Universal Approximation Constraints of Narrow ResNets: The Tunnel Effect
Christian Kuehn, Sara-Viola Kuntz, Tobias Wöhrer
We analyze the universal approximation constraints of narrow Residual Neural Networks (ResNets) both theoretically and numerically. For deep neural networks without input space aug…

Tracking Finite-Time Lyapunov Exponents to Robustify Neural ODEs
Tobias Wöhrer, Christian Kuehn
We investigate finite-time Lyapunov exponents (FTLEs), a measure for exponential separation of input perturbations, of deep neural networks within the framework of continuous-depth…
