  • Symposium: Computational Thinking in Mathematics Education

    Professor Buteau is organizing a 3-day symposium, titled Computational Thinking in Mathematics Education, on October 13-15, 2017. The event, funded by the Fields Institute for Research in Mathematical Sciences, will be hosted at UOIT and is organized together with Dr Namukasa (UWO), Dr. Gadanidis (UWO), Dr. Kotsopoulos (Huron College), and Dr. Hughes (UOIT). A ‘Maker Day‘ workshop for prospective and in-service teachers will be hosted during the day on October 13, 2017 prior to the symposium. See the poster or ctmath.ca for more details or contact Professor Buteau.

    Heterogeneous Particle Swarm Optimizers: Scalability,
    Self-Adaptive Behaviors, and Dynamic Environments

    Abstract: Particles in the standard particle swarm optimization (PSO) algorithm, and most of its modifications, follow the same behaviours. That is, particles implement the same velocity and position update rules. This means that particles exhibit the same search characteristics. Heterogeneous PSO (HPSO), on the other hand, allow particles to follow different search behaviours selected from a behaviour pool, thereby efficiently addressing the exploration–exploitation trade-off problem.

    This talk will provide an overview of very simple HPSO algorithms, and will provide empirical results to show that they are more efficient than the homogeneous PSO algorithms making up the behaviour pool of the HPSO algorithm. The talk will also discuss the HPSO scalability properties, and will present approaches to self-adaptive behaviour selection. The talk will end with an illustration of the performance of simple HPSO algorithms in dynamic environments.

    Professor Andries Engelbrecht is the South African Research Chair of Artificial Intelligence in the Computer Science Department, University of Pretoria

  • Mahsa Daneshmandmehrabani thesis defense

    When: July 17, 2017 – 1:00pm – 3:00pm

    Ms. Mahsa Daneshmandmehrabani will defend her M.Sc. on Monday July 17, 2017 at 1:00 PM in Mackenzie Chown C206.

    Abstract: We develop a recommendation algorithm for a local entertainment and ticket pro-vider company. The recommender system predicts the score of items, i.e. event, for each user. The special feature of these events, which makes them very differ-ent from similar settings, is that they are perishable: each event has a relatively short and specific lifespan. Therefore there is no explicit feedback available for a future event. Moreover, there is a very short description provided for each event and thus the keywords play a more than usual important role in categorizing each event. Moreover, we provide a hybrid algorithm that utilizes content-based and col-laborative filtering recommendations. We also present an axiomatic analysis of our model. These axioms are mostly derived from social choice theory.

  • Physics and Mathematics Seminar: Are there trajectories in phase space of quantum systems?

    When: March 28, 2017 – 2:00pm – 3:00pm

    Ole Steuernagel (University of Hertfordshire and Brock University) will be giving a seminar entitled Are there trajectories in phase space of quantum systems? The talk will take place at 2:00 pm on Tuesday, March 28, 2017 in Mackenzie-Chown H-block room 313.

    Abstract:

    Phase-space dynamics in classical mechanics is described by transport along trajectories. It is thought by some that Heisenberg’s uncertainty principle does not allow for trajectories in phase space: that is incorrect. Here, I will explain what a phase space trajectory is.  Then I show that e.g. harmonic oscillator dynamics can be described with trajectories.But anharmonic quantum mechanical systems do not allow for a trajectory-based description of their phase-space dynamics. This invalidates some approaches to quantum phase-space studies.

    An abstract plausibility argument against phase space trajectories in general is given. Then an explicit proof for all quantum phase-space distributions with negative values follows. This proof shows that the generation of coherences in anharmonic quantum mechanical systems is responsible for the occurrence of singularities in their phase-space velocity fields, explaining the numerical problems repeatedly reported in the literature. Our investigation provides deeper insight into the nature of quantum phase-space dynamics.
