File:Recurrent ann dependency graph.png

Summary
A dependency graph for a recurrent artificial neural network. The top of the figure depicts the commonly used visualisation of such a recurrent network, with f being dependent upon itself. However this is slightly misleading, as f is only dependent upon the value that it had at some previous time. The graphical model shown at the bottom of the figure makes the dependencies between the variables clear.
