摘要:

本文介绍了一种新的角度在机器学习中的错误,并提出逆特征学习(IFL)作为一种表示学习方法,学习一组高层次的功能的基础上表示的错误分类或聚类的目的。所提出的关于错误表示的观点从根本上不同于当前的学习方法,在分类方法中,他们将错误解释为真实标签和预测标签之间的差异的函数,或者在聚类方法中,使用聚类目标函数,如紧凑性。逆特征学习方法基于深度聚类方法来操作,以获得误差作为特征的表示的定性形式。建议IFL方法的性能进行评估,通过应用学习功能与原始功能,或只是使用学习功能在不同的分类和聚类技术的几个数据集。实验结果表明,该方法在分类,特别是聚类方面取得了良好的效果。在分类中,所提出的特征与主要特征一起改善了大多数分类方法在几个流行数据集上的结果。在聚类中,不同的聚类方法的性能在不同的数据集上有很大的提高。有一些有趣的结果,显示一些功能的错误捕获的主要功能的高度信息方面的表示。我们希望这篇论文能有助于错误表示学习在不同特征学习领域的应用。

英文摘要:

This paper introduces a novel perspective about error in machine learning and proposes inverse feature learning (IFL) as a representation learning approach that learns a set of high-level features based on the representation of error for classification or clustering purposes. The proposed perspective about error representation is fundamentally different from current learning methods, where in classification approaches they interpret the error as a function of the differences between the true labels and the predicted ones or in clustering approaches, in which the clustering objective functions such as compactness are used. Inverse feature learning method operates based on a deep clustering approach to obtain a qualitative form of the representation of error as features. The performance of the proposed IFL method is evaluated by applying the learned features along with the original features, or just using the learned features in different classification and clustering techniques for several data sets. The experimental results show that the proposed method leads to promising results in classification and especially in clustering. In classification, the proposed features along with the primary features improve the results of most of the classification methods on several popular data sets. In clustering, the performance of different clustering methods is considerably improved on different data sets. There are interesting results that show some few features of the representation of error capture highly informative aspects of primary features. We hope this paper helps to utilize the error representation learning in different feature learning domains.
