In the last of his Christmas Lectures, Chris Bishop looks at one of the great frontiers of computer science, Artificial Intelligence.

Find out how some of the toughest computational problems are now being tackled. Giving computers the ability to learn solutions for themselves, in much the same way as people learn by example, has led to impressive progress with problems such as recognising handwriting and finding information on the web.

However, Chris reveals how we are only beginning to explore the power of computation and the many challenges ahead in our quest for the ultimate computer.
