Question

Which of the following is a type of machine learning?

• A. Structured learning
• B. Unsupervised learning
• C. Compiled learning
• D. Pattern learning

Hint:

Unsupervised learning helps find patterns in unlabeled data — like grouping similar customers or products.

Answer 1

The Correct Option is B

Step 1: Understanding types of machine learning
Machine Learning is broadly classified into:
Supervised learning: Trained with labeled data.
Unsupervised learning: Uses unlabeled data to find patterns or clusters.
Reinforcement learning: Learns through rewards and penalties.

Step 2: Option analysis

(1) Structured learning — Not a standard category.
(2) Unsupervised learning — Correct. It's a core branch of ML.
(3) Compiled learning — Not a valid ML category.
(4) Pattern learning — Refers to a concept but not a recognized type of ML.

Step 3: Conclusion
The correct and recognized category among the options is (2) Unsupervised learning.
