Basics of Artificial neural network


A neural network is a network of neurons or, in a contemporary context, an artificial neural network made up of artificial neurons or nodes. An artificial neural network is influenced by a biological neural network. As a biological neural network is made up of true biological neurons, in the same manner, an artificial neural network is made from artificial neurons called “Perceptrons“. An artificial neural network is developed for solving artificial intelligence (AI) problems. Artificial neuron links are termed as weights. All inputs are weight-modified and summed up. This activity is called a linear combination. Finally, the output is controlled by an activation function applied over that linear combination "
