摘要:

近年来,标签分布学习(LabelDistribution Learning,LDL)在机器学习中引起了广泛的关注,LDL模型是从标签实例中学习得到的。与单标签和多标签标注不同,标签分布通过多个不同强度的标签来描述实例,并适应更一般的场景。由于大多数现有的机器学习数据集只提供逻辑标签,标签分布在许多现实世界的应用中是不可用的。为了解决这个问题,我们提出了两种新的标签增强方法,即,标签增强与样本相关性(LESC)和广义标签增强与样本相关性(gLESC)。更具体地说,LESC采用特征空间中样本的低秩表示,gLESC利用张量多秩最小化来进一步研究特征空间和标签空间中的样本相关性。利用样本间的相关性,本文提出的方法可以提高标签增强的性能。在14个基准数据集上的实验证明了该方法的有效性和优越性。

英文摘要:

Recently, label distribution learning (LDL) has drawn much attention in machine learning, where LDL model is learned from labelel instances. Different from single-label and multi-label annotations, label distributions describe the instance by multiple labels with different intensities and accommodate to more general scenes. Since most existing machine learning datasets merely provide logical labels, label distributions are unavailable in many real-world applications. To handle this problem, we propose two novel label enhancement methods, i.e., Label Enhancement with Sample Correlations (LESC) and generalized Label Enhancement with Sample Correlations (gLESC). More specifically, LESC employs a low-rank representation of samples in the feature space, and gLESC leverages a tensor multi-rank minimization to further investigate the sample correlations in both the feature space and label space. Benefitting from the sample correlations, the proposed methods can boost the performance of label enhancement. Extensive experiments on 14 benchmark datasets demonstrate the effectiveness and superiority of our methods.
