What is machine learning?

• A. A system that follows fixed rules regardless of data
• B. A system that cannot improve with more data
• C. A system that relies on explicit programming and hand-tuned instructions
• D. A system trained to analyze data and recognize patterns

Answer: (D)

Machine learning is a system that analyzes data to find patterns and make predictions. Instead of following fixed, hand-written rules, it learns from examples—building a model that captures relationships in the data. As more data becomes available, the model can be retrained to improve its accuracy and adapt to new situations. This ability to learn from data and recognize patterns is what sets machine learning apart from traditional programming, where instructions are explicitly coded and do not automatically improve with more information. So the best description is a system trained to analyze data and recognize patterns.
