Prejudicial search and backprop

This paper introduces the combination of backward error propagation and prejudicial search. Prejudicial search is a method, which like simulated annealing, guarantees convergence to a global minimum as time approaches infinity. Unlike simulated annealing, its application is more flexible because it can be combined with other search methods. This method is applied to the exclusive-or problem. When prejudicial search is combined with backward error propagation, the resulting sum of mean squared error at each time step is between 10 and 70 percent (depending on t h e cooling schedule) of the normal backward error propagation error.
