  • The Programmer’s Guide to Booking a Plane
    About two months ago, I wanted to go on a vacation. I had the hotel more or less picked out, but the transportation was still up in the air. I began by scouring the web for cheap plane tickets, like normal travel folks seem to do. I scoured all of the fancy airlines, but all of their fares were too high for my liking...
  • The Moving Sofa Problem
    The mathematician Leo Moser posed in 1966 the following curious mathematical problem: what is the shape of largest area in the plane that can be moved around a right-angled corner in a two-dimensional hallway of width 1? This question became known as the moving sofa problem, and is still unsolved fifty years after it was first asked...

  • White House Special with DJ Patil, US Chief Data Scientist
    We went to the White House to interview DJ Patil, the Chief Data Scientist of the United States. DJ talked with us about the relationship between government and Silicon Valley, the White House’s leadership on data ethics, and why the first US Chief Data Scientist was actually George Washington...

  • Quantifying and Visualizing “Deep Work”
    One of the best books I read in 2016 is Cal Newport’s “Deep Work”. In his book Cal explains that technology and various social practices have eroded our capacity to work without distractions and that we need to find ways to spend more time doing what he calls “Deep Work”: long stretches of time of uninterrupted full-focus work. For the end of 2016 I decided to do a more systematic analysis than usual and to share it with the world thinking that: (1) you may be interested in doing the same and (2) you may have ideas on how to improve the process...
  • Which programming languages have the happiest (and angriest) commenters?
    It’s officially winter, so what could be better than drinking hot chocolate while querying the new Stack Overflow dataset in BigQuery? It has every Stack Overflow question, answer, comment, and more — which means endless possibilities of data crunching. Inspired by Felipe Hoffa’s post on how response time varies by tag, I wanted to look at the comments table (53 million rows!)...
  • Pharma adopts data-science culture in move toward AI
    To whom does pharma turn when facing cutting-edge research challenges such as designing algorithms to comb unstructured EHR data hunting for undiagnosed patients? Who helps glean patient insights from digital data streams such as social media? Who is designing the value-based frameworks behind pharma's latest wave of performance-based agreements with payers? These are just some of the tasks being fielded by data scientists, a new kind of insight and analytics professional showing up in the biopharma ranks...
  • Building a Brazillian Jiu-Jitsu family tree
    Here, I will visualize the lineages of hundreds of elite BJJ practitioners drawn from the website BJJ heroes. I feel that lineages are intrinsically interesting; they allow BJJ practitioners, such as myself, to better understand our place in the context of an increasingly popular sport. Moreover, to the extent that style is transmitted through master-student relationships, practitioners who are nearby in a lineage-network are likely to be more stylistically similar than those from distant lineages...
  • Motordex
    A blog post from Justin Chien, a recent Metis SF graduate, who did a great article on using convolutional neural networks to identify car models, which then has some interesting real-world applications...

  • What I Learned Implementing a Classifier from Scratch in Python
    In order to demystify some of the magic behind machine learning algorithms, I decided to implement a simple machine learning algorithm from scratch. I will not be using a library such as scikit-learn which already has many algorithms implemented. Instead, I’ll be writing all of the code in order to have a working binary classifier algorithm. The goal of this exercise is to understand its inner workings...
  • Python Machine Learning: Scikit-Learn Tutorial
    Today’s scikit-learn tutorial will introduce you to the basics of Python machine learning: step-by-step, it will show you how to use Python and its libraries to explore your data with the help of matplotlib, work with the well-known algorithms KMeans and Support Vector Machines (SVM) to construct models, to fit the data to these models, to predict values and to validate the models that you have build...
