Automatic image annotation is widely considered to be an important yet open problem due to the well-known semantic gap. Recent works show that nearest-neighbor-based annotation approaches are simple and effective. In this paper we use a modified keywords transfer mechanism base on image-keyword unidirectional graph to derive a great annotator. The unidirectional graph describes the relationship...

We develop a tool akin to the revelation principle for dynamic mechanism‐selection games in which designer can only commit short‐term mechanisms. identify canonical class of mechanisms rich enough replicate outcomes any equilibrium game between an uninformed and privately informed agent. A cornerstone our methodology is idea that mechanism should encode not rules determine allocation, but also ...
