On Thursday Jan. 18, Sami Abu-El-Haija, UofT Alumni and currently at Google Research, will be at UofT to share a talk on Machine Learning on Graphs, hosted by the Department of Electrical & Computer Engineering.
Join Sami as he summarizes the field, sharing insights about some of Google's work in this area. You will learn about representing graphs in a continuous vector space, graph convolution, random walks, and how these techniques can be used for unsupervised and semi-supervised learning.
Please RSVP here
This talk is well suited to gradate students in ECE, CS, Math, etc. Students who might not be familiar with Machine Learning or Representation Learning are encouraged to join, as Sami will provide a review of the field.
Abstract: Graph-structured data is prevalent across many domains, including social networks, biological networks, and e-commerce. In these settings, one might wish to infer information missing from the graph, for example, predict user interests in a social network or predict if two proteins interact in a biological network. However, modern Machine Learning techniques, such as Deep Learning, usually operate on continuous-valued inputs (e.g. floating-point numbers) while graphs are naturally described in discrete form (e.g. nodes and edges). In this talk, the speaker will describe modern embedding techniques that project graphs onto a continuous vector space. In addition, he will describe graph convolution and how it can be used for semi-supervised node classification, where the labels are observed for only a fraction of the nodes and one wishes to recover all unobserved labels. You will hear about some of Google's work in these domains, which include learning an edge function, and combining random walks with graph convolution for semi-supervised learning. Students who might not be familiar with Machine Learning or Representation Learning are encouraged to join, as he will do a review of the field.
