摘要:

聚类在许多现实世界的应用中扮演着重要的角色,例如市场研究、模式识别、数据分析和图像处理。然而,由于输入特征值的高维性,被馈送到聚类算法的数据通常包含噪声,从而可能导致不准确的聚类结果。虽然传统的降维和特征选择算法可以用来解决这个问题,这些算法中使用的简单的启发式规则是基于一些特定的假设。当这些假设不成立时,这些算法可能就不起作用了。在本文中,我们提出了DAC,基于深度自动编码器的聚类,这是一个通用的数据驱动框架,可以使用深度神经元网络学习聚类表示。实验结果表明,该方法可以有效地提高K-Means聚类算法在各种类型数据集上的性能。

英文摘要:

Clustering performs an essential role in many real world applications, such as market research, pattern recognition, data analysis, and image processing. However, due to the high dimensionality of the input feature values, the data being fed to clustering algorithms usually contains noise and thus could lead to in-accurate clustering results. While traditional dimension reduction and feature selection algorithms could be used to address this problem, the simple heuristic rules used in those algorithms are based on some particular assumptions. When those assumptions does not hold, these algorithms then might not work. In this paper, we propose DAC, Deep Autoencoder-based Clustering, a generalized data-driven framework to learn clustering representations using deep neuron networks. Experiment results show that our approach could effectively boost performance of the K-Means clustering algorithm on a variety types of datasets.
