Professor Mike Wooldridge asks: what is artificial intelligence? He compares how AI works and learns with how the human brain functions. Exploring the roots of AI, Mike reveals how Alan Turing devised the Imitation Game – a test of whether a machine answering a series of questions could pass as a human. The audience in the lecture theatre play a real-life version of the game to find out if AI can pass this test today.
