when A hypothesis h is called consistent

• if h(x) = c(x)²

• if h(x) = 2c(x)

• if h(x) = c(x)

• none of these

A computer program is said to learn from experience E with respect to some task T and some performance measure P if its performance on T, as measured by P, improves with experience E. Suppose we feed a learning algorithm a lot of historical weather data, and have it learn to predict weather. In this setting, what is T?

• The process of the algorithm examining a large amount of historical weather data.

• The weather prediction task.

• None of these.

• The probability of it correctly predicting a future date's weather.

Which of these is a reasonable definition of machine learning?

• Machine learning is the field of allowing robots to act intelligently.

• Machine learning learns from labeled data.

• Machine learning is the science of programming computers.

• Machine learning is the field of study that gives computers the ability to learn without being explicitly programmed.
