New transfer classification method optimizes source-target risk conversion

This paper introduces a novel approach to transfer classification by analyzing how the training problem of a source dataset influences the accuracy and value for a target dataset. For binary classification, it derives precise target excess hinge-risk bounds based on density-weighted local votes. The research also establishes minimax classification rates for transferable strength and tilt, differentiating between source sampling uncertainty and relation uncertainty. Furthermore, it demonstrates that the minimax risk can be significantly higher when the target sample size is smaller than the source sample size, highlighting the importance of the source's training problem and its relation to the target.
