Mathematics Tutor Dr. Richard Hoshino and student Maximilian Kahn ‘19 share exciting news about publishing a paper and going to the annual Association for the Advancement of Artificial Intelligence (AAAI) Conference.

Quest Mathematics Tutor Richard Hoshino attended the annual Association for the Advancement of Artificial Intelligence (AAAI) Conference in New Orleans this year along with 16 students. Two of those students, Max Notarangelo ’19 and Maximilian Kahn ’19, co-wrote papers with Richard that were accepted for the upcoming AAAI 2019 in Honolulu!

“The annual AAAI Conference is easily the most prestigious AI conference in the world, where the world’s top AI researchers submit papers to be presented,” said Richard. “The prestige of AAAI comes from its historically low acceptance rate of papers (usually around 20 to 25%, although it was only 16% this year).”

During the conference, a professor who created an original game called “Birds of a Feather” proposed an Undergraduate Research Challenge for students to analyze this original game, to be presented at AAAI 2019.

For Maximilian Kahn, the AAAI Conference was an eye-opening and mind-expanding experience.

“Seeing what leading researchers were working on—everything from generating pop music using neural networks to creating machines with imagination—made me realize that there are a lot of exciting things we can do with AI in addition to self-driving cars,” he said. “One of the reasons why I am such a big fan of AI is because of the versatility the field offers. For the pragmatists there is machine learning, which can be used to solve problems such as identifying malignant tumours in patients, traffic scheduling, and facial recognition.”

But AI offers a lot more, according to Maximilian.

“There are more foundational areas that can be explored that will excite the theorist, such as defining the notion of causality,” he said. “That is to say, we as humans have an intuitive notion of what causality is, but how can we imbue within AI this same notion? The answer is we have to make ‘causality’ mathematically rigorous.”

Maximilian said he originally hadn’t thought about penning a research paper.

“At first I was not planning on submitting anything because I didn’t think I would meet the submission deadline, but I decided to send a draft of the paper to Richard anyway and he advised that I submit it to the conference,” he said. “While the paper was accepted, it was also torn apart by the reviewers, and so Richard was instrumental in helping me reconstruct the paper to fit the standards of EAAI and ultimately turn it into something I am extremely proud of.”

Maximilian said he would not be attending the AAAI2019 Conference in Honolulu, but he would have Hoshino present his paper.

“I unfortunately will not be able to make it to the conference in Honolulu this year, but Richard has kindly said that he will present the paper on behalf of both of us,” he said. “Richard and I will be presenting our research at the Canadian Mathematical Society’s Winter Meeting in Vancouver this December.”

Max Notarangelo is currently in Budapest on exchange this semester, so he will not be at the Mathematical Society event. He will present his paper, along with Hoshino, in Honolulu.

Confused about the BC referendum? Still not sure how to vote? Our Canadian politics expert has answers.

Q: What are voters being asked to decide?

A: They’re being asked to choose between keeping the current First-Past-the-Post system (FPTP) or changing to Proportional Representation (PR). The first thing to note is that neither system is clearly superior. Both are legitimate voting structures, but they represent different philosophies.

Q: Can you explain FPTP and why some people criticize it? 

A: Right now, each voter in BC casts a ballot in one of 87 electoral ridings. If a candidate gets more votes than any other, they win and become the riding’s representative in the provincial legislature. This person is called a Member of the Legislative Assembly (MLA). It’s very common that the winning candidate in each riding gets less than a majority of the votes. That means a political party can receive a much greater number of seats than is reflected by their actual share of the vote.

In 2005, the BC Liberals won 46 seats (58%) with 45.8% of the vote, while the NDP won 33 seats (13 fewer, 41%), despite the fact that they received only 4% fewer votes. The Greens got 9.2% but did not get a single seat. In 2001, the BC Liberals won 57% of the vote and 77 of the then 79 ridings—which is 97.5 % of the seats. The NDP won just two seats with 21.6% of the vote. The Greens got no seats despite winning 12.4 per cent of the vote.

