Undirected Graphical Models - Duke University
Undirected graphs Theorem 1 (Handshaking Theorem): If G= (VE) is an undirected graph with medges then 2 L Í deg : R ; ? Ï Proof: Each edge contributes twice to the degree count of all vertices Hence both the left-hand and ri ght-hand sides of this equation equal twice the number of edges

A undirected graphical model or Markov Net is a pair where is an undirected graph and is a set of factors corresponding to the cliques in Since we construct the graph to reflect the structure of the factors in graph separation implies independence and vice versa We will see that the undirected graph will be our workhorse for the
Lecture 14 - Stanford University
a certi cate that the graph is not bipartite Several optimization problems become simpler in bipartite graphs The problem of nding a maximum matching in a graph is solvable in polynomial time in general graphs but it has a very simple algorithm in bipartite graphs that we shall see shortly
1 Connected components in undirected graphs - Stanford University
Oct 19 2016 · 1 1 Algorithm to ?nd connected components in a undirected graph In order to ?nd a connected component of an undirected graph we can just pick a vertex and start doing a search (BFS or DFS) from that vertex All the vertices we can reach from that vertex compose a single connected component
What is an undirected graphical model?
A undirected graphical model, or Markov Net, is a pair , where is an undirected graph and is a set of factors corresponding to the cliques in . Since we construct the graph to reflect the structure of the factors in , graph separation implies independence and vice versa.
What is a connected component of an undirected graph?
A connected component of an undirected graph G= (V,E) is a maximal set of vertices S? V such that for each u? S and v? S, there exists a path in Gfrom vertex uto vertex v. De?nition 1.1 (Formal De?nition) Let u? vif and only if Ghas a path from vertex uto vertex v.
Can undirected graphs explain joint probability distributions?
Undirected Graphical Models Mark Alan Peot Read: Chapters 5 and 6 of [CGH]. 1.0 Goal The first model for a joint probability distribution that we will consider is the undirected graph. We will undirected graphs using two different methods. First, we will show the relation- ship between undirected graphs and joint probability distributions.
What is a biconnected graph?
Takes O (E (V + E)) and O (V (V + E)) time, respectively. Can improve both to O (E + V) using clever extension to DFS. Biconnected components. An undirected graph is biconnected if for every pair of vertices v and w, there are two vertex-disjoint paths between v and w. (Or equivalently a simple cycle through any two vertices.)
