Architecting a Machine Learning System for Risk -- Airbnb Engineering & Data Science

At Airbnb, we want to build the world's most trusted community. Guests trust Airbnb to connect them with world-class hosts for unique and memorable travel experiences. Airbnb hosts trust that guests will treat their home with the same care and respect that they would their own. The Airbnb review system helps users find community members who earn this trust through positive interactions with others, and the ecosystem as a whole prospers. The overwhelming majority of web users act in good faith, but unfortunately, there exists a small number of bad actors who attempt to profit by defrauding websites and their communities.
