What is machine learning?

The correct option is The use of algorithms that improve automatically through experience.

Machine learning is a subset of artificial intelligence that focuses on developing algorithms that allow computer systems to learn from data and improve their performance on a specific task over time, without being explicitly programmed for every possible scenario. This learning process is driven by "experience" in the form of data.

The final answer is $\boxed{\text{The use of algorithms that improve automatically through experience}}$
