Joint Algebra and Statistics Seminar

Moduli of Tropical Plane Curves 
 
Smooth curves in the tropical plane come from unimodular triangulations of lattice polygons. The skeleton of such a curve is a metric graph whose genus is the number of lattice points in the interior of the polygon. In this talk we report on work concerning the following realizability problem: Characterize all metric graphs that admit a planar representation as a smooth tropical curve. For instance, about 29.5 percent of metric graphs of genus 3 have this property. (Joint work with Sarah Brodsky, Michael Joswig, and Bernd Sturmfels.)

Applied Math Seminar

Topic: Text as Data

Abstract: Professor Wedeking will give a summary of three projects that he has been involved in using text as data (1 is published, 1 is under review, and 1 is ongoing). Specifically, for each of the 3 projects, He will:  (1) describe the method he's using, what it generally is used for;  (2) the motivation for the project-e.g., the substantive research question and relevant background information;  (3) a brief description of the data; and  (4) the results of the method and the substantive conclusions.  The three projects are: (1) measuring how legal issues are framed (e.g., free speech vs. right to privacy, etc) and how that helps parties win; (2) uncovering the clarity of texts using readability formulas; and (3) scaling justices with texts- uncovering their ideological positions (how liberal or conservative they are) using their words.
