132 results about "Madaline" patented technology

MADALINE is a three-layer, fully connected, feed-forward artificial neural network architecture for classification that uses ADALINE units in its hidden and output layers, i.e. its activation function is the sign function. The three-layer network uses memistors. Three different training algorithms for MADALINE networks, which cannot be learned using backpropagation because the sign function is not differentiable, have been suggested, called Rule I, Rule II and Rule III. The first of these dates back to 1962 and cannot adapt the weights of the hidden-output connection. The second training algorithm improved on Rule I and was described in 1988. The third "Rule" applied to a modified network with sigmoid activations instead of signum; it was later found to be equivalent to backpropagation. The Rule II training algorithm is based on a principle called "minimal disturbance". It proceeds by looping over training examples, then for each example, it: finds the hidden layer unit with the lowest confidence in its prediction, tentatively flips the sign of the unit, accepts or rejects the change based on whether the network's error is reduced,