This winner-take-all system often creates a majority government, which has its pros and cons.

Pros: the governing party can carry out a mandate without worrying about losing power. It’s stable. And there’s clear accountability, because every riding has one MLA, so people know who represents them in Victoria. For Squamish, it’s Jordan Sturdy right now. If people want to reach out to their MLA, it’s straightforward.

Cons: under the current system, 60% of voters often vote against the winner, but their vote has no impact on the outcome. They might have voted for a third party in large numbers, and, if that party doesn’t get a seat, they may feel as if their vote didn’t count. We also have to ask whether stability is actually good for democracy; the previous BC Liberal Government lasted for 16 years winning only approximately 45% of the vote in every election after 2001. So there is a question here: is it a functional democracy when a party can receive less than a majority of the vote and stay in power for such a long time? And what matters more to you? Stability and legislative efficiency or accountability and proportionality? The answer is not easy.

Q: The referendum lists three different kinds of PR. This confuses many people! Can you break it down?

A: Mixed Member Proportional is used in both Germany and New Zealand. The version that’s being proposed in BC is that 60% of MLAs would be directly elected under the First-Past-The-Post system, and the other 40% of seats would be distributed to ensure seat totals reflect the popular vote. This is done by creating a new class of Regional MLAs elected from party lists.  New Zealand changed from FPTP to PR back in the 1990s, and this is the type they use.

Dual Member Proportional is a much newer idea and more complicated. In Rural areas, the single member ridings would remain the same.  In urban areas, ridings would be combined to ensure two members per riding.  The first seat would be awarded to a party to ensure proportionality in the legislature as a whole.  What is unclear is how they would determine how to allocate those extra seats. As this is a new system, we don’t have an example to look at as to how this would be done.

Rural-Urban Proportional combines two different systems for urban and rural parts of the province. In urban ridings, Single Transferable vote would be used. Candidates would be ranked on a single ballot in large ridings with multiple members elected. The candidate with the fewest votes would be dropped and votes redistributed to the second choice on each ballot. The process would continue until one candidate had 50% plus one of the votes.  This is used in Ireland. The rural ridings would be determined using the Mixed Member Proportional system described above.

In short, PR systems provide greater proportionality and force parties to cooperate.  This is because proportional systems are less likely to lead to majority governments.  Parties must make agreements between themselves to create governments. This doesn’t necessarily mean that they’ll need to form coalitions (multiple parties in cabinet at once), but agreements like the one the NDP and Greens have right now in BC would be required more often. And none of the systems in the BC referendum would be expected to be as unstable as some other PR systems.

PR systems can also be more complex and less stable: governments fall more often than in Single Member First-Past-The-Post systems. Ultimately, voters need to decide what they value in making their decision.

Q: What is your own view?

A: New Zealand offers an example of a successful adaptation from FPTP to PR through a Mixed Member Proportional system, and this seems to me to be a good option for BC. Ultimately, how you vote will be based on what you value. I like stability and the strong policy-making capacity of governments under FPTP, but I want to see parties cooperate more and I don’t believe a system that creates such long-lasting governments as we’ve seen in BC is good for democracy.  So, I’m inclined to lean towards a change and, because it is tried, tested and relatively simple, to MMP.

Q: Where can people get more info?

A: It’s best not to be swayed by the rhetoric of political leaders. Look for more neutral information from Elections BC, which was mailed out along with the ballots and can be viewed at elections.bc.ca/referendum.  Doug Munroe and I also did a podcast discussion which can be found here: https://sea2skypodcast.com/2018/10/29/bc-electoral-reform/

Marjorie shells out a rare collection for her Marine Zoology class.

You use a collection of seashells for your Marine Zoology class. What is special about it?
The collection is extraordinary and contains over 300 shells—too many to use in a single Block. It is from all over the world and truly showcases the diversity within and across taxa, revealing a dramatic range of features, including growth, form and function.

