- Abstract:
-
Label distribution learning (LDL) is a novel learning paradigm for solving labeling polysemy. Most existing LDL methods are designed based on complete data information; however, because of high labeling costs and the limitation of labelers’ level, complete labeling data information is difficult to obtain, which leads to performance degradation in traditional LDL algorithms. In this paper, we propose a novel weakly supervised LDL by maintaining a local label ranking (WSLDL-MLLR) algorithm. We improve algorithm performance under incomplete data labeling by maintaining relative relationships between the not-yet-missing labels and using label correlation to recover missing labels. Extensive experiments conducted on 14 datasets verified the effectiveness of the algorithm.
