INF2D: 22: Probabilities and Bayes' Rule
This folder provides a basic introduction to probabilistic inference. It consists of
- three videos of short lectures. They cover:
- Joint Probability Distributions
- Independence and Bayes' Rule
- Combining Evidence
- Some required reading from Russell and Norvig
- A quiz that tests your understanding of the material presented here.
Please watch the videos or attend the in-persion lecture, do the required reading, and attempt the quiz. If there is anything you don't understand, then please ask your question at the lecture or post it on piazza.
