SMSS Colloquium Talk - Rick Jardine

Speaker: Rick Jardine

Title: Cluster graphs

Abstract:
Clusters appear in many guises in data analysis. Basically, they are what you think they are, namely groups of things in proximity that is determined by parameters that vary. The parameters are often distance or time, or both. The trick, in mathematical models, is to describe the meaning of proximity. This talk will describe the persistence approach to the description and analysis of clusters, with an approach that involves simple graphs.
