Loss Surface Modality of Feed-Forward Neural Network Architectures

no code implementations24 May 2019 Anna Sergeevna Bosman, Andries Engelbrecht, Mardé Helbig

An increase in the hidden layer width is shown to effectively reduce the number of local minima, and simplify the shape of the global attractor.
