Multivariate sensitivity-adaptive polynomial chaos expansion for high-dimensional surrogate modeling and uncertainty quantification
Dimitrios Loukrezis, Eric Diehl, Herbert De Gersem
This work develops a novel basis-adaptive method for constructing anisotropic polynomial chaos expansions of multidimensional (vector-valued, multi-output) model responses. The ada…
Error Approximation and Bias Correction in Dynamic Problems using a Recurrent Neural Network/Finite Element Hybrid Model
Moritz von Tresckow, Herbert De Gersem, Dimitrios Loukrezis
This work proposes a hybrid modeling framework based on recurrent neural networks (RNNs) and the finite element (FE) method to approximate model discrepancies in time dependent, mu…
Data-driven Modified Nodal Analysis Circuit Solver
Armin Galetzka, Dimitrios Loukrezis, Herbert De Gersem
This work introduces a novel data-driven modified nodal analysis (MNA) circuit solver. The solver is capable of handling circuit problems featuring elements for which solely measur…
