Deep CNN with Graph Laplacian Regularization for Multi-label Image Annotation

摘要

To compensate for incomplete or imprecise tags in training samples, this paper proposes a learning algorithm for the convolutional neural network (CNN) for multi-label image annotation by introducing co-occurrence dependency between tags as a graph Laplacian regularization term. To exploit the co-occurrence dependency, we apply Hayashi's quantification method-type III to the tags in the training samples and use the distances between the acquired representative vectors to define the weights for graph Laplacian regularization. By introducing this regularization term, the possibility of co-occurrence between tags with high co-occurrence frequency can be increased. To confirm the effectiveness of the proposed algorithm, we have done experiments using Corel5k's dataset for multi-label image annotation.
