论文摘要
这项工作为聚类提供了无监督的深入判别分析。该方法基于深层神经网络,旨在最大程度地减少群集内差异,并以无监督的方式最大化群体间差异。该方法能够将数据投射到具有紧凑和不同分布模式的非线性低维潜在空间中,以便可以有效地识别数据簇。我们进一步提供了该方法的扩展,以便可以有效利用可用的图形信息来提高聚类性能。带有或没有图形信息的图像和非图像数据的广泛数值结果证明了所提出的方法的有效性。
This work presents an unsupervised deep discriminant analysis for clustering. The method is based on deep neural networks and aims to minimize the intra-cluster discrepancy and maximize the inter-cluster discrepancy in an unsupervised manner. The method is able to project the data into a nonlinear low-dimensional latent space with compact and distinct distribution patterns such that the data clusters can be effectively identified. We further provide an extension of the method such that available graph information can be effectively exploited to improve the clustering performance. Extensive numerical results on image and non-image data with or without graph information demonstrate the effectiveness of the proposed methods.
