Predicting New Sort Performance When Data is Sparse / Missing
December 1, 2020
Goal At Wayfair, we want to predict the performance of new sorting algorithms before we launch them. Why? Sorting algorithms make money! Think about it: what’s the main difference between scrolling randomly through our ~18 million products ve...
TopShelf: How to Arrange a Page of Products, Not Just Rank Them in a List
May 5, 2020
Many approaches to ranking a list of products or search results are based on assigning a score to each item and sorting in descending order—in other words, greedy sorting approaches. In e-commerce, predictive models place the product that the custo...

How We Work
Here at Wayfair Data Science, our core values are rigor, curiosity, and fun.
Rigor
From search engines to shipping logistics, Data Science is central to everything we do at Wayfair. As such, it's vital that we get things right. Our thorough in-house testing platform, rolling code deployments, and iterative research-style approach ensure that our work is thorough, precise, and driving the business.
Curiosity
Wayfair’s abundance of data means that there are always new problems to be solved. As such, team members are empowered to explore our data to develop new, high impact ideas and then develop experiments to probe those questions. We also partner with professors and students from Harvard, MIT, Stanford, Columbia, and Cornell to bring the most advanced ML technologies into production.
Fun
No one is too busy to brainstorm or answer a question, and code is shared as freely as the snacks in the kitchen. We like doing things together, whether that means collaborating on a pricing experiment or going rockclimbing, kayaking, painting, or visiting a distillery with our coworkers during our monthly pod outings.
