What is a game? Mathematically speaking, a game has players, strategies and scores to explain why the players win or lose. Games which are modelled with differential equations are called differential games. Common examples are pursuit-evasion games...

Computational modelling can be used to reveal insights into the mechanisms of new drugs and to develop new diagnostic tools. Here I will discuss three major diseases: diabetes, hypertension, and autism. I will talk about how we construct models to...

This is the second of a two-part talk. In talk one, I will review various well-known algorithms for integer multiplication, such as schoolbook multiplication, Karatsuba multiplication, FFT multiplication, and the Schoenhage-Strassen algorithm. The...

In this first talk out of two, I will review various well-known algorithms for integer multiplication, such as schoolbook multiplication, Karatsuba multiplication, FFT multiplication, and the Schoenhage-Strassen algorithm. The talk will also be an...

We consider the problem of answering queries about formulas of first-order logic based on background knowledge partially represented explicitly as other formulas, and partially represented as examples independently drawn from a fixed probability...

This talk will focus on two topics in the foundations of neural networks: computability and false structures. In the first part I will recall briefly the concept of recursive functions and then discuss the gap between existence results, the...

Neural networks are remarkable families of non-linear functions that form the backbone for state-of-the-art algorithms in tasks from computer vision (self-driving cars), natural language processing (Google Translate) and reinforcement learning...

We consider an aggregation model that consists of an active transport equation for the macroscopic population density, where the velocity has a nonlocal functional dependence on the density, modelled via an interaction potential. We set up the model...

We explore graphs of high cop number. We give new lower bounds for cop number of graphs of high girth. We also present a new class of undirected graphs with cop number $(1-o(1)) \sqrt{n/2}$ and a class of directed graphs with cop number $(1-o(1))...

A theme that cuts across many domains of computer science and mathematics is to find simple representations of complex mathematical objects such as graphs, functions, or distributions on data. These representations need to capture how the object...
