视觉数据分类旨在为每个类确定唯一的标签,是机器学习社区中越来越重要的问题。近年来,度量学习在分类中的应用受到越来越多的关注,这已被证明是一种很好的方法,以获得有前途的性能。然而,由于训练样本的有限性和数据的复杂分布,这些算法中的绝大多数通常不能很好地执行。这促使我们开发了一种新的局部自适应最大间隔度量学习(LAM3L)算法,以最大限度地分离相似和不相似的类,基于最大间隔度量学习前后的距离之间的变化。在两个广泛使用的UCI数据集和一个真实的高光谱数据集上的实验结果表明,该方法优于现有的度量学习方法。
Visual data classification, which is aimed at determining a unique label for each class, is an increasingly important issue in the machine learning community. In recent years, increasing attention has been paid to the application of metric learning for classification, which has been proven to be a good way to obtain a promising performance. However, as a result of the limited training samples and data with complex distributions, the vast majority of these algorithms usually fail to perform well. This has motivated us to develop a novel locally adaptive maximum margin metric learning (LAM3L) algorithm in order to maximally separate similar and dissimilar classes, based on the changes between the distances before and after the maximum margin metric learning. The experimental results on two widely used UCI datasets and a real hyperspectral dataset demonstrate that the proposed method outperforms the state-of-the-art metric learning methods.
