Finite-time Lyapunov exponents of deep neural networks

no code implementations21 Jun 2023 L. Storm, H. Linander, J. Bec, K. Gustavsson, B. Mehlig

We compute how small input perturbations affect the output of deep neural networks, exploring an analogy between deep networks and dynamical systems, where the growth or decay of local perturbations is characterised by finite-time Lyapunov exponents.

Looking at the posterior: accuracy and uncertainty of neural-network predictions

no code implementations26 Nov 2022 H. Linander, O. Balabanov, H. Yang, B. Mehlig

Here we show that prediction accuracy depends on both epistemic and aleatoric uncertainty in an intricate fashion that cannot be understood in terms of marginalized uncertainty distributions alone.
