一种基于平滑表示模型的多视图简化算法

A Multi-view Dimensionality Reduction Algorithm Based on Smooth Representation Model

Haohao Li, Huibing Wang

摘要:

在过去的几十年里,我们已经看到了一个大家族的算法,这些算法被设计为提供不同的解决方案的降维(DR)的问题。DR是从高维数据中挖掘重要信息的重要工具,它将数据映射到低维子空间。此外,由于各种高维数据的多样性,可以利用多视图特征来提高学习性能。然而,许多DR方法无法集成多个视图。虽然不同视图的特征提取方式不同,但它们都是用来描述同一样本的,这意味着它们是高度相关的。因此,如何利用多视点特征的一致性和互补性来学习高维特征的子空间是当前的重要课题。本文提出了一种有效的多视图降维算法--多视图平滑保持投影算法。首先,我们构造了一个单视图DR方法称为平滑保持投影平滑表示模型的基础上。该方法的目的是为高维数据找到一个子空间,在该子空间中尽可能多地保留光滑的重构权重。然后,我们将其扩展到多视图版本,其中我们利用希尔伯特-施密特独立准则来共同学习所有视图的一个公共子空间。在多视图数据集上的大量实验表明了该方法的良好性能。

英文摘要:

Over the past few decades, we have witnessed a large family of algorithms that have been designed to provide different solutions to the problem of dimensionality reduction (DR). The DR is an essential tool to excavate the important information from the high-dimensional data by mapping the data to a low-dimensional subspace. Furthermore, for the diversity of varied high-dimensional data, the multi-view features can be utilized for improving the learning performance. However, many DR methods fail to integrating multiple views. Although the features from different views are extracted by different manners, they are utilized to describe the same sample, which implies that they are highly related. Therefore, how to learn the subspace for high-dimensional features by utilizing the consistency and complementary properties of multi-view features is important in the present. In this paper, we propose an effective multi-view dimensionality reduction algorithm named Multi-view Smooth Preserve Projection. Firstly, we construct a single view DR method named Smooth Preserve Projection based on the Smooth Representation model. The proposed method aims to find a subspace for the high-dimensional data, in which the smooth reconstructive weights are preserved as much as possible. Then, we extend it to a multi-view version in which we exploits Hilbert-Schmidt Independence Criterion to jointly learn one common subspace for all views. A plenty of experiments on multi-view datasets show the excellent performance of the proposed method.
