Pairwise constraint propagation aims to increase the number of accurate pairwise constraints through propagation learning on the basis of the initial given exact pairwise constraints to provide additional supervision information for the machine learning task. However, inaccurate pairwise constraints occasionally exist in real scenes. Therefore, one problem to be solved is the use of these inaccurate pairwise constraints to enhance pairwise constraint propagation. A propagation method of uncertain pairwise constraints is proposed in this paper to solve this problem. The main idea is to use two matrices to represent the possibility of must-links and cannot-links. A confrontation between the two possibilities and a confrontation relationship between two kinds of pairwise constraints exist. The combination of two types of confrontation forms a double adversarial structure, which acts on the propagation process of must-links and cannot-links; therefore, the adversarial intensity between them is minimized in the competition. This method is called uncertain pairwise constraint propagation. Experimental results on multiple datasets show that the propagation effect of uncertain pairwise constraints does not exceed but is similar to the ideal propagation effect, which enhances the practical applicability and ensures the propagation accuracy completely.
