Dimensionality Reduction There are many sources of data that can be viewed as a large matrix. We saw in Chapter 5 how the Web can be represented as a transition matrix. In Chapter 9, the utility matrix was a point of focus. And in Chapter 10 we examined matrices that represent social networks.

Abstract. In this manuscript, we will address the problem of dimension reduction for data modelled by an exponential family distribution, with a particular focus on text data mode.

In this thesis we demonstrate how to reduce the dimension of a certain class of dynamical systems by construction of k-dimensional submanifolds using the so-called graph transform. The method is suitable for a specific class of problems with spectral gaps, these are often observed. In particular the method is applied to a mechanical system.

Below is a summary of some of the important algorithms from the history of manifold learning and nonlinear dimensionality reduction (NLDR). Many of these non-linear dimensionality reduction methods are related to the linear methods listed below.Non-linear methods can be broadly classified into two groups: those that provide a mapping (either from the high-dimensional space to the low.

The concept of influence function was originally introduced by Hampel (1968) in his PhD thesis as a tool to study robustness of an estimator, and has been used by Prendergast (2005, 2007) in the dimension reduction framework to analyse the statistical properties of various inverse regression methods.

In this thesis apparently unrelated topics are addressed: dimensionality reduction, meshfree analysis of thin-shells, nonlinear model reduction of mechanical systems, quantitative analysis of a motility mode exhibited by the Euglenids (a family of protists), and the automatic detection of collective variables from biomolecular ensembles.

Analysis (PCA) is the standard tool for dimension reduction. For autocorrelated processes, however, PCA fails to take into account the autocorrelation information. Thus, it is doubtful that PCA is the best choice. A two-step dimension reduction procedure is devised for multivariate time series. Comparisons based on both simulated examples and.

Therefore, in this thesis, we aim to explore the portfolio-selection problem from an information-theoretic angle, accounting for higher moments. We review the relevant literature and mathematical.The goal of this PhD thesis is to tackle this problem. Numerous dimension reduction techniques can be used, depending on the context: Principal Component Analysis (PCA) in the unsupervised case, discriminant analysis in the case of supervised classification, Sliced Inverse Regression in the regression context are some of the most standard and popular algorithms.In statistics, machine learning, and information theory, dimensionality reduction or dimension reduction is the process of reducing the number of random variables under consideration by obtaining a set of principal variables. Approaches can be divided into feature selection and feature extraction.


Supervised linear dimension reduction (SLDR) is one of the most effective methods for complexity reduction, which has been widely applied in pattern recognition, computer vision, information retrieval, and multimedia data processing. This thesis explores SLDR by enriching the theory of existing methods and by proposing new methods.Statistics Department Baker Hall 132 Pittsburgh, PA 15213 Phone: (412) 268-2717 Fax: (412) 268-7828.
