说明：  人工神经网络\神经网络的程序和训练数据 股票预测(Artificial Neural Networks \ neural network stock prediction programs and training data)

用混沌理论和广义回归神经网络进行短期负荷的预测，取得了满意的效果(with Chaos Theory and the general regression neural network for short-term load forecasts, achieved satisfactory results)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )
