Introduction to AI
- This lesson is specifically about machine learning.
- Introduction:
- Class discussion: Think-pair-share – what is artificial intelligence? Where have you seen it?
- Inspiring with examples
- Explain the story of the OpenAI Rubik’s cube solver, with the video playing in the background: https://www.youtube.com/watch?v=x4O8pojMF0w
- It’s not just amazing that it can solve Rubik’s cubes – computers could do that since just after the cube was released.
- It’s not just amazing that it can solve it with a robotic hand – we’ve been using robotic machines since Unimate’s robotic arm in 1961!
- What is amazing is that the computer could learn how to solve it in a simulated world, without ever seeing the real world. And when we put it in the real world, it could figure it out!
- Hence, the incredible thing with machine learning is that it can learn to do things for itself, without being told how to do them.
- Class discussion:
- We can see the process of learning in Google’s “Agent57”, where it trains a computer program to outperform humans at 57 different Atari games

- Again, it’s not impressive that computers can beat humans. Pong was made in 1972, and included an artificial intelligence enemy that could always beat the player.
- What is impressive is that the algorithm can only “see” the individual pixels. It must learn what the up button does, what the down button does, how the ball moves – everything.
- Although this is also very exciting, we can finish the lesson by a class discussion about ethics.
- Case study: COMPAS (Correctional Offender Management Profiling for Alternative Sanctions )
- Discuss this story on Machine Bias: https://www.propublica.org/article/machine-bias-risk-assessments-in-criminal-sentencing
- Students to prepare a debate:
- Should artificial intelligence be used in criminal sentencing?
