A Kind of SA-ART Neural Network Mode Used in the Identification of Handwriting Characters |
| |
Abstract: | The ART-network and the BP-network are usually used in identifying handwriting characters. Although the ART-network in identifying handwriting characters is more powerful than the BP-network, the improvement is limited and the accuracy of the identification is much lower than that excepted. On the basis of a lot of practical and theoretical experiments, we brought forward one kind of ART modes called SA-ART (Selective Attention-Adaptive Resonance Theory) aiming at the BP-network's and the ART-network's deficiencies and the human cognition mechanism. The SA-ART has the selective ability. After making plenty of practical tests, it was found that the accuracy of the AR-SART is much higher than before. |
