SUMMARY:Ant-cog Seminar
DESCRIPTION:The ANT-CoG (Algebra\, Number theory\, Topology\, Combinatorics\, & Geometry) seminar will meet Friday\, 2/28\, from 4:00-5:00pm in Petty 150. We are pleased to welcome our own Dr. Thomas Weighill for Friday’s talk. \n\n\n\nTitle:  {vectorize\, data?\, unordered\, (continued)\, Can\, you} \n\n\n\nAbstract: In this talk we will continue to examine the question of whether vectorizations which introduce a bounded amount of distortion (i.e. coarse embeddings) exist for certain data types. It turns out that this question is also important in other fields such as geometric group theory and the topology of manifolds. I will touch on some known results about the space of probability distributions and the space of persistence diagrams. I will then present a recent result of my own on spaces of finite samples\, and quotients of spaces by finite group actions. This talk will be a thematic continuation of the previous one\, though it should be understandable even if you missed the first talk.

SUMMARY:ANT-CoG Seminar Talk
DESCRIPTION:The ANT-CoG (Algebra\, Number theory\, Topology\, Combinatorics\, & Geometry) seminar will meet Friday\, 2/21\, from 4:00-5:00pm in Petty 150. We are pleased to welcome our own Dr. Thomas Weighill for Friday’s talk. \n\n\n\nTitle:  {vectorize\, data?\, unordered\, Can\, you} \n\n\n\nAbstract: We will look at some very theoretical results motivated by the practical problem of visualizing and vectorizing complex datasets like shapes\, samples\, densities\, and even Congressional district maps. We will talk about some general strategies that sometimes work\, and prove at least one impossibility result showing that in some cases no good vectorizations exist. This talk will be designed to be accessible to undergraduate and graduate students.
