Instabilities in Convnets for Raw Audio

1 code implementation11 Sep 2023 Daniel Haider, Vincent Lostanlen, Martin Ehler, Peter Balazs

Numerical simulations align with our theory and suggest that the condition number of a convolutional layer follows a logarithmic scaling law between the number and length of the filters, which is reminiscent of discrete wavelet bases.

Convex Geometry of ReLU-layers, Injectivity on the Ball and Local Reconstruction

1 code implementation18 Jul 2023 Daniel Haider, Martin Ehler, Peter Balazs

The paper uses a frame-theoretic setting to study the injectivity of a ReLU-layer on the closed ball of $\mathbb{R}^n$ and its non-negative part.

An amplified-target loss approach for photoreceptor layer segmentation in pathological OCT scans

no code implementations2 Aug 2019 José Ignacio Orlando, Anna Breger, Hrvoje Bogunović, Sophie Riedl, Bianca S. Gerendas, Martin Ehler, Ursula Schmidt-Erfurth

Supervised deep learning models trained with standard loss functions are usually able to characterize only the most common disease appeareance from a training set, resulting in suboptimal performance and poor generalization when dealing with unseen lesions.

The Algebraic Approach to Phase Retrieval and Explicit Inversion at the Identifiability Threshold

no code implementations17 Feb 2014 Franz J. Király, Martin Ehler

We study phase retrieval from magnitude measurements of an unknown signal as an algebraic estimation problem.
