Abstract(in English) | Using supervised learning, an input-output relation corresponding to feature extraction in 2 dimensional figures could be obtained in a 3 layered neural network. To analyze the mechanism for feature extraction in this network, we studied the reverse projection map of connection weights(RPMCW) from an output neuron upon the input layer. Each PRMCW showed excitatory area coinciding with the shape of feature assigned to the neuron. Strong inhibitory area was found at the position where a segment of different feature lies. Because the feature assigned to the output neuron shares segments with the other features, inhibitory area cffectively rejects the features which have overlapping segment similarly in the lateral inhibition in the brain. |
