Hidden Unit Specialization in Layered Neural Networks: ReLU vs. Sigmoidal Activation

no code implementations16 Oct 2019 Elisa Oostwal, Michiel Straat, Michael Biehl

We study layered neural networks of rectified linear units (ReLU) in a modelling framework for stochastic training processes.

Segmentation of blood vessels in retinal fundus images

no code implementations29 May 2019 Michiel Straat, Jorrit Oosterhof

In recent years, several automatic segmentation methods have been proposed for blood vessels in retinal fundus images, ranging from using cheap and fast trainable filters to complicated neural networks and even deep learning.

On-line learning dynamics of ReLU neural networks using statistical physics techniques

no code implementations18 Mar 2019 Michiel Straat, Michael Biehl

We introduce exact macroscopic on-line learning dynamics of two-layer neural networks with ReLU units in the form of a system of differential equations, using techniques borrowed from statistical physics.
