Researchers have developed a novel neural network approach to significantly speed up the computation of pseudospectra for structured non-normal banded matrices. This method avoids exhaustive evaluation across the complex plane by predicting and focusing computation on spectrally sensitive regions. Numerical experiments show substantial speedups compared to traditional methods while maintaining high accuracy. AI
