Kernel-Based Regression in Transient Nonlinear Electro-Quasistatic Field Simulations

During high resolution transient electro-quasistatic field simulations, large sparse nonlinear algebraic systems need to be solved iteratively at each timestep. In previous works, the subspace projection extrapolation method and the Gaussian process regression method succeeded in providing improved start values with known previous transient solutions. In this work, a kernel-based regression model ...
