Click-through rate (CTR) prediction is a critical task in online advertising and marketing. For this problem, existing approaches, with shallow or deep architectures, have three major drawbacks. First, they typically lack persuasive rationales to explain the outcomes of models. Unexplainable predictions recommendations may be difficult validate thus unreliable untrustworthy. In many applications, inappropriate suggestions even bring severe consequences. Second, approaches poor efficiency...
