On the Lipschitz Constant of Deep Networks and Double Descent

1 code implementation28 Jan 2023 Matteo Gamba, Hossein Azizpour, Mårten Björkman

Existing bounds on the generalization error of deep networks assume some form of smooth or bounded dependence on the input variable, falling short of investigating the mechanisms controlling such factors in practice.

Deep Double Descent via Smooth Interpolation

1 code implementation21 Sep 2022 Matteo Gamba, Erik Englesson, Mårten Björkman, Hossein Azizpour

The ability of overparameterized deep networks to interpolate noisy data, while at the same time showing good generalization performance, has been recently characterized in terms of the double descent curve for the test error.

Hyperplane Arrangements of Trained ConvNets Are Biased

1 code implementation17 Mar 2020 Matteo Gamba, Stefan Carlsson, Hossein Azizpour, Mårten Björkman

We investigate the geometric properties of the functions learned by trained ConvNets in the preactivation space of their convolutional layers, by performing an empirical study of hyperplane arrangements induced by a convolutional layer.
