It was concluded by comparing three different preprocessing methods that the power spectra of alpha rhythm in wavelet transform domain could be used to predict epileptic seizures. The extraction of its envelope and nonlinear transform to the envelope provided further improvement of the performance of RNN effectively.

通过比较三种不同的预处理方法，发现在小波变换域利用脑电信号α节律的能量谱可以实现发作预报，而进一步提取包络并作非线性变换可以有效地提高RNN的预报性能。

for example, during rest, brain activity slows down to an alpha rhythm of about eight to 10 hertz, or cycles per second.

例如，在休息时候，大脑活动频率降到阿尔法节律---它是脑波中一种8到10赫兹（或者每秒钟周数）的波动。
