摘要

摘要: 在多标记分类中，某个标记可能只由其自身的某些特有属性决定，这些特定属性称之为类属属性.利用类属属性进行多标记分类，可以有效避免某些无用特征影响构建分类模型的性能.然而类属属性算法仅从标记角度去提取重要特征，而忽略了从特征角度去提取重要标记.事实上，如果能从特征角度提前关注某些标记，更容易获取这些标记的特有属性.基于此，提出了一种新型类属属性学习的多标记分类算法，将从特征层面提取重要标记与从标记层面提取重要特征进行双向联合学习.首先，为了保证模型求解速度与精度都较为合理，采用极限学习机构建学习模型.随后，将弹性网络正则化理论添加到极限学习机损失函数中，使用互信息构建特征标记相关性矩阵作为L\-2正则化项，而L\-1正则化项即提取类属属性.该学习模型改进了类属属性在多标记学习中的不足，通过在标准多标记数据集上与多个先进算法对比，实验结果表明了所提模型的合理性和有效性.

Abstract: In multi-label learning, a label may be determined by its own set of unique features only, which are called label-specific features. Using label-specific features in multi-label classification can effectively avoid some useless features affecting the performance of the constructed classification model. However, existing label-specific features methods only extract important features from the label’s perspective, while ignoring extracting important labels from the feature’s perspective. In fact, it’s easier to extract the unique features for labels by focusing on certain labels from the feature’s perspective. Based on this, a novel label-specific features learning algorithm for multi-label classification is proposed. It combines the label’s important features with the feature’s important labels. Firstly, in order to ensure the efficiency and accuracy of the model, the extreme learning machine is used to construct the joint learning model. Subsequently, the elastic network regularization theory is applied to the extreme learning machine’s loss function, and the mutual information theory is used to construct the correlation matrix of feature-specific labels as the L\-2 regularization term, and the label-specific features are extracted by the L\-1 regularization term. The learning model improves the deficiencies of label-specific features and the adaptability of the extreme learning machine in multi-label learning. Compared with several state-of-the-art algorithms on several benchmark multi-label datasets, the experimental results show the rationality and effectiveness of the proposed model.
