  • Data-mined photos document 100 years of (forced) smiling
    By studying nearly 38,000 high-school yearbook photos taken since 1905, UC Berkeley researchers have shown just how much smiling, fashion and hairstyles have changed over the years. The goal was not just to track trends, but figure out how to apply modern data-mining techniques and machine learning to a much older medium: photographs...
  • Wikipedia Bets On AI To Rebuild Editor Ranks
    Wikipedia will leverage a new machine learning service called ORES to automate reviews of revisions to flag ones that are problematic and make it easier for human editors to get their proposed revisions approved...
  • Simple end-to-end TensorFlow examples
    I flew from Austin to Washington DC last week, and the morning before my flight I downloaded TensorFlow, made sure everything compiled, downloaded the necessary datasets, and opened up a bunch of tabs with TensorFlow tutorials. My goal was, while on the airplane, to run the tutorials, get a feel for the flow of TensorFlow, and then implement my own networks for doing some made-up classification problems. I came away from the exercise extremely pleased. This post explains what I did and gives pointers to the code to make it happen...
  • Is Bayesian A/B Testing Immune to Peeking? Not Exactly
    Since I joined Stack Exchange as a Data Scientist in June, one of my first projects has been reconsidering the A/B testing system used to evaluate new features and changes to the site. Our current approach relies on computing a p-value to measure our confidence in a new feature. Unfortunately, this leads to a common pitfall...
  • Regularizing RNNs by Stabilizing Activations
    We stabilize the activations of Recurrent Neural Networks (RNNs) by penalizing the squared distance between successive hidden states' norms. This penalty term is an effective regularizer for RNNs including LSTMs and IRNNs, improving performance on character-level language modelling and phoneme recognition, and outperforming weight noise...
  • Machine Intelligence In The Real World
    I’ve been laser-focused on machine intelligence in the past few years. I’ve talked to hundreds of entrepreneurs, researchers and investors about helping machines make us smarter. On average, people seem most concerned about how to interact with these technologies once they are out in the wild. This post will focus on how these companies go to market, not on the methods they use....
