Based on the error for each pixel, it works backward through the network to improve the feature extraction. There are two Artificial Neural Network topologies − FeedForward and Feedback. Artificial neural networks (ANNs) are a powerful class of models used for nonlinear regression and classification tasks that are motivated by biological neural computation. Backpropagation is the tool that played quite an important role in the field of artificial neural networks. These network of models are called feedforward because the information only travels forward in the neural network, through the input nodes then through the hidden layers (single or many layers) and finally through the output nodes. After this Neural Network tutorial, soon I will be coming up with separate blogs on different types of Neural Networks – Convolutional Neural Network and Recurrent Neural Network. Neuron in ANNs tends to have fewer connections than biological neurons. It provides an algorithm to update weight of neuronal connection within neural network. What Is A Recurrent Neural Network?
