On the other hand, they provide solutions to a broad range of specific problems in applied engineering, such as speech recognition, financial forecasting, or object classification. 36.2.1 But What is a Neural Network? Despite its “biological” sounding name, neural networks are actually quite ...
Deep Neural Network for Image Classification: Application When you finish this, you will have finished the last programming assignment of Week 4, and also the last programming assignment of this course! You will use use the functions you'd implemented in the previous assignment to build a deep ...
In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.

The advantage of BPNN is that its backpropagation of error which has also been increased to other neural network to improve the performance, and it also has strong nonlinear mapping ability. Thus, it can effectively accomplish identification and classification tasks for nonlinear data by approximating...
(the number of nodes) of the hidden layer. The more nodes we put into the hidden layer the more complex functions we will be able fit. But higher dimensionality comes at a cost. First, more computation is required to make predictions and learn the network parameters. A bigger number of ...
