Convergence properties of backpropagation algorithm

Summary form only given, as follows. The author presents results regarding the convergence properties of the backpropagation algorithm for XOR circuits. Specifically, the behavior has been investigated in the presence of noise. As a performance metric, the author has determined the solution density as several parameters are varied. Some issues relating to asynchronous implementation as well as behavior in the presence of ambiguity are also briefly explored.<>
