What is machine learning?
Computers that learn from examples and experience, instead of following instructions step by step. The big idea in plain words.
How a puppy learns: reinforcement learning
Trial, error and rewards. See how a computer can learn a maze with nobody telling it the way.
Be careful what you reward
Why AI does what you ask, not what you meant, and how a puppy found a loophole.
Activity guides
Hands-on activities for home, class or self-study.
Be the algorithm: train a puppy with paper and a friend
A no-computer activity where one person is the puppy and another is the trainer. Learn reinforcement learning by doing it.
Computers without computers: binary cards and logic gates
Unplugged activities for learning how computers work: count in binary with cards, draw pictures from numbers, and be a logic gate.
