Which technology is a subset of AI that focuses on learning from data?

• A. AI
• B. ML
• C. Robotics
• D. NLP

Answer: (B)

Learning from data is the key idea behind machine learning, which is a part of artificial intelligence that builds models by analyzing data rather than following fixed, hand-coded rules. In practice, machine learning uses datasets to train algorithms, finds patterns, and then can predict or decide on new data it hasn’t seen before. This is how systems improve with experience.

Artificial intelligence is the broader field that includes many approaches, not just learning from data. Robotics, for example, focuses on physical intelligent agents and how they move and interact with the real world. NLP (natural language processing) concentrates on understanding and generating human language. Among these, machine learning is the specific technology that learns from data to perform tasks such as classifying emails, recognizing images, or predicting outcomes.
