中文简介:
多实例学习(MIL)处理歧义下的学习,其中要分类的模式由实例包描述。人们对MIL算法的设计和使用越来越感兴趣,因为它提供了解决多种模式识别问题的自然框架。在本文中,我们从通过实例选择将问题转变为标准的监督学习问题的角度来解决MIL。所提出的方法的新颖性在于它的选择策略,可以在正向和负向训练包中识别最具代表性的示例,该方法基于有效的成对聚类算法(称为显性集)。在标准基准数据集和多类图像分类问题上的实验结果表明,所提出的方法不仅与最新的MIL算法具有很高的竞争力,而且对异常值和噪声也非常健壮。
课程简介: Multiple-instance learning (MIL) deals with learning under ambiguity, in which patterns to be classified are described by bags of instances. There has been a growing interest in the design and use of MIL algorithms as it provides a natural framework to solve a wide variety of pattern recognition problems. In this paper, we address MIL from a view that transforms the problem into a standard supervised learning problem via instance selection. The novelty of the proposed approach comes from its selection strategy to identify the most representative examples in the positive and negative training bags, which is based on an effective pairwise clustering algorithm referred to as dominant sets. Experimental results on both standard benchmark data sets and on multi-class image classification problems show that the proposed approach is not only highly competitive with state-of-the-art MIL algorithms but also very robust to outliers and noise.
