Influence of the noise on english letters recognition by neural network model 英文字母中的噪声信号对神经网络模型识别的影响
2.
The experiment on handwritten english letter recognition in ? . 1 shows that the error rate of t - ppca is significantly smaller than that of gaussian - ppca ( see table 5 . 1 ) 1的手写英文字母识别的实验中，结果表明t - ppca的错误率大大小于使用gaussian - ppca的错误率(见表5 1 ) 。
