Wow! We are so honored to be ranked #13 on Fast Company’s Most Innovative Companies List. And, we’re thrilled to be ranked #1 on Fast Company’s Data Science List.
It's really gratifying to see Data Science becoming a primary means of strategic differentiation ...
This past December marked three years since I joined Stitch Fix Engineering. In that short time, I’ve witnessed the bulk of the growth that we’ve experienced as a company since our founding. For example, in December 2014 there were roughly 10 engineers and now we number nearly 100. It was a time when those of us at our SF headquarters used to be able to sit around a small conference room table for our all hands meetings. Similarly, we needed just a slightly larger table when our remote engineers (roughly 50% of our team) came to SF for a week during our once-quarterly Engineering summits.
On the Stitch Fix Algorithms team, we’ve always been in awe of what professional stylists are able to do, especially when it comes to knowing a customer’s size on sight. It’s a magical experience to walk into a suit shop, have the professional shopping assistant look you over and without taking a measurement say, “you’re probably a 38, let’s try this one,” and pull out a perfect-fitting jacket. While this sort of experience has been impossible with traditional eCommerce, at Stitch Fix we’re making it a reality.
The lights are dimmed, bingo cards are dealt, and the scent of popcorn (well, melted butter..) spreads through the corridors... It’s time for usability movie night, and everyone’s invited!
I’ve been lax in updating the “Patterns of Service-oriented Architecture” series, so here’s a new one on a time-honored and critical technique: Database Transactions. This is a powerful feature of most SQL databases that allows you to apply a series of changes to the database in an “all or nothing” type of approach.
Recently Increment published an issue about what it is like being a developer at a number of great companies like Fastly, Lyft, and DigitalOcean. We thought it would be fun to create a blog post answering the same questions about what it’s like at Stitch Fix.
Counting and tensor decompositions are elegant and straightforward techniques. But these methods are grossly underepresented in business contexts. In this post we factorized an example made up of word skipgrams occurring within documents to arrive at word and document vectors simultaneously. This kind of analysis is effective, simple, and yields powerful concepts.
When I started playing with word2vec four years ago I needed (and luckily had) tons of supercomputer time. But because of advances in our understanding of word2vec, computing word vectors now takes fifteen minutes on a single run-of-the-mill computer with standard numerical libraries1. Word vectors are awesome but you don't need a neural network -- and definitely don't need deep learning -- to find them. So if you're using word vectors and aren't gunning for state of the art or a paper publication then stop using word2vec.
Today is the start of the 2017-2018 NBA Season. Basketball statistics have become a rich and intriguing domain of study, bringing new insights and advantages to the teams that embrace such empiricism. Of course, the framing and analytic techniques used to study basketball are generalizations - they also give intuition to problems in business or other domains (and vice versa). So, for all the basketball statistics enthusiasts out there, as well as those that are looking for inspirations for their own analytic challenges, we thought we’d share a compendium of our past basketball-related posts.
At Stitch Fix we certainly have enough data that it qualifies as Big, but since we collect the data ourselves we focus on making it as Rich as possible.
