Model Reduction With MapReduce-enabled Tall and Skinny Singular Value Decomposition
Model Reduction With MapReduce-enabled Tall and Skinny Singular Value Decomposition
We present a method for computing reduced-order models of parameterized partial differential equation solutions. The key analytical tool is the singular value expansion of the parameterized solution, which we approximate with a singular value decomposition of a parameter snapshot matrix. To evaluate the reduced-order model at a new parameter, we …
