Probabilistic reasoning<br />

• Syntax and Semantics<br />

• Parameterized distributions<br />

• Bayes nets provide a natural representation<br />

for (causally induced) conditional<br />

independence<br />

• Topology + CPTs = compact representation<br />

of joint distribution<br />

• Canonical distributions (e.g., noisy-OR) =<br />

compact representation of CPTs<br />

• Continuous variables ) parameterized<br />

distributions (e.g., linear Gaussian)<br />
