Towards Faster Matrix Diagonalization with Graph Isomorphism Networks and the AlphaZero Framework

CoRR
In this paper, we introduce innovative approaches for accelerating the Jacobi method for matrix diagonalization, specifically through the formulation of large matrix diagonalization as a Semi-Markov Decision Process and small matrix diagonalization as a Markov Decision Process.
