Most of the existing multilabel classifiers attempt to exhaustively explore dependency between correlated labels. It increases the risk of involving unnecessary label dependencies, which are detrimental to classification performance. Actually, not all the label correlations are indispensable to multilabel mode l. Negligible or fragile label correlations cannot be generalized well to the testing data, especially if there exists label correlation discrepancy between training and testing sets. To minimize such negative effect in the multilabel model, we propose to learn a sparse structure of label dependency. The underlying philosophy is that as long as the multilabel dependency cannot be well explained, the principle of parsimony should be applied to the modeling process of the label correlations. The obtained sparse label dependency structure discards the outlying correlations between labels, which makes the learned model more unrealizable to future samples. Experiments on real world data sets show the competitive results compared with existing algorithms.
- 2. Existing method: Most of existing multi- label classifiers assume that the labels are ubiquitously correlated with each other with densely correlative dependency. However, it does not hold since there exist labels with negligible or quite weak correlations among them. For example, it is intuitive that “bird” and “train” have no obvious correlations between them. Incorporating such outlying label correlations can increase the risk of imposing incorrect correlative constraints between labels that are not generalizable to testing samples. From the perspective of modeling, it unnecessarily increases the complexity of the multi- label model, which makes the label correlations in the

Proposed method: Supervised learning (SL), consists of training and prediction phases, which requires a batch of training examples annotated by a set of semantic labels to establish a learner of the satisfactory generalization capability. To work toward the goal, various methods for multi- label classification have been proposed according to different problem settings. Chen et al. proposed a supervised nonnegative matrix factorization (NMF) approach for both image classification and annotation with the aid of label information, in which two supervised nonnegative matrix factorizations are combined together to identify the latent image bases and represent the training images in the bases space. Hypergraph spectral learning is utilized in and for multi- label classification, where a hypergraph is constructed to exploit the correlation information among different labels. Han et al. proposed a multi- task sparse discriminate analysis approach that formulates multi- label prediction as a quadratic optimization problem. Structured visual feature selection and the implementation of hierarchical correlated structures among multiple tags are exp lored together in to boost the performance of image annotation.
