Researchers have developed a new method called the Sorting Chebyshev Subspace Filter (SCSF) to accelerate the generation of eigenvalue datasets for training neural eigenvalue methods. This approach leverages similarities between operators, a factor previously overlooked, to reduce redundant computations. SCSF utilizes fast Fourier transform sorting and a Chebyshev subspace filter to reuse eigenpairs from solved problems, achieving up to a 3.5 times speedup compared to traditional numerical solvers.
