Geometric Foundations of AI with Applications to Finance, Control, and PDEs

Applications to: Finance, Control, and PDEs

We investigate the analytic and statistical foundations of deep learning. By understanding the behaviour of these models, we rigorously modify them to efficiently encode structures arising in finance, stochastic processes, games, and PDEs.
