Perceptual Learning Model on Recognizing Chinese Characters
Perceptual learning is the improvement in performance on a variety of simple sensory tasks through practice. Based on the perceptual model, with the lateral interaction applied to the neurons of the middle layer, a neural network is developed to simulate the transition of perceptual mode from global perception to local perception in the process of Chinese characters learning. Using some Chinese characters with the same structure to train the network, the components and radicals of the Chinese characters can be extracted through the local perceptual mode. The perceptual learning process under the damage of neural connections is also simulated, and the result are coincident with the somatosensory cortex changes experiment on owl monkeys. It is a self-organization process, in which the lateral interaction among the neurons are the core mechanism.
