面向标签可变性的可拓分类方法

    Extension Classification Method for Label Variability

    • 摘要: 传统分类方法通常假设训练样本的类别标签是静态且确定的,忽略了现实场景中样本标签可能随条件变化而发生转变的动态性特征。针对这一问题,本文提出了一种新的学习问题设定——标签可变性的可拓分类问题,在训练数据中同时标注样本的类别标签与标签可变性状态,用以刻画样本在变化机制作用下的类别转变潜力。基于此设定,设计了多标签学习框架,构建了基于支持向量机的可变标签可拓分类算法,实现类别判别与标签可变性预测的协同优化。实验部分在合成数据集与真实数据集上验证了所提算法的有效性。本文工作为复杂系统中标签动态性学习问题提供了一种新的建模思路,具有较好的应用前景。

       

      Abstract: Traditional classification algorithms typically assume that the labels of training samples are static and deterministic, ignoring the dynamic characteristics of sample labels that may change with conditions in real-world scenarios. In response to this issue, this paper proposes a new learning problem setting—the Extended Classification Problem, which simultaneously gives the class labels and label variability states of samples in the training data, which to characterize the class transition potential of samples under the influence of change mechanisms. Based on this setting, a multi-label learning framework was designed, an extension classification algorithm for label variability using support vector machine was constructed, to achieve collaborative optimization of category discrimination and label variability prediction. The experimental section validated the effectiveness of the proposed algorithm on both synthetic and real datasets. This paper provides a new modeling approach for label dynamic learning problems, which has good application prospects.
