Bayesian methods are powerful for modelling and integrating multiple types and sources of data. These
methods cross into all areas of data analytics as they represent state of belief via a probability distribution.
The key ingredients for a Bayesian analysis are the likelihood function, which reflects information about
the parameters contained in the data, and the prior distribution, which quantifies apriori knowledge about
the parameters before observing data. The prior distribution and likelihood are then combined to form the
posterior distribution, which represents total knowledge about the parameters after the data have been
observed. In complex models, Markov Chain Monte Carlo (MCMC) methods are used learn about the
posterior distribution. In this talk, I will give an overview of use of various Bayesian modelling frameworks
for network models, state space models and Dirichlet process based models with real world applications.

Dr. Saman Muthukumarana is an Associate Professor in the Department of Statistics at the University of
Manitoba. (https://www.samanmuthukumarana.com/). He is the Dircetor of Data Science Nexus and
Associate Head (Graduate) in the Department of Statistics. His primary research interests lie broadly in
Bayesian methods and computation for complex models which integrate multidisciplinary applications.
Along with this main theme, he has developed methods to facilitate modelling and inference on non-
standard complex data, which lead to innovative analyses in the areas of social networks, health studies,
sports, customer surveys, user behaviour analysis, and environmental and ecological studies.

This research is centered around the integration of computer-vision based perception capabilities with existing machines for the purpose of developing human-machine collaboration applications. In this research a 6-DOF hydraulic manipulator controlled via a haptic device is integrated with a standard HD webcam and two computer-vision-based applications were developed. Vision-based teleoperation is used to control the manipulator through the use of a fiducial marker replacing the haptic device. Additionally, a second application was developed in which a virtual safety wall is created around the manipulator to improve safety in environments where operators work in close proximity to moving machines.

Embedding fiducial markers onto clothing for the use of human identification and tracking was also tested via a third application in which the markers are tracked in a 3D environment to produce a 2D map of the user’s movements along with travel metrics.

ABSTRACT
The goal of this project was to design and implement a control system to balance a single inverted pendulum. One method to implement a control system is state-space formulation. State-space control systems allow for the reduction of the complexity of physical physics, and allows for straight-forward implementation on micro-controllers.

In student laboratories, Quanser’s real time controller could be used to design Simulink block diagrams to control the pendulum. The purpose of this project is to bring the existing control system to a low-cost embedded system which functions as a platform that can implement and test various control system techniques. By writing code in a ubiquitous programming language, C, students and researchers can build upon the state-space controller or implement other controllers. By closing the control loops through an Arduino, the pendulum was successfully balanced.

This talk describes research on the development of autonomous vehicles at the University of Campinas (UNICAMP), Brazil. The talk will focus on modelling and control of two mobile robotic platforms: a robotic airship for monitoring in the Brazilian Amazon, and a scaled multi-traction vehicle for agricultural applications in uneven terrains. Descriptions of both projects will be presented, along with challenges in dealing with control, motion planning and vision estimation.

Dr. Ely Paiva is a Professor in the School of Mechanical Engineering at the University of Campinas (UNICAMP), Brazil (www.fem.unicamp.br/~elypaiva). Previously he was a researcher at the Research Center Renato Archer (CTI), when he served in a team responsible for the modelling, simulation and control of the pioneer AURORA airship which in the year 2000 made the first autonomous flight of an outdoor unmanned airship. Presently, he is on a research leave at Concordia University, where he is working on the area of Optimal Guidance and Motion Planning.
