Getting more from less: compressed sensing and its applications

Many problems in science and engineering require the reconstruction of an object - an image or signal, for example - from a collection of measurements. Due to time, cost or other constraints, one is often limited by the amount of data that can be collected. Compressed sensing is a mathematical theory and set of techniques that aim to enhance reconstruction quality from a given data set by exploiting the underlying structure of the unknown object; specifically, its sparsity. In this talk I will commence with an overview of some main aspects of standard compressed sensing. Next, motivated by some key applications, I will introduce several generalizations. First, I will show that compressed sensing is possible, and can in fact has some substantial benefits, under substantially relaxed conditions than those found in the standard setup. Second, time permitting, I will show that compressed sensing - whilst primarily a theory concerning finite-dimensional vectors - can also be extended to the infinite-dimensional setting, thus allowing accurate recovery of functions from small and incomplete data sets.

Working with the D-Wave quantum computer: Modeling, minors, and mitigation

The D-Wave Two (tm) is a quantum annealing processor consisting of 512 qubits operating at a temperature of 10-20 millikelvin. Its native operation finds a low-energy spin configuration in the Ising model on a fixed non-planar graph. In this talk I will give an overview of the system from a mathematician's perspective. Burning issues I will explore include quantumness, minor-embedding, error modeling, and upcoming developments.

Discriminative Latent Variable Models for Human Action Recognition

Developing algorithms to interpret scenes of human activity involves a number of related tasks including human detection, tracking, and action recognition. These tasks are intertwined, information from one can provide assist in solving others. In this talk we will describe discriminative latent variable models to address these tasks together, focusing on the latent SVM / max-margin hidden conditional random field. We will review work a broad swath of work in this area. These methods can be used for jointly recognizing actions and spatio-temporally localizing them in videos. Models for human-human and human-object interactions will be presented. We will present methods for group activity recognition, with holistic analysis of entire scenes of people interacting and taking different social roles.

Mathematics in the computer age: exploration and exposition

Mathematics is the study of provably true statements reachable using logic from an agreed upon set of assumptions. And, while the set of tools we use to prove statements has been largely static for the last few centuries, how we decide what to prove and how to share it with our students/colleagues/etc has undergone a remarkable transformation since the invention of the electronic computer. In this talk, I’ll demonstrate some phenomenon/patterns which are immediately apparent given a computer, and which without would probably have remained hidden from us. These examples give way to some very interesting (and applicable) mathematics, some of which I’ll try to explain. I’ll also talk a bit about how one might use new computer-based tools to share and explain new (or even old!) mathematics. So far, mathematicians have held on to linear modes of communication such as articles, books, etc, and while such things are unlikely to ever disappear, they don’t accurately reflect the true nature of mathematics as a body of knowledge (which is not a single linear progression of ideas, but a complicated highly connected graph), nor do they have the dynamic capacity to demonstrate the “doing" of mathematics. I wish to open a dialog about how modern computer-based tools can tackle the inherent non-linearity of mathematics in such a way as to open the beauty and applicability of mathematics to a wider section of humanity.

Quasisymmetric refinements of Schur functions

Schur functions were introduced early in the last century with respect to representation theory, and since then have become important functions in other areas such as combinatorics and algebraic geometry. They have a beautiful combinatorial description in terms of diagrams, which allows many of their properties to be determined.

These symmetric functions form a subalgebra of the algebra of quasisymmetric functions, which date from the 1980s. Despite this connection, the existence of a natural quasisymmetric refinement of Schur functions has been considered unlikely.

However, in this talk we introduce quasisymmetric Schur functions, which refine Schur functions and many of their properties, as revealed by extensive computer-generated data.

This is joint work with Christine Bessenrodt, Jim Haglund, Kurt Luoto, Sarah Mason, Ed Richmond and Vasu Tewari.

The talk will require no prior knowledge of any of the above terms.

High-Order Finite-Difference Methods for Modelling Electromagnetic Wave Propagation

Finite-difference methods are a popular choice for solving systems of partial differential equations (PDEs) numerically. Throughout my work, I employ finite-difference methods to solve the various systems of PDEs that arise in common electromagnetic problems. One of the most important recent developments in finite-difference methods has been the use of finite-difference approximations with an increasable order of accuracy. The ability to increase the order of accuracy of the employed approximations can considerably improve performance; however, to exploit high-order approximations effectively, it is necessary to clearly understand how to incorporate boundary conditions. This issue, which stands as the biggest barrier to the widespread adoption of high-order methods, will be the subject of the talk.

Simulating Smoke without Volumes

In computer graphics, and visual effects in particular, smoke simulation has become a standard tool. Typically it is modeled with incompressible fluid flow on a 3D grid, tracking soot concentration and velocity in the air, and calculating buoyancy and pressure forces to evolve it forward; volume renderers can take the soot concentration as input to produce the final images. However, this doesn't scale very well, particularly to real-time applications like video games where even the volume rendering alone is unacceptably expensive relative to the rest of the application. This calls for a little more mathematical analysis and algorithmic creativity! In many circumstances, we can model the soot concentration as uniformly smoky inside a region sharply bounded by a dynamically evolving surface; vorticity likewise provides a much more efficient representation of the velocity field. Avoiding any use of volume data, we can get to interactive simulation and highly efficient real-time rendering.

