Numerical simulation reveals the usefulness of the dimension-reduction representation methods.
Following the development of Error Reduction and Representation In Stages (ERRIS) for daily streamflow forecasting, we extend ERRIS to streamflow forecasting at an hourly time step (ERRIS-h).
Aiming at making up for this deficiency, we designed a novel classification framework that performs unsupervised optimal feature selection (UOFS) to simultaneously integrate dimensionality reduction, sparse representation, jointly sparse feature extraction and feature selection as well as classification into a unified optimization objective.
By introducing random functions as constraints correlating the orthogonal random variables involved in the unified formulation, the dimension-reduction spectral representation method (DR-SRM) and the dimension-reduction proper orthogonal decomposition (DR-POD) are addressed.
Field (1972) anticipated a naturalist reduction of the representation via a causal theory, but any view that accepts representation relations for truth bearers or their constituents can provide a similar theory of truth.
The representation, reduction type, synergy metric and activity metric may be set by drop down menus in the top bar.
Besides, Principal Component Analysis with a Whitening process is applied for the final feature vector dimension reduction, making the representation more compact and discriminative.
During the APT tests, a portable seismic property analyzer (PSPA) was used to monitor the modulus reduction as a representation of the pavement deterioration.
Efficiency also has weaknesses: it implies no loss or reduction of feature representation before (or after) conservation is implemented.
Previous work by the author addressed the reduction of modal representations by eliminating entire modes or individual modal elements (inertial, compliant, resistive).
This research proposes a generic methodology for dimensionality reduction upon time frequency representations applied to the classification of different types of biosignals.
