Learning Goals
- Naive Bayesian networks
- Bayesian networks
- Decision networks
- Students can define a multivariate joint distribution: multinomial and Gaussian
- Students can explain the difference between association versus causation
- Students can define observational, causal, and counterfactual inference
- Students can define fairness using observational and counterfactual reasoning
Expected Preparation

Instructions for Teachers
- Reminder: framework of a one-step decision problem, elements (action, uncertainty, utility/loss), maximum expected utility principle
- Reminder: probabilistic graphical models, causal diagrams
- Define elements of a decision network: chance, action, utility/ loss nodes
- Explain workflow: evidences, actions, probabilistic inference, expectations, maximizing action
- Example
- Discuss value of information