What’s the benefit to students?
Working hands-on with a collection is a much richer experience than just seeing photos and diagrams. The students study the seashells while preparing them for display, and they learn so much in the process, including the way the animals adapted to a range of predators and habitats. For example, some shells showed evidence of predator drill-holes, breakage and subsequent repair.  Preparing the exhibit is also a great foundation for the field trip to Bamfield Marine Sciences Centre later in the Block, where students work with live animals.

Who donated the collection?
Most of the shells were donated by Dr. Penny LeCouteur, a visiting Chemistry Tutor in Quest’s earlier years. I am donating a smaller collection, which I got from my colleague Dr. David Secord. Penny and David gathered the shells along their travels, and the students plan to interview them to learn more.

Anything else we should know?
Yes. The class read several papers by a leading scientist in the field, who does much of his work on shell morphology by touch because he is blind. The students created a black-box exhibit that invited viewers to feel the shells without seeing them, to challenge them to find out whether they too could detect shell growth and damage patterns simply by touch. It is a remarkable experience for both the students and the viewers—it teaches them to appreciate the attention to detail required, and the degree of expertise acquired, when working mainly through touch.

Quest Arts and Humanities/Mathematics Tutor Dr. Darcy Otto gives us the highlights of his recent sabbatical, and shares some thoughts on Artificial Intelligence (AI).

You were recently on a sabbatical. Where did you go, and for how long?

I went to Carnegie Mellon University in Pittsburgh for one year. The main purpose was to write the first draft of a book called The Promise of Quantum Computing and Artificial Intelligence, where I look at the nature of computation, and ask how breakthrough approaches in QC and AI change how we think about computation. At CMU, I got to study and discuss these ideas with some of the biggest names in the foundations of Mathematics and Computer Science.

Most people have the idea that a sabbatical is a vacation of sorts, but it is work, right?

Sabbatical is certainly work. The aim is to pursue a research agenda that would otherwise not be possible given other duties, such as teaching and university service. But it is more than that. A sabbatical allows us to model the sort of lifelong learning and exploration that we encourage in our students. To break ground on a topic that is new, we need a period of sustained study and thought. A sabbatical informs our research and teaching for years after the sabbatical ends.

Why does the subject of AI interest you?

There has been serious research into AI since the 1950s. But in the last decade, there have been several important breakthroughs in AI that have allowed the field to flourish. We can see AI emerging everywhere: driving our cars, aiding in medical diagnoses, deciding what we see in our social media feeds, categorizing images, converting voice to text, and more. I was drawn to study AI because I want to understand the principles that underpin all these developments.

Should we be worried about some sort of Terminator-type scenario?

The goal of AI is to make decisions as well as, or better than, humans. But if you look at the areas to which AI is applied, the domain is always very specific. We have an AI that plays chess, or perhaps one that drives a car.

We are a very long way from the sort of general intelligence that would give rise to the Terminator. When we get an AI that can both build flat-pack furniture and fly a helicopter, it might be time to think about where we are going.

What is the next step in the process for this book?

The next step is to finish a full draft. I will be using the Quantum Computing chapter of my book in my upcoming Computer Science class (in Fall Block 2). So my work on sabbatical has a direct application to my teaching this year.

What did you miss most about Quest while you were away?

I missed the easy way interdisciplinary makes an appearance in the intellectual discourse. While at Carnegie Mellon, I had the great privilege to spend time with philosophers, physicists, and computer scientists. But coming back and coordinating Cornerstone made me realize how much I missed discourse with friends and colleagues in other fields.

I just had a great discussion about dolphins in ancient art and modern poetry, for example. I also missed being in the classroom. It is always exciting to be able to share what I’ve learnt with students who are willing to follow a question wherever it leads.

Chief Academic Officer (CAO) and cave rescuer Doug Munroe spoke to the CBC about the race to rescue 12 Thai schoolboys stranded with their soccer coach in a flooded cave in Thailand.
