  • Applying Artificial Intelligence in Medicine: Our Early Results
    Picture a world where your heart can be monitored continuously using a device you could purchase at a Best Buy or Target. Algorithms transform the raw data coming from your watch into diagnoses, and your doctor will be notified when a problem is detected. Today, Cardiogram is taking the first step down that path. We’ve developed an algorithm to use the Apple Watch to detect atrial fibrillation...
  • The Cost of Doing Data Science on Laptops
    At the heart of the data science process are the resource intensive tasks of modeling and validation. During these tasks, data scientists will try and discard thousands of temporary models to find the optimal configuration. Even for small data sets, this could take hours to process. Because of this, data scientists who rely on their laptops or departmental servers for processing power must choose between fast processing time and model complexity. In either case, performance and revenue suffer...

  • Are Pop Lyrics Getting More Repetitive?
    In 1977, the great computer scientist Donald Knuth published a paper called The Complexity of Songs, which is basically one long joke about the repetitive lyrics of newfangled music (example quote: "the advent of modern drugs has led to demands for still less memory, and the ultimate improvement of Theorem 1 has consequently just been announced"). I'm going to try to test this hypothesis with data. I'll be analyzing the repetitiveness of a dataset of 15,000 songs that charted on the Billboard Hot 100 between 1958 and 2017...
  • I don’t know Fisher’s exact test, but I know Stan
    A few days ago, I watched a terrific lecture by Bob Carpenter on Bayesian models. He started with a Bayesian approach to Fisher’s exact test. I had never heard of this classical procedure, so I was curious to play with the example. In this post, I use the same data that he used in the lecture and in an earlier, pre-Stan blog post. I show how I would go about fitting the model in Stan and inspecting the results in R...
  • Google’s neural network-generated custom face stickers are like Bitmoji that aren’t horrible
    So let me just say really quick that I really dislike Bitmoji. Pretty much everything about it/them. The one thing that’s good about Bitmoji is that the user really can easily customize a representative avatar, which is good for inclusion, even if the results are universally terrible in every way. Fortunately Google has just blown Bitmoji out of the water with a genuinely excellent alternative...
  • The Making of the Weighted Pivot Scatter Plot
    I recently published a story that tried to answer the question: what city is the microbrew capital of the US? One of the graphics in the story allows the user to adjust some parameters to change the rankings, and see how the data can be manipulated to yield different results. It looks like this...
  • Understanding deep learning requires re-thinking generalization
    This paper has a wonderful combination of properties: the results are easy to understand, somewhat surprising, and then leave you pondering over what it all might mean for a long while afterwards! The question the authors set out to answer was this: What is it that distinguishes neural networks that generalize well from those that don’t?...
  • From Physics to Finance: My First Year in [Data Science] Industry
    As the first data science hire in a startup, the opportunities to interact with and learn from other groups are limitless. I communicate with engineers, business development, marketing, customer success and design teams on a regular basis: a unique opportunity to learn about the other fields, how different departments operate, and the financial technology as a whole. Here are some lessons I have learned along the way...
