An adaptation method for a data processing system comprising a plurality of neurons each of which outputs an output according to a comparison between a sum of multiplied inputs by weights and a threshold, characterized in the threshold of the neuron which has generated significant output at certain point of time is compulsorily increased to a maximal value and the weight of the neuron is adapted for a constant value of the inputs wherein the threshold is decreased to a value at the point.

A method for maximizing an efficiency of a data processing system receiving training data, said method comprising the steps of: inputting said training data to said system, said system comprising a neural network having a plurality of neurons each of which is capable of outputting a signal when a weighted sum of inputs has a predetermined relationship to a threshold; determining a first neuron which outputs a signal in response to said training data, and compulsorily increasing a threshold of said first neuron up to a maximum value; determining a second neuron which did not output a signal in response to said training data, and adapting weights of said second neuron so that weights to be multiplied to inputs of the second neuron are increased when said threshold of said first neuron is increased; and decreasing said threshold of said first neuron after adapting said weights of said second neuron, thereby adapting said neural network to provide an even ignition pattern without generating a local minimum.
