Abstract

The invention relates to the field of label propagation, and discloses a label propagation method for a weak label data set, which comprises the following steps: constructing a label propagation graph which comprises a label sample and a label-free sample, and the label sample and the label-free sample are connected through an undirected edge; obtaining category labels and labeled samples in the label propagation graph to construct a probability transfer matrix and a labeling matrix; when the labeled sample receives label information spread from an adjacent sample, filtering the label information to complement the label information of the labeled sample; spreading unmarked data by using the complemented label information; whether the label matrix converges is judged, if yes, label propagation is completed, an original label propagation algorithm is improved by adopting a feedback thought, missing label information of weak label data is filled, and the label distribution accuracy is improved.

Description

technical field [0001] This application relates to the field of label propagation, in particular to a label propagation method for weak label datasets. Background technique [0002] Studies have shown that in multi-label data, incomplete labels and label noise are very common. For example, for image samples in scene classification tasks, the labels are prone to noise and missing labels, such as a small number of labels describing useless information, and some labels being unlabeled. Usually, "weak label dataset" refers to a multi-label dataset with features such as incomplete labels and certain noise labels. In real-world large-scale data collection and manual labeling, weak labels are unavoidable. The weak label nature of the dataset reduces the algorithm performance of multi-label learning to a certain extent, and also affects its application in real life. [0003] Therefore, how to improve the accuracy of label assignment when weak label data is missing has become an u...
