An Artificial Neural Network (ANN) is a form of Machine Learning. A common feature of ANNs is the use of layers of artificial neurons (called nodes). Each node within a layer is an individual software module that, as part of its collaboration on a shared ANN task, processes an input. If the result from a single node meets (or exceeds) a threshold value, the data point is passed to the next layer within the ANN. This result may, in some cases, be modified by the results produced by other nodes.
