What is Machine Learning?

• A. Manual data entry
• B. A data visualization technique
• C. Artificial Intelligence that replicates how the human brain works
• D. A distributed ledger

Answer: (C)

Machine learning is a form of artificial intelligence where computer systems learn from data and improve their performance over time without being explicitly programmed. It uses algorithms that detect patterns in data, adjust as more examples are seen, and generalize what’s learned to new situations. This learning process is often described as AI that replicates how the human brain works, since neural networks are inspired by brain connections and can become more capable as they process more data. The other options don’t fit because manual data entry is just humans inputting data, not learning; a data visualization technique focuses on presenting data rather than learning from it; a distributed ledger records transactions, not learning from data. So machine learning is AI that learns from data to improve automatically.
