But in many real-world applications, it is not necessary to find the global minimum for the networks to be useful. Q2. The advantage of softmax is that the sum over all outputs is equal to 1, which fits nicely to the requirement of posterior probability.

Tutorial: Neural Networks and Backpropagation. The weight update formula for the backpropagation algorithm for a DNN has the form: ... The following figure shows the decision boundary of a neural network with two inputs, one hidden layer (two hidden nodes), and one output. You may assume that the hidden and output nodes of the neural network ...

A MultiLayer Perceptron (MLP) [Bishop, 1995] is a neural network that is trained using backpropagation. MLPs consist of multiple layers of computational units that are connected in a feed-forward way forming a directed connection from lower units to a unit in a subsequent layer.

Neural Network and Deep Learning Optimization. Artificial Neural Networks (ANNs) have been a mainstay of Artificial Intelligence since the creation of the perceptron in the late 1950s. Since that time, it has seen times of promising development as well as years and decades of being ignored.

(2) In neural networks, where it is normally called “backpropagation”[1-3]. Surveys have shown. that backpropagation is used in a majority of the real-world applications of artificial neural networks (ANNs). This is the stream of work that I know best, and may even claim to have originated.