Inference algorithms for continuous time Markov chains over large state spaces

Continuous time Markov chains (CTMCs) is a fundamental modeling tool in time series analysis, phylogenetics and many other areas of statistics. In most applications, simplifying assumptions are typically made to reduce the state space of the CTMCs to a finite and typically small collection of objects (in phylogenetics, for example, the four nucleotides). However, new questions and new data types motivate the development of CTMCs over strings, graphs and other countably infinite spaces. In this talk, I will describe some of our recent work on models and algorithms for analyzing CTMCs over countably infinite space. The first part of the talk will be devoted to the Poisson Indel Process, a model for string-valued CTMCs, and the second part, on inference on CTMCs over other countably infinite spaces. I will focus on applications in phylogenetics, but many of the algorithms and models have potential uses in other branches of applied statistics.

Combinatorial dichotomy classifications

In classifying the complexity of certain homomorphism problems, it sometimes turns out that it is the presence of a combinatorial obstruction in the target structure that causes a problem to become intractable. I will discuss several recent results of this type, including recent joint work with Egri, Larose, and Rafiey.

Automation for the generating series of coloured set partitions

The equidistribution of many crossing and nesting statistics exists in several combinatorial objects like matchings, set partitions, permutations, and embedded labelled graphs. The enumeration of such objects according to their crossing or nesting number has been a challenge, often resulting in hard to solve functional equations.  When both nesting and crossing numbers are bounded, the generating series are rational for (arc-)colouredmatchings, set partitions, and permutations shown by Chen and Guo, Marberg, and Yen respective. We describe algorithms implemented in Maple that give the rational generating series for non-crossing, non-nesting, c-coloured set partitions and permutations. The success of the implementation leads to the possibility of automation for more complicated structures and provides new directions of attack for previously unsolved functional equations.

Influence in Social Networks.

Benjamin Lundell, University of Washington

The behavior of members of a social network has been studied for many years. The traditional approach has been to look at the aggregate behavior of the network, and then average this aggregate over the network's users to determine a "representative member" of the network. In particular, this method assumes that each member acts independently of his or her peers and ignores the influence one member might have on another. In the last ten years, computer scientists and physicists have developed new approaches to studying this problem which are based on the assumption that a members' peers greatly influence his or her behavior. Thus, these models raise the question, "Who are the most influential members of a social network?" In this talk, I'll discuss some ideas on how to answer this question, and share some results of an ongoing project about political influence in the United States. This is joint work with Chris Aholt.

Towards generating random mammalian genomes.

Marni Mishna, Simon Fraser University

Genome arrangements, a major mechanism of evolution, shuffle genetic material along chromosomes. Thus, a now standard approach models groups of close genomes as signed permutations. The correct data structure to study permutations in this context is the common interval tree. In this talk we will describe the process of considering tree parameters to refine the class of common interval trees (hence permutations) to those that represent mammalian genomes well. These refinements are particularly amenable to Boltzmann random generation and analytic enumerative techniques. Work in collaboration with Mathilde Bouvel, Cedric Chauve, Rosemary McCloskey, Cyril Nicaud and Carine Pivoteau.

Formal Identification of DC Operating Points in Integrated Circuits and some Lessons in (Ir)Reproducible Research in Computational Math

Ian Mitchell, University of British Columbia

A DC operating point is an equilibrium toward which a circuit will be drawn for sufficiently nearby initial conditions when any inputs are held fixed.  DC operating points may or may not be desirable features in a circuit -- in an oscillator they represent lockup, but in a memory element they are the mechanism whereby discrete state is
stored.  Consequently, it is useful to identify a circuit's DC operating points.  Because the circuit is naturally drawn towards them, the most common technique to identifying such equilibria is through simulation; however, it is quite possible for the domain of attraction of an equilibrium to be small enough that simulation is unlikely to find it, yet large enough to cause occasional problems.

In joint work with Mohamed Zaki & Mark Greenstreet, we strung together a collection of public software from the formal verification and numerical analysis communities to rigourously identify and classify all potential DC operating points for surprisingly complex circuit models.  Unfortunately, the resulting workflow has proved fragile, and significant effort would be required for reproduction and/or extension.  In the second half of the talk I will discuss some tools and techniques that would have significantly improved the reproducibility of the results had they been adopted.

Venn diagrams and tatami tilings: vignettes from computational mathematics.

