A prototypical connectionist expert system is presented. DESKNET is built for ultimate use in the instruction of medical students to diagnose papulosquamous skin diseases. DESKNET is an ES composed of a three layered back propagation network consisting of an input layer, a hidden layer, and an output layer. The units on a layer have excitatory or inhibitory connections to units on the adjacent layers. Input for the system is a list of symptoms organized by 18 parameters. The back propagation algorithm encodes the implicit 'knowledge' such that it remains in an implicit form; thus, more knowledge can be captured. Therefore, the back propagation model appears to be a useful tool for representing concepts of a domain and encoding them in a network. Limitations of the algorithm are identified.
