Key Sequence Notation New Concepts multi-variant Gaussian density Generative Learning Algorithm Important Results / Claims applying Bayes rule to make prediction makes the sigmoid function Generative and Discriminate Algorithm Discriminative Algorithm Learns \(p\qty(y|x)\), or better yet just \(h\qty(x) \in \qty {0,1}\).
&ldquo;what&rsquo;s the distribution over labels&rdquo;
Generative Algorithm Learns \(p\qty(x|y)\) as well as a &ldquo;class prior&rdquo; \(p\qty(y)\). To make classification decisions, you apply Bayes rule. THINK: Naive Bayes.
