Dimensionality reduction can be used as a surrogate model for high-dimensional forward uncertainty quantification
Jungho Kim, Sang-ri Yi, Ziqi Wang
We introduce a method to construct a stochastic surrogate model from the results of dimensionality reduction in forward uncertainty quantification. The hypothesis is that the high-…
