A regular 3-layer neural network consists of input – hidden layer 1 – hidden layer 2 – output layer. CNN arrange the neurons into three dimensions of width, height, and depth. Each layer will transform the 3D input to 3D output volume of neuron activations. Hence, the red input layer ...

local minima vs saddle points in deep learning

WitrynaSeveral gradient-based methods have been developed for Articial Neural Network (ANN) training. Still, in some situations, suchprocedures may lead to local minima, making Evolutionary Algorithms(EAs) a promising alternative. In this work, EAs using direct representationsare applied to several classication and regression ANN … WitrynaWe prove that for a neural network with one hidden layer using rectiﬁed linear units under realistic assumptions. There are poor regions that lead to poor local minima, and we explain why such regions exist even in the overparameterized DNNs. 1 INTRODUCTION Deep Neural Networks (DNNs) have achieved state-of-the-art …
