-001 exam often tests the misconception that semi-supervised learning is the best choice when labeled data is scarce, but the key distinction is that semi-supervised learning still requires a meaningful amount of labeled data for the target class, whereas unsupervised anomaly detection works with zero labeled attacks.
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
✓
Unsupervised anomaly detection
Unsupervised anomaly detection is the most suitable approach because the startup has a large dataset of normal traffic but very few labeled attacks. This technique learns the baseline of normal behavior from unlabeled data and flags deviations as potential anomalies, which is ideal for detecting unknown or rare attack patterns without requiring labeled attack samples.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Supervised classification with logistic regression
Why it's wrong here
Supervised classification requires many labeled attack examples, which are not available.
- ✓
Unsupervised anomaly detection
Why this is correct
Unsupervised anomaly detection can find deviations from normal traffic without needing labeled attack data.
- ✗
Reinforcement learning
Why it's wrong here
Reinforcement learning is for sequential decision-making, not for detecting anomalies in static data.
- ✗
Semi-supervised learning
Why it's wrong here
Semi-supervised learning still requires some labeled data; here very few labels exist.
