Inference Algorithms for Bayes Networks

Inference Algorithms for Bayes Networks. Outline. Bayes Nets are popular representations in AI, and researchers have developed many inference techniques for them. We will consider two types of algorithms: Exact inference (with 2 subtypes) Enumeration Variable elimination

Lecture 9 Randomized Algorithms

Lecture 9 Randomized Algorithms. Quicksort. Goal: Sort a list of numbers a[] = {4, 2, 8, 6, 3, 1, 7, 5} Algorithm: Pick a random pivot number (say 3) Partition the array into numbers smaller and larger than the pivot ({2, 1}, {4, 8, 6, 7, 5}) Recursively sort the two parts. Recursion.
