We study the wellposedness, the large time solution behavior, and the characterization of the steady states for the forward problem. Several useful time-uniform estimates and stability/instability conditions are presented. We state and prove optimality conditions for the inverse deep learning problem, using the Hamilton-Jacobi-Bellmann equation and the Pontryagin maximum principle. This serves to establish a mathematical foundation for investigating the algorithmic and theoretical connections between optimal control and deep learning.", "revisions": [ { "version": "v1", "updated": "2019-05-22T11:16:58.000Z" } ], "analyses": { "subjects": [ "49K20", "49L20" ], "keywords": [ "deep neural networks", "selection dynamics", "large time solution behavior", "deep residual neural networks", "pde optimal control problem" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
