Note: This is a silly application. Don’t take anything seriously.
Benford’s law describes a phenomenon where numbers in any data series will exhibit patterns in their first digit. For instance, if you took a list of the 1,000 longest ri...

Inspired by Sander Dieleman’s internship at Spotify, I’ve been playing around with deep learning using Theano. Theano is this Python package that lets you define symbolic expressions (cool), does automatic differentiation (really cool), ...

Many years ago, I used to think that A/B tests were foolproof and all you need to do is compare the metrics for the two groups. The group with the highest conversion rate wins, right?
Then, for a long period, I ran a lot of tests. I sta...

I’ve been spending quite some time lately playing around with RNN’s for collaborative filtering. RNN’s are models that predict a sequence of something. The beauty is that this something can be anything really – as long as you can design ...

One obvious thing to anyone living in NYC is how tourists cluster in certain areas. I was curious about the larger patterns around this, so I spent some time looking at data. The thing I wanted to understand is: what areas are dominated ...

During my time at Spotify, I’ve reviewed thousands of resumes and interviewed hundreds of people. Lots of them were rejected but lots of them also got offers. Finally, I’ve also had my share of offers rejected by the candidate.
Recruiti...

From my presentation at MLConf, one of the points I think is worth stressing again is how extremely well combining different algorithms works.
In this case, we’re training machine learning algorithms on different data sets (playlists,...
