spectral graph theory course

The course meets Tuesdays and Thursdays in Rhodes 571 from 10:10-11:25AM. Please take a minute to review the course policies. Overview . Welcome to Spectral Graph Theory. Centre for International ProgramsAmritapuri, Corporate & Industry RelationsAmritapuri | Bengaluru | Coimbatore | Kochi | Mysuru. At a very high level the course shows how one can use linear algebra to solve fundamental problems in computer science much more efficiently. This course will consider the interplay between continuous and discrete optimization broadly speaking, but with a focus on algorithmic spectral graph theory and applications of the multiplicative weights update paradigm.

On the other hand, most of our examples are … This text is an introduction to spectral graph theory, but it could also be seen as an invitation to algebraic graph theory. I will post all the homework assignments for the course on this page. M.E.J. If x= a+ibis a complex number, then we let x= a ibdenote its conjugate. Instructor: Dan Spielman. On the one hand, there is, of course, the linear algebra that underlies the spectral ideas in graph theory. Yale College juniors and seniors are also welcome.

In this case, we should Please take a minute to review the course policies. This course will consider connections between the eigenvalues and eigenvectors of graphs and classical questions in graph theory such as cliques, colorings, cuts, flows, paths, and walks. However, I stress that this is an advanced course of mathematical nature, and so mathematical maturity is essential to follow the course successfully. Ben-Aroya - Ta-Shma paper on the wide replacement product, Alon-Goldreich-Hastad-Peralta's construction of small-bias sets, Ta-Shma's construction of near-optimal small-bias sets. In the following, we use G = (V;E) to represent an undirected n-vertex graph with no self-loops, and write V = f1;:::;ng, with the degree of vertex idenoted d i. The recitation, by Shir, is in the following hour. it cannot be deformed without loosing symmetry), and irreducible, then one can show that it satisfies $(*)$ (it is not necessarily spectral, but almost).

The book for the course is on this webpage. To connect this to spectral graph theory, one can observe that if a realization is rigid (i.e. CPSC 462/562 is the latest incarnation of my course course on Spectral Graph Theory. Access.

A two-part video talk by Amnon Ta-Shma on his small-bias sets construction (, Daniel Spielman's book (incomplete; available online), Several video talks from Simons Berkeley on SGT, Salil Vadhan chapter on expander graphs from his Pseudorandomness monograph. I suggest you'll watch Spielman's talk Miracles of Algebraic Graph Theory to get a sense of what this course is mostly about. This course is about applications of linear algebra to graph theory and to graph algorithms. Today, we Experience working with complex network data sets and implement computer algorithms to solve network problems, use modern network tools to analyze data, Compare different solutions of large network problems in terms of network performance measures, Compare structure of different types of networks. We will not follow any particular text but below are resources which we will use. Welcome to the homepage for Graph Theory (Math/CSCI 4690/6690)! You can find the schedule of lectures and assignments, here. Measures and metrics- Degree centrality, Eigenvector centrality, Katz centrality, PageRank, Hubs and authorities, Closeness centrality, Betweenness centrality, Transitivity, Reciprocity, Similarity, assortative mixing. The interconnections between properties of graphs and the eigenvalues of some matrices associated with graphs are studied. Dougles West, “Introduction to Graph Theory”, Second Edition, PHI Learning Private Limited, 2011. Salil Vadhan chapter on expander graphs from his Pseudorandomness monograph. We invite you to a fascinating journey into Graph Theory — an area which connects the elegance of painting and the rigor of mathematics; is simple, but not unsophisticated. In this course we will cover the basics of the field as well as applications to theoretical computer science. It will also be broadcast to Cornell NYC Tech, Ursa room. Then, we will cover recent progress on graph sparsification, Kadison-Singer problem and approximation algorithms for traveling salesman problems. Explicit constructions of expander graphs, Unit 12. Course : Data mining Lecture : Spectral graph analysis Aristides Gionis Department of Computer Science Aalto University visiting in Sapienza University of Rome fall 2016. spectral graph theory. Spectral graph theory is the powerful and beautiful theory that arises from the following question: ... Of course, if the graph has a single connected component, the smallest eigenvector v 1 = (1= p n;:::;1= p n), which is not helpful for embedding, as all points have the same value. We will start by reviewing classic results relating graph expansion and spectra, random walks, random spanning trees, and their electrical network representation. Alain Barrat, Marc Barthelemy and Alessandro Vespignani, “Dynamical processes on Complex networks”, Cambridge University Press, 2008. Time: M-W 2:30-3:45. Describe fundamental tools to study networks, mathematical models of network structure, computer algorithms for network data analysis and the theories of processes taking place on networks. Spectral theory of real symmetric matrices, Unit 3. This is a research-oriented graduate course in spectral graph theory. Spectral graph theory studies how the eigenvalues of the adjacency matrix of a graph, which are purely algebraic quantities, relate to combinatorial properties of the graph. Algebraic graph theory by Godsil and Royle. In the summer of 2006, the daunting task of revision finally but surely got started. weighted digraph), which is a more general type of graph than the type de ned in Chapter 1 of Spielman’s book. Spectral graph theory-- a book focused on the definition and development of the normalized Laplacian written by Fan Chung, the first four chapters of the revised version are available online. All but for the Godsil-Royle book are available, for free, online. While the adjacency matrix depends on the vertex labeling, its spectrum is a graph invariant, Unit 2. Course projects. Lecture 11: Introduction to Spectral Graph Theory Rajat Mittal IIT Kanpur We will start spectral graph theory from these lecture notes. The adjacency matrix of a simple graph is a real symmetric matrix and is therefore orthogonally diagonalizable; its eigenvalues are real algebraic integers. Newman, “Networks: An Introduction”, Oxford University Press, 2010. in Computer Science & Engineering, Statistical and Probabilistic Modeling in Civil Engineering. Overview . Graph Theory gives us, both an easy way to pictorially represent many major mathematical results, and insights into the deep theories behind them. Some background in discrete probability and graph theory is helpful, but the course is self-contained. Let the course sta know if you need help nding other students in the class willing to discuss the course material or collaborate on Problem Set 0. Ta-Shma's explicit construction of codes close to the Gilbert-Varshamov bound. The main course work is the course project. At a very high level the course shows how one can use linear algebra to solve fundamental problems in computer science much more efficiently. Welcome to Spectral Graph Theory. These are lecture notes that are based on the lectures from a class I taught on the topic of Spectral Graph Methods at UC Berkeley during the Spring 2015 semester. Course: Spectral Graph Theory from Yale. This course is open to students from Statistics and Computer Science as well. 'Networks and Spectral Graph Theory' is an elective course offered in M. Tech. Submissions are in pairs. You won't need a copy of the latter, so no worries. . This is a research-oriented graduate course. 3 Graphs In this course, the word \graph" will refer to a weighted directed graph (a.k.a.