Frank Ruskey, University of Victoria

In this talk I will explain how computation has helped me and my students in resolving certain mathematical questions, via two specific recent examples. In the first example, we consider the problem of constructing a simple rotationally symmetric 11-Venn diagram. This problem was open for about 40 years and several incorrect solutions were proposed. Initially the problem seemed to be beyond the reach of exhaustive searches, but our recognition of a new type of "near-symmetry" in Venn diagrams suggested that searching in a certain reduced solution space might be fruitful --- which indeed it was. In the second example, we consider a tiling problem first investigated by Don Knuth. On the basis of his computations it seemed that the generating function for counting those tilings was I(z)*S(z) where I(z) was a mysterious irreducible polynomial and S(z) was a well structured and predictable. We have proved that S(z) is what it seemed to be, and revealed many interesting properties of the irreducible I(z), but its exact expression is still not known. [The students mentioned above are Khalegh Mamakani and Alejandro Erickson.]

Spectral Analysis and Dynamical Behavior of Complex Networks.

Ljiljana Trajkovic, Simon Fraser University

Discovering properties of the Internet topology is important for evaluating performance of various network protocols and applications. The discovery of power-laws and the application of spectral analysis to the Internet topology data indicate a complex behavior of the underlying network infrastructure that carries a variety of the Internet applications. In this talk, we present analysis of datasets collected from the Route Views and RIPE projects. The analysis of collected data shows certain historical trends in the development of the Internet topology. While values of various power-laws exponents have not substantially changed over the recent years, spectral analysis of matrices associated with Internet graphs reveals notable changes in the clustering of Autonomous Systems and their connectivity.

Looking for lost genomes

Cedric Chauve, SFU

Paleogenomics aims at reconstructing the genomes of extinct species, whose DNA can not be sequenced due to molecular decay. Hence the only possible approach is the study of current genomes (i.e. descendants of these extinct species) to detect conserved features that might indicate ancestral genomic characters and then to assemble these characters into ancestral genomes. Although the initial question is clearly biological, it can only be answered through an inference process that relies on both a mathematical model for ancient genomes and computational methods within this model. In this talk, I will present recent results on this problem, that rely on relatively old combinatorial notions such as the Consecutive Ones Property of binary matrices and PQ-trees.

Viral load in treated HIV+ individuals modeled using branching processes

Jessica Conway, UBC

I will discuss a stochastic model of within-host HIV viral dynamics. The modeling is motivated by observations of viral load in HIV+ patients on anti-retroviral treatment: though the treatment very effectively inhibits viral replication, a treated HIV+ individual's viral load remains non-zero. Further, blood tests show occasional "viral blips," short periods of increased viral load. We adopt the hypothesis that this low viral load can be attributed to activation of cells latently infected by HIV before treatment initiation. Blips would then represent small-probability deviations from the mean. Modeling this system as a branching process, we compute probability distributions for viral load using a novel numerical approach. These distributions yield blip amplitudes consistent with patient data. We then compute probability distributions on duration of these blips through direct numerical simulation. Our stochastic model of latent cell activation reproduces features of treated HIV infection, and can be used to provide insight into variability of treatment outcomes for HIV+ individuals not available in deterministic models.

Homomorphisms to Clebsch, proof by computer

Matt DeVos, SFU

Computer proofs are nothing new in graph theory... after all our most famous theorem, the Four Colour Theorem, was proved by a computer 35 years ago. I will discuss this and other computer proofs in graph theory, then detail a recent contribution of this type due to Robert Samal and myself. We give a computer proof that every cubic graph of girth at least 17 has a homomorphism to the Clebsch Graph.

Searching for a maximum set of mutually orthogonal Latin squares of order 10

Wendy Myrvold, UVic

A Latin square of order n is a n×n array of n symbols such that each symbol appears exactly once in each row and exactly once in each column. Two Latin squares of order n are orthogonal if, when superimposed, each ordered pair of symbols occurs exactly once. One of the big unsolved problems in design theory is to determine if it is possible to find three or more pairwise orthogonal Latin squares of order 10. This talk describes both theoretical and computational attempts at resolving this question. The talk will conclude with some suggestions for promising areas for continued search.

The research presented in this talk was done in collaboration with Russell Campbell, Erin Delisle, Mark Ellingham, Leah Howard, Nikolay Korovaiko, Brendan McKay, Alison Meynert, and Ian Wanless.

Discrete geometric game interpretations of nonlinear elliptic partial differential equations

Adam Oberman, SFU

In this mostly nontechnical talk, I will present discrete geometric games, which in simple cases you will be able to solve on a blackboard. Starting with familiar games, such as random walks, we will add new twists (choosing biased diffusions, exit strategies, random turns).

These games lead to interpretations and effective solution methods for nonlinear partial differential equations which appear in areas such as: Differential Geometry, Stochastic Control, Mathematical Finance, and Homogenization. Typical examples include: Hamilton-Jacobi equations, the Monge-Ampere equation, and the equation for the Convex Envelope.

Location: Talks will be held in the IRMACS Centre's Presentation Studio. The poster session will be held in the IRMACS Centre's Atrium.
