This week, Zephy McKanna sets out to explain Multi-Armed bandits. Here at Wayfair, we are constantly testing new algorithms, product sort orders, marketing, and other messages using epsilon-first Multi-Armed Bandits – also known as A/B tests. We are also employing some more interesting MAB algorithms, like Thompson Sampling, to dynamically balance traffic during tests on low-traffic portions of the site (like holiday décor), as well as for some long-standing dynamic problems like choosing the top N among the ever-changing sales events to send out in emails to default customers.
