We propose Twin SVM, a binary SVM classifier that determines two nonparallel planes by solving two related SVM-type problems, each of which is smaller than in a conventional SVM. The Twin SVM formulation is in the spirit of proximal SVMs via generalized eigenvalues. On several benchmark data sets, Twin SVM is not only fast, but shows good generalization.… (More)
A pair of linear primal-dual problems is introduced under fuzzy environment and appropriate results are proved to establish the duality relationship between them. Possible extensions are also suggested.
PURPOSE To determine specific retinal precursor lesions and sequence of events preceding the onset of geographic atrophy (GA) in eyes with age-related macular degeneration (AMD). DESIGN Retrospective review. PARTICIPANTS All participants in the Age-Related Eye Disease Study (AREDS) at 2 clinical centers (Devers Eye Institute, Portland, Oregon, and… (More)
A dual for linear programming problems with fuzzy parameters is introduced and it is shown that a two person zero sum matrix game with fuzzy pay-oos is equivalent to a primal–dual pair of such fuzzy linear programming problems. Further certain diiculties with similar studies reported in the literature are discussed.
In this paper, we use the approach of adaptive critic design (ACD) for control, specifically, the action-dependent heuristic dynamic programming (ADHDP) method. A least squares support vector machine (SVM) regressor has been used for generating the control actions, while an SVM-based tree-type neural network (NN) is used as the critic. After a failure… (More)
