A recursive dimension-reduction method for high ...

The poor performance of the results of GSA and conventional ASM indicate that too much information is lost in the coarse dimension reduction procedure. The results of the surrogate model methods (kriging, ANN, SVM) show that the lack of sampling in the failure domains may severely undermine the validity of the surrogate model methods for rare ...

dimensionality of the data would otherwise lead to burden-some computations. Our application areas are the process-ing of both noisy and noiseless images, and information re-trieval in text documents.

Dimensionality Reduction for Dynamical Systems with ...

Dimensionality reduction methods allow for the study of high-dimensional systems by producing low-dimensional descriptions that preserve the relevant structure and features of interest. For dynamical systems, attractors are particularly important ex- amples of such features, as they govern the long-term dynamics of the system, and are typically low-dimensional even if the state space is high ...

Dec 18, 2007 · Therefore, these conventional methods may require a preprocessing step, namely dimension reduction. Dimension reduction can be seen as a transformation from a high order dimension to a low order dimension in order to conquer the so- called "curse of the dimensionality," which eliminates data redundancy. Principal Component Analysis (PCA) is one ...

Aug 27, 2019 · Two-dimensional input images of CNNs are more vulnerable to be redundant versus one-dimensional input time-series of conventional neural networks. In this study, we propose a new dimensionality reduction framework for reducing the dimension of CNN inputs based on the tensor decomposition of the time-frequency representation of EEG signals.
