With advanced in computer and sensor technologies, large-scale data sets are now routinely generated and recorded from a wide range of sources in business, sciences, engineering, health care and medical research, etc. Although data-driven method...

In many fields such as medicine, engineering, economics and psychology, we often encounter a pooled population and its observations while the subpopulation identification is of interest but unobserved. For example, primary care physicians want to...

I shall first explain the concept of sparse solution of rectangular linear system. Algorithms such as L1 minimization and greedy strategy will be introduced for finding a sparse solution of underdetermined linear system. As an example, economic...

Chronic disease management often involves sequential decisions that have long-term implications. Those decisions are based on high dimensional information, which pose a problem for traditional modeling paradigms. In some key instances, the disease...

The American Statistical Association (ASA) DataFest is a celebration of data in which teams of undergraduates work around the clock to find and share meaning in a large, rich, and complex data set. From March 29–31, undergraduate students from...

Stratified shear flows are ubiquitous features of the ocean and atmosphere, and a large literature is devoted to describing their stability and mixing properties. A classical results is the Miles-Howard theorem, which states that a necessary...

Please join us at the Annual Meeting of the Canadian Society for the History and Philosophy of Mathematics for three days of presentations on a variety of topics in history and philosophy of mathematics from Sunday 29 May to Tuesday 31 May. A special...

Entropy is one of the most important invariants in dynamical systems, in both measure-theoretic and topological settings. The original Kolmogorov-Sinai entropy was introduced for integer group actions in the late 1950s and extended to amenable group...

In this talk, I will present my recent result about the ergodic properties of nonequilibrium steady-state (NESS) for a stochastic energy exchange model. The energy exchange model can be seen as a stochastic approximation of a certain billiards-like...

We establish rates of convergence of solutions to scaling (or similarity) profiles in a coagulation type system modelling submonolayer deposition. We prove that, although all memory of the initial condition is lost in the similarity limit...
