New paint colors invented by neural network
So if you’ve ever picked out paint, you know that every infinitesimally different shade of blue, beige, and gray has its own descriptive, attractive name. Tuscan sunrise, blushing pear, Tradewind, etc… There are in fact people who invent these names for a living. But given that the human eye can see millions of distinct colors, sooner or later we’re going to run out of good names. Can AI help?...
Predicting Lung Cancer: Solution Write-up
The Data Science Bowl is an annual data science competition hosted by Kaggle. In this year’s edition the goal was to detect lung cancer based on CT scans of the chest from people diagnosed with cancer within a year. To tackle this challenge, we formed a mixed team of machine learning savvy people of which none had specific knowledge about medical image analysis or cancer prediction. Hence, the competition was both a nobel challenge and a good learning experience for us. The competition just finished and our team Deep Breath finished 9th! In this post, we explain our approach...

A Day in the Life of Americans
So again I looked at microdata from the American Time Use Survey from 2014, which asked thousands of people what they did during a 24-hour period. I used the data to simulate a single day for 1,000 Americans representative of the population — to the minute. More specifically, I tabulated transition probabilities for one activity to the other, such as from work to traveling, for every minute of the day. That provided 1,440 transition matrices, which let me model a day as a time-varying Markov chain. The simulations below come from this model, and it’s kind of mesmerizing...
Using Machine Learning to Explore Neural Network Architecture
To make this process of designing machine learning models much more accessible, we’ve been exploring ways to automate the design of machine learning models. Among many algorithms we’ve studied, evolutionary algorithms  and reinforcement learning algorithms  have shown great promise. But in this blog post, we’ll focus on our reinforcement learning approach and the early results we’ve gotten so far...
First In-Depth Look at Google's New Second Generation TPU
This morning at the Google’s I/O event, the company stole Nvidia’s recent Volta GPU thunder by releasing details about its second-generation tensor processing unit (TPU), which will manage both training and inference in a rather staggering 180 teraflops system board, complete with custom network to lash several together into “TPU pods” that can deliver Top 500-class supercomputing might at up to 11.5 petaflops of peak performance...
Automated Machine Learning (AML) —
A Paradigm Shift That Accelerates Data Scientist Productivity @ Airbnb
The scope of AML is ambitious, however, is it really effective? The answer is it depends on how you use it. Our view is that it is difficult to perform wholesale replacement of a data scientist with an AML framework, because most machine learning problems require domain knowledge and human judgement to set up correctly. Also, we have found AML tools to be most useful for regression and classification problems involving tabular datasets, however the state of this area is quickly advancing. In summary, we believe that in certain cases AML can vastly increase a data scientist’s productivity, often by an order of magnitude...
Who Owns England?
Who owns land is one of England's most closely-guarded secrets. This map is a first attempt to display major landowners in England, combining public data with Freedom of Information requests...
