Artificial Intelligence (and Games)
Jonathan Schaeffer, Professor of Computing Science at the University of Alberta

Artificial Intelligience

In McKinsey & Company’s Disruptive Technology, technologies containing artificial intelligence (AI) are expected to create tens of trillions of dollars in economic impact by the year 2025. Similarly, Gartner, Inc. lists machine learning (a subset of AI) as one of the top 10 strategic technology trends for 2017. Yet another technology fad? Perhaps, but it is hard to imagine any industry that won’t be affected by software applications with “smart” capabilities.
In this talk we present a gentle introduction to artificial intelligence, its past successes, current efforts, and future impact. AI is widely deployed today, but its presence and impact remains largely hidden from the average consumer. All that will change within a decade.

Jonathan Schaeffer is a Distinguished University Professor of Computing Science at the University of Alberta and is currently the Dean of the Faculty of Science. His research are is artificial intelligence. He is best known for applying his research to computer games. He is the creator of the checkers program Chinook, the first program to win a human world championship in any game. In 2007 he announced that checkers was solved: perfect plays leads to a draw. He is a founder of Onlea (, the world’s first MOOC production company.

The “Historic” Paris Climate Agreement: What It Means for Canada and Alberta –
Dr. Sharon Mascher, Professor, University of Calgary

Paris Climate Change

On 4 November 2016, the Paris Agreement entered into force. Hailed by many around the world as ‘historic’, the Paris Agreement is intended to strengthen the global response to climate change. However, as Prime Minister Trudeau noted in a Statement issued following the conclusion of the Paris climate conference, “[t]here is much tough work that still needs to be accomplished both at home and around the world to implement the agreement.” But what commitments have the Parties to the Paris Agreement made? What do these commitments mean here at home in Canada and in Alberta? In this presentation, Sharon will discuss these and other questions to help provide you with an understanding of legal framework developing around the issue of climate change.

Dr Mascher is a Professor in the Faculty of Law at the University of Calgary. Her research and teaching focuses on intersections between environmental law, energy law and the law affecting aboriginal people. For the last several years, her research has had a particular emphasis on the legal and policy framework relating to climate change.
