Exhaustive and Efficient Constraint Propagation: A Semi-Supervised Learning Perspective and Its Applications
Zhiwu Lu, Horace H. S. Ip, Yuxin Peng
This paper presents a novel pairwise constraint propagation approach by decomposing the challenging constraint propagation problem into a set of independent semi-supervised learnin…
