Ad Click Prediction: a View from the TrenchesPublished August 2013Paper linkAbstractIntroductionBrief System OverviewProblem StatementFor any given a query, ad, and associated interaction and metadata represented as a real feature vector \(\textbf{x}\in\mathbb{R}^d\), provide an estimate of the probability \(\mathbb{P}(\text{click}(\textbf{x}))\)that the user making the query will click on the ad. Solving this problem has beneficial implications for ad auction pricing in Google’s online adver... Read More
