Learning-Guided Integration Contours Construction for Fast Large-Scale Generalized Eigensolvers
Researchers have developed Deepcontour, a new framework that uses deep learning to optimize the construction of integration contours for solving large-scale Generalized Eigenvalue Problems (GEPs). This method employs a deep learning-based spectral predictor and Kernel Density Estimation to automatically design efficient contours, leading to significant speedups. The framework achieved up to a 5.63x performance increase on various scientific datasets while maintaining numerical accuracy. AI
