Hyperspectral data potentially contain more information than multispectral data because of their higher spectral resolution. However, the stochastic data analysis approaches that have been successfully applied to multispectral data are not as effective for hyperspectral data as well. Various investigations indicate that the key problem that causes poor performance in the stochastic approaches t...
متن کاملA Note on Projection Pursuit
I provide a historic review of the forward and backward projection pursuit algorithms, previously thought to be equivalent, and point out an important difference between the two. In doing so, I correct a small error in the original exploratory projection pursuit paper (Friedman 1987). The implication of the difference is briefly discussed in the context of an application in which projection pur...

This article provides a historic review of the forward and backward projection pursuit algorithms, previously thought to be equivalent, and points out an important difference between the two. In doing so, a small error in the original exploratory projection pursuit article by Friedman [J. Amer. Statist. Assoc. 82 (1987) 249–266] is corrected. The implication of the difference is briefly discuss...
متن کاملEfficient Parametric Projection Pursuit Density Estimation
Product models of low dimensional experts are a powerful way to avoid the curse of dimensionality. We present the "under complete product of experts" (UPoE), where each expert models a one dimensional pro jection of the data. The UPoE may be inter preted as a parametric probabilistic model for projection pursuit. Its ML learning rules are identical to the approximate learning rules proposed ...
متن کاملProjection Pursuit Multivariate Transform
Transforming complex multivariate geological data to be multivariate Gaussian is an important and challenging problem in geostatistics. A variety of transforms are available to accomplish this goal, but may struggle with data sets of high dimensional and sample sizes. Projection Pursuit Density Estimation (PPDE) is a well-established non-parametric method for estimating the joint PDF of multiva...
متن کاملGaussianization
High dimensional data modeling is difficult mainly because the so-called "curse of dimensionality". We propose a technique called "Gaussianization" for high dimensional density estimation, which alleviates the curse of dimensionality by exploiting the independence structures in the data. Gaussianization is motivated from recent developments in the statistics literature: projection pursuit, inde...
