AI0-001 AI Concepts and Foundations Practice Question
A marketing team uses a recommendation system to suggest products to customers. The system currently uses collaborative filtering. Which scenario would most likely cause the cold-start problem?
⚠ Common exam trap
CompTIA often tests the cold-start problem by making candidates confuse it with performance issues or UI changes, but the trap here is that the cold-start problem is specifically about insufficient interaction data for new users or items, not about algorithm switches or interface redesigns.
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
✓
A new product is added to the catalog with no purchase history.
The cold-start problem occurs when a recommendation system lacks sufficient data to make accurate predictions. In collaborative filtering, recommendations rely on historical user-item interactions (e.g., purchase history). A new product with no purchase history has no interaction data, so the system cannot find similar users or items to generate recommendations, directly causing the cold-start problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A new product is added to the catalog with no purchase history.
Why this is correct
No interaction data exists for the new product, so collaborative filtering fails.
- ✗
The system switches from collaborative filtering to content-based filtering.
Why it's wrong here
Switching algorithm may have other issues but cold start is inherent to CF.
- ✗
The website interface is redesigned, affecting user navigation.
Why it's wrong here
Interface changes may affect user behavior but do not directly cause cold start.
- ✗
A seasonal product experiences a sudden spike in sales.
Why it's wrong here
Sales data exists; cold start refers to lack of data, not spikes.
