TL;DR

The applicability of PDP (parallel distributed processing) models to knowledge processing is clarified and a method to extract rules from the network and usage of the rules in a confirmation process are proposed.

Abstract

The applicability of PDP (parallel distributed processing) models to knowledge processing is clarified. The authors evaluate the diagnostic capabilities of a prototype medical diagnostic expert system based on a multilayer network. After having been trained on only 300 patients, the prototype system shows diagnostic capabilities almost equivalent to those of a symbolic expert system. Symbolic knowledge is extracted from what the multilayer network has learned. The extracted knowledge is compared with doctors' knowledge. Moreover, a method to extract rules from the network and usage of the rules in a confirmation process are proposed.>

Back-propagation repeatedly adjusts the weights of the connections in the network so as to minimize a measure of the difference between the actual output vector of the net and the desired output vector, which helps to represent important features of the task domain.

The authors present a time-delay neural network (TDNN) approach to phoneme recognition which is characterized by two important properties: using a three-layer arrangement of simple computing units, a hierarchy can be constructed that allows for the formation of arbitrary nonlinear decision surfaces, which the TDNN learns automatically using error backpropagation.

135 Citations1987Waltz

The Connection Machine is programmed in conservative extensions of Common Lisp and C, so as to provide familiar programming environments and users familiar with these languages and with front-end computer systems have been able to produce results on the Connection Machine on the first day that they use it.
