Wavelet neural network(WNN) has become a research hotspot as a novel approximal tool.It absorbs the merits of neural network and wavelet transform and trains network to adjust the shape of wavelets.

• 小波神经网络作为一种新的逼近工具已成为目前研究的热点,它继承了神经网络和小波变换的优点,通过训练自适应的调整小波基的形状实现小波变换,比单纯的小波分解使用更少的基函数单元,比BP网络具有更快的收敛速度。
