The most basic element of the human brain is a specific type of cell, which provides us with the ability to remember, think, and apply previous experiences to our every action [11]. An Artificial Neural Network (ANN) is an information processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information. Given a known set of true values Y k, we can compute a partial loss only with respect to this set for input sample X as L(Y k,Yˆ k). For a more detailed introduction to neural networks, Michael Nielsen’s Neural Networks and Deep Learning is a good place to start. 30. A deep neural network (DNN) can be considered as stacked neural networks, i.e., networks composed of several layers.. FF-DNN: FF-DNN, also known as multilayer perceptrons (MLP), are as the name suggests DNNs where there is more than one hidden layer and the network moves in only forward direction (no loopback). But a CNN has one or more than one convolutional layers that use a convolution operation on the input and then pass the result obtained in the form of output to the next layer. A recurrent neural network (RNN) is a class of artificial neural networks where connections between nodes form a directed graph along a temporal sequence. The motivation behind this paper is that the simple CNN architecture assumes a grid-like architecture and uses discrete convolution as its fundamental block. Gradient descent. Although, the structure of the ANN affected by a flow of information.
