is a data visualization researcher
based in Montreal, Canada.
In 2005, I was contracted to create a program to support research into the application of a statistical technique called Kernel Density Estimation to the study of global poverty. The result of this contract (which I worked on with my friend and occasional colleague David de Koning) is the Kernel Density Estimation and Analysis tool which I have just released on Github under an open-source license.
The research (which, to be clear, wasn't done by me) resulted in a very interesting paper called Kernel Density Estimation Based on Grouped Data: The Case of Poverty Assessment.
In 2003, I wrote a neat and powerful piece of software called Galapagos for my 4th-year undergraduate thesis (download PDF). It was a framework for the development of advanced (i.e. distributed, parallel and/or hybrid) evolutionary algorithms, applicable to a wide range of computational challenging optimization problems. I applied it to a variety of transportation-related problems at the University of Toronto.
I was invited to speak on a panel at a Rubicon Project product launch, and this is the video of the event.
There’s an organization in Montreal I think is awesome called Santropol Roulant which, among other things, has a meals-on-wheels operation. They have hundreds of volunteers and wanted to upgrade the system they used to store their volunteer information, so I helped them out, and I’ve open-sourced the results, in case any other non-profit wants a very simple volunteer-list management system.
This is the machine-readable back of my new nerdy QR-code business card!
There doesn't appear to be a good Wikipedia entry for RTB for me to link at the moment, when I want to blog about it so I'll draft my own explanation here. (Edit: there is an entry now, but I like my characterization better!) Keep in mind while reading this that I'm looking at RTB as a software engineer with an interest in economics, rather than as an ad industry veteran!
One of the things we do at Datacratic is to use machine learning algorithms to optimize real-time bidding (RTB) policies for online display advertising. This means we train software models to predict, for example, the cost and the value of showing a given ad impression, and we then incorporate these prediction models into systems which make informed bidding decisions on behalf of our clients to show their ads to their potential customers.
This is a screenshot of what I pull up on my iPhone every morning now after its alarm clock wakes me up. That's right, it's an interface to turn on my espresso machine so that it will warm up to a specific temperature by the time I'm done snoozing! I can even look at a real-time plot of the temperature to confirm that it's holding where it should be and doesn't need to bumped up or down a degree.
