  • Can deep learning help find the perfect girl?
    When a Machine Learning PhD student at University of Montreal starts using Tinder, he soon realises that something is missing in the dating app - the ability to predict to which girls he is attracted. Harm de Vries applies Deep Learning to assist in the pursuit of the perfect match...
  • Searching for Approximate Nearest Neighbours
    Nearest neighbour search is a common task: given a query object represented as a point in some (often high-dimensional) space, we want to find other objects in that space that lie close to it. For example, a mapping application will perform a nearest neighbours search when we ask it for restaurants close to our location. Nearest neighbour search underpins two crucial systems at Lyst...
  • “Don’t Invert That Matrix” – Why And How
    The first time I read John Cook’s advice “Don’t invert that matrix,” I wasn’t sure how to follow it. I was familiar with manipulating matrices analytically (with pencil and paper) for statistical derivations, but not with implementation details in software...We’ll chug through a computation example below, to illustrate the difference between these two methods. But first, let’s start with some context: a common statistical situation where you may think you need matrix inversion, even though you really don’t...
  • Learning from the experience of others with mixed effects models
    At Stitch Fix we have many problems that boil down to finding the best match between items in two sets. Our recommendation algorithms match inventory to clients with the help of the expert human judgment of our stylists. We also match these stylists to clients. This blog post is about the remarkably useful application of some classical statistical models to these and similar problems that feature repeated measurements...
  • The Definitive Guide to Do Data Science for Good
    You are a fully-equipped (or aspiring) data scientist and want to use your precious skills for solving problems that really itch the world? Welcome to the club. The good news is that there are many ways for data scientists to do good. However, the path is not always beaten and you might need to show some initiative.

  • Automate the Boring Stuff with Python:
    Practical Programming for Total Beginners
    Recent release recommended by a couple of our readers...
    "Introductions to python are easy to find -- but at the end of the day most python tutorials for beginners end up being the same lessons repackaged, often leaving the new programmer with gaping holes in how their newly acquire skills can be applied practically. This is not one of those books..."... For a detailed list of books covering Data Science, Machine Learning, AI and associated programming languages check out our resources page...
