Wenrui Hao - Department of Mathematics, Pennsylvania State University
Nov 25, 2019 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Siegal Hall, Room 118
In this talk, I will start a recent mathematical model that predicts the plaque formation by using the combined levels of (LDL, HDL) in the blood. The model is described by a system of partial differential equations with a free boundary. Then some numerical methods will be discussed to solve the... read more

Department of Applied Mathematics - Seminar - RE 119
We investigate dimensionality reduction for Euclidean \(k\)-means and \(k\)-medians clustering. We show that the cost of the optimal solution for \(k\)-means and \(k\)-medians is preserved up to a factor of  \( (1+\varepsilon) \) under a projection onto a random  \( \log k\)dimensional... read more

Mladen Kolar - Booth School of Business, University of Chicago
Nov 18, 2019 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Siegal Hall, Room 118
We present a recent line of work on estimating differential networksand conducting statistical inference about parameters in ahigh-dimensional setting. First, we consider a Gaussian setting andshow how to directly learn the difference between the graphstructures. A debiasing procedure will be... read more
