متن کاملSparsity via Linear - Time Projection
We present an efficient spectral projected-gradient algorithm for optimization subject to a group `1-norm constraint. Our approach is based on a novel linear-time algorithm for Euclidean projection onto the `1and group `1-norm constraints. Numerical experiments on large data sets suggest that the proposed method is substantially more efficient and scalable than existing methods.
متن کاملAIAA 2001–0926 Investigation of Non-Linear Projection for POD Based Reduced Order Models for Aerodynamics
In this paper a method for inviscid airfoil analysis and design optimization using reduced order models has been reviewed, modifications to the methodology are proposed, and new results of flow computations and design optimization are presented. The goal of these reduced order models is to obtain solutions to the Euler equations with sufficient accuracy for design optimization, at a computation...
متن کاملOn Model Order Reduction via Projection
The paper investigates the properties of reduced order models obtained by projection of a high order system. It answers questions such as are any two models of different orders related by a projection? Is it possible to obtain the same reduced order model using different projections? Etc. It is shown that in cases where not all models of a certain reduced order can be obtained by a projection, ...
متن کاملSupport-Vector-Machine-Based Reduced-Order Model for Limit Cycle Oscillation Prediction of Nonlinear Aeroelastic System
It is not easy for the system identification-based reduced-order model ROM and even eigenmode based reduced-order model to predict the limit cycle oscillation generated by the nonlinear unsteady aerodynamics. Most of these traditional ROMs are sensitive to the flow parameter variation. In order to deal with this problem, a support vector machineSVMbased ROM was investigated and the general cons...
