People say that security is hard and that’s exactly why we have a dedicated security team here at Yelp! We place tremendous importance on securing our environment, our employees and the millions of visitors who trust Yelp every month. Information Security is not a solo endeavor.

This is why we are officially sponsoring Security BSides Las Vegas 2014! BSides is a...

Given a feature, we want to find the optimal configuration values for the constants and hyperparameters of the feature as...
