Nonlinear dimensionality reduction by curvature minimization

2016 23rd International Conference on Pattern Recognition (ICPR), 2016
In this paper, we introduce a nonlinear dimensionality reduction (NLDR) technique that can construct a low-dimensional embedding efficiently and accurately with low embedding distortions. The key idea is to divide NLDR into nonlinearity reduction and linear dimensionality reduction, which simplifies the overall NLDR process.

Data visualization by nonlinear dimensionality reduction

WIREs Data Mining and Knowledge Discovery, 2015
In this overview, commonly used dimensionality reduction techniques for data visualization and their properties are reviewed. Thereby, the focus lies on an intuitive understanding of the underlying mathematical principles rather than detailed algorithmic pipelines. Important mathematical properties of the technologies are summarized in the tabular form.

Linear versus Nonlinear Dimensionality Reduction of High-Dimensional Dynamical Systems

SIAM Journal on Scientific Computing, 2004
The author uses combinations of the K-L decomposition and neural networks to obtain the intrinsic or true dimension of two PDEs, namely, the 1-d K-S equation and the 2-d N-S equations. For the 1-d K-S equation, he investigates one particular dynamical behavior which, in phase space, is represented by a heteroclinic connection.

Supervised Nonlinear Dimensionality Reduction for Visualization and Classification

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2005
When performing visualization and classification, people often confront the problem of dimensionality reduction. Isomap is one of the most promising nonlinear dimensionality reduction techniques. However, when Isomap is applied to real-world data, it shows some limitations, such as being sensitive to noise. In this paper, an improved version of Isomap,

Dimensional Reduction of Nonlinear Delay Systems

2002
Time delays usually give rise to great difficulty in the dynamic analysis of controlled mechanical systems. The difficulty increases so dramatically with an increase of system dimensions that the analytical results for the dynamics of delay systems of high dimensions are considerably few.
