演講摘要:

Large-scale eigenvalue problems arise in a wide variety of scientific and engineering applications such as nano-scale materials simulation, vibration analysis of automobile components, data clustering, etc.

Principal components analysis (PCA) and spectral clustering are well-known examples of the application of eigenvalue problems. In this talk, we introduce the Sakurai-Sugiura method (SSM) for large-scale eigenvalue problems. Based on this method, we are developing a high-performance analysis engine for simulation and data analysis. Recently, we are also developing a high-performance algorithm for deep neural networks. Some numerical examples illustrate properties of our methods.
