        Artificial Neural Networks (ANNs) lie at the heart of the burgeoning field of Deep Learning.

        The purpose of an ANN is to link patterns of input data to associated output data.  For example, pharmaceutical companies generally wish to investigate possible links between the structure of potential drugs (molecular structure providing the input) and their effectiveness in treating disease (the output). Although it is reasonable to suppose that such correlations do exist, uncovering those relationships is a challenging task.

        ANNs comprise: (i) a set of computational nodes, each of which is able to perform simple mathematical operations; (ii) connections between those nodes; (iii) weights on the connections, and (iv) a computational recipe which defines how each node will calculate an output signal from the input signals it receives.

        The nodes are generally arranged in layers, the first of which accepts input from the outside. The input is passed through each layer of nodes in turn, with the final layer generating output signal(s). Learning is accomplished in the network through adjustment of the connection weights, which form the memory of the system. This process, known as "training", is generally the slowest step in using an ANN, often being hundreds or thousands of times slower than the actual application of the fully-trained network.
