Abstract: A new method for performing a nonlinear form of Principal Component Analysis is proposed. By the use of integral operator kernel functions, one can efficiently compute principal components in highdimensional feature spaces, related to input space by some nonlinear map; for instance the space of all possible d-pixel products in images. We give the derivation of the method and present experimental results on polynomial feature extraction for pattern recognition.

Using FCMC, FVS, and PCA techniques for feature extraction of multispectral images
TL;DR: A new nonlinear approach based on a combination of the fuzzy c-means clustering, feature vector selection and principal component analysis is proposed to extract features of multispectral images when a very large number of samples need to be processed.

An efficient kernel matrix evaluation measure
Canh Hao Nguyen,Tu Bao Ho +1 more
TL;DR: This work proposes an efficient surrogate measure to evaluate the goodness of a kernel matrix based on the data distributions of classes in the feature space that not only overcomes the limitations of KTA but also possesses other properties like invariance, efficiency and an error bound guarantee.

Geometry- and Accuracy-Preserving Random Forest Proximities
TL;DR: This paper proves that the proximity-weighted sum (regression) or majority vote (classification) using RF-GAP exactly match the out-of-bag random forest prediction, thus capturing the data geometry learned by the random forest.

Application of the Karhunen-Loeve procedure for the characterization of human faces
Michael Kirby,Lawrence Sirovich +1 more
TL;DR: The use of natural symmetries (mirror images) in a well-defined family of patterns (human faces) is discussed within the framework of the Karhunen-Loeve expansion, which results in an extension of the data and imposes even and odd symmetry on the eigenfunctions of the covariance matrix.
