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
