Oblique Projection Matching Pursuit

Mobile Networks and Applications, 2016
Recent theory of compressed sensing (CS) tells us that sparse signals can be reconstructed from a small number of random samples. In reconstruction of sparse signals, greedy algorithms, such as the orthogonal matching pursuit (OMP), have been shown to be computationally efficient.

Projection pursuit

WIREs Computational Statistics, 2009
AbstractProjection pursuit is a technique for finding highly informative low‐dimensional projections of multivariate data for visual inspection by an analyst. When data of dimension m are reduced to dimension p (where typically p = 2 is the most useful for viewing by scatter plots), the method consists of defining a measure of information content in ...

Automatic Induction of Projection Pursuit Indices

IEEE Transactions on Neural Networks, 2010
Projection techniques are frequently used as the principal means for the implementation of feature extraction and dimensionality reduction for machine learning applications. A well established and broad class of such projection techniques is the projection pursuit (PP).

Exploratory Projection Pursuit

1995
“Projection Pursuit” (PP) stands for a class of exploratory projection techniques. This class contains methods designed for analyzing high dimensional data using low-dimensional projections. The main idea is to describe “interesting” projections by maximizing an objective function or projection pursuit index.

Projection pursuit learning

IJCNN-91-Seattle International Joint Conference on Neural Networks, 2002
A learning model based on a nonparametric statistical technique, projection pursuit regression, is studied. Projection pursuit is a nonparametric statistical technique to find interesting low-dimensional projections of high-dimensional data sets. Projection pursuit regression approximates a function of q variables by a sum of nonlinear functions of ...

Combining Exploratory Projection Pursuit and Projection Pursuit Regression with Application to Neural Networks

Neural Computation, 1993
We present a novel classification and regression method that combines exploratory projection pursuit (unsupervised training) with projection pursuit regression (supervised training), to yield a new family of cost/complexity penalty terms. Some improved generalization properties are demonstrated on real-world problems.

Fuzzy projection pursuits

Fuzzy Sets and Systems, 1988
Two objections to the ``classical'' approach in projection pursuit have inspired the authors to translate the classical projection pursuit technology for a fuzzy-reasoning approach. These are: (i) The classical approach takes into account all axes (all components of data) with the same weights not assuming different importance, precision etc., (ii) the

Projection pursuit by involution

Communications in Statistics - Simulation and Computation, 1997
A novel projection pursuit method based on projecting the data onto itself is proposed. Using a number of real datasets it is shown how to obtain interesting one and two-dimensional projections using only O(n) evaluations of a one-dimensional projection index.
