说明：   利用线性神经网络进行自适应预测 利用函数adapt对线性网络进行自适应训练，在线修正网络的权值和阈值，这样对于时变信号，网络就可以及时跟踪其变化，即可对时变信号序列进行预测。
(linear adaptive neural network prediction using linear function adapt to the network adaptive training , the online network that the weights and thresholds, so for the time-varying signal, the network can track changes in a timely manner. will be the time-varying signal sequence forecast.)
