The artificial neural network (ANN) model is a machine learning model that is inspired by how a human brain functions. Recent successful applications of ANN models in image recognition, voice recognition, and robotics have proven their predictive power and usefulness in various industries. You might have heard the term deep learning. This is a type of ANN model where the number of layers between the input and output layers is large. It is best explained with the following diagram:
This diagram shows a simple case of an ANN model with one hidden layer. The circles in this diagram represent artificial neurons or nodes, which model those neurons in human brains. The arrows represent how signals are transmitted from one neuron to another. As this diagram suggests, an ANN model learns by finding the patterns or the weights of signals from each input neuron...
