Topological Data Analysis Discussion Group

Those interested in Topological Data Analysis (TDA) at the University of Florida will have Discussion Group meetings. In these meetings, a paper in the area of TDA will be briefly presented and the remainder of the meeting will be dedicated to questions and discussions. The talks are not meant to go into the depth of a paper, rather the overview of the paper will be given with emphasis on the main ideas. The purpose of these meetings is to practice reading papers and giving talks. Interesting research projects could potentially arise as well. Anyone interested in TDA is welcome to attend. If interested in attending send an email to nikola@ufl.edu.
