August 19-23, 2019: Summer School on Data Science Tools and Techniques for Modelling Complex Networks

Dr. Francois Théberge, along with co-presenters Dr. Pawel Pralat, Dr. Bogumil Kaminski and Dr. Przemyslaw Szufel are presenting a week-long summer school on representing and analyzing relational data at the Fields Institute for Research in Mathematical Sciences. In a relational data set, an observation involves two or more entities. Such data sets are often modeled via graphs or hypergraphs. A graph is a collection of vertices representing the entities, connected via edges, each of which represents a relationship between two vertices. Hypergraphs are used to model relations involving an arbitrary number of entities. Exploratory data analysis over relational data can be challenging. Slicing or sampling a relational data set tends to destroy its structure and not much can be learned from it. The missing or noisy data problem is also more problematic with relational data. For example, the addition or removal of an edge in a graph can considerably change properties such as the diameter.

The course will explore various theoretical and practical aspects of relational data representation and mining. The format of the course will be a mix of lectures and demonstrations of various techniques over relational datasets using Python, Julia and Jupyter Notebooks.

About the TIMC

The Tutte Institute for Mathematics and Computing (TIMC) is a government research institute focused on research in fundamental mathematics and computer science. Our members work on highly sophisticated problems and tackle advanced mathematical challenges of importance to the Government of Canada and for the benefit of the nation.


History of the TIMC

The TIMC was opened in 2011 as a special research institute that is supported and funded by the Communications Security Establishment (CSE). Located just east of downtown Ottawa, Canada, our specialized work space is housed within CSE’s world-class, LEED Gold facility.

The TIMC is named after Dr. William T. Tutte, a British-born Canadian codebreaker and mathematician, credited with breaking the Lorenz cipher used by the German High command during World War II. Dr. Tutte’s foundational work in graph theory and matroid theory is world-renowned.



The TIMC is focused on four key research areas: cryptography, cyber security, data science, and quantum computing. We draw upon many mathematical and computational fields, including Algebra, Algebraic Geometry, Combinatorics, Data Science, Topology, Number Theory, and Quantum Computing. Our researchers are leaders in their fields and work in a collaborative fashion on interesting challenges found only within the TIMC.

TIMC researchers benefit from access to some of the fastest computers in the country, as well as cutting-edge technology that is unmatched in Canada. Our work supports CSE’s mission to provide and protect information of national interest.



The TIMC offers a range of opportunities for collaboration and support of mathematics and computer science in Canada. Mathematicians, Data Scientists and Computer Scientists at Canadian universities, or those at international institutions holding Canadian citizenship, can make either short-term or long-term working visits to the TIMC.

The TIMC employs full-time mathematicians and computer scientists holding PhDs in a variety of fields. Their numbers are supplemented by long and short-term academic contractors. We count many distinguished Canadian mathematicians, from a number of Canadian universities, as our current collaborators and alumni.

Canadian academics may work at the TIMC on short-term contracts for a minimum of two weeks over the course of a year. These working visits are arranged to accommodate the visiting researcher’s schedule, and can be spread throughout the year. Visiting researchers work in a collaborative environment on challenging problems, engaging with TIMC staff, other academic contractors and members of partner research institutes. Longer term contracts are also available.


Collaboration and Partnerships

Collaboration and partnership is integral to the work of the TIMC. Our partners include universities across Canada, as well as various classified and government research institutes:

The TIMC is continually working to strengthen and develop partnerships with research institutes, governmental agencies, industry and universities.
