Topological local principal component analysis

In help of the Kohonen’s self-organizing maps we present a topological local principal component analysis model which is capable of exploiting both the global topological structure and each local cluster structure. A newly proposed self-organizing strategy that can enhance the learning speed is introduced to train the model. c © 2003 Elsevier B.V. All rights reserved.

Local functional principal component analysis

Covariance operators of random functions are crucial tools to study the way random elements concentrate over their support. The principal component analysis of a random function X is well-known from a theoretical viewpoint and extensively used in practical situations. In this work we focus on local covariance operators. They provide some pieces of information about the distribution of X around ...

Improving Sparse Representation-Based Classification Using Local Principal Component Analysis

Sparse representation-based classification (SRC), proposed by Wright et al., seeks the sparsest decomposition of a test sample over the dictionary of training samples, with classification to the most-contributing class. Because it assumes test samples can be written as linear combinations of their same-class training samples, the success of SRC depends on the size and representativeness of the ...

Principal Component Analysis Image Denoising Using Local Pixel Grouping

In recent years various image processing techniques have been developed. These include medical, satellite, space, transmission and radar etc. But noise in image effect all applications. So it is necessary to remove noise from image. There are various methods and techniques to remove noise from images. Wavelet transform (WT) is effective in noise removal but it has some limitations that are over...
