Where n represents the total number of features and X represents the value of the feature. 2 History. A neural network is a massively parallel, distributed processor made up of simple processing units (artificial neurons). It resembles the brain in two respects: –  Knowledge is acquired by the network from its environment through a learning process –  Synaptic connection strengths among neurons … 2. INTRODUCTION • As we have noted, a glimpse into the natural world reveals that even a small child is able to do numerous tasks at once. Developed by Frank Rosenblatt by using McCulloch and Pitts model, perceptron is the basic operational unit of artificial neural networks. Perceptron was introduced by Frank Rosenblatt in 1957.
