摘要:

本文介绍了一种小波神经网络来学习滤波器组,以适应非平稳信号,提高数字信号处理的可解释性和性能。该网络使用小波变换作为神经网络的第一层,其中卷积是复Morlet小波的参数化函数。在简化数据和大气重力波上的实验结果表明,该网络收敛速度快,对噪声数据具有很好的泛化能力,并且优于标准网络结构。

英文摘要:

This work introduces a wavelet neural network to learn a filter-bank specialized to fit non-stationary signals and improve interpretability and performance for digital signal processing. The network uses a wavelet transform as the first layer of a neural network where the convolution is a parameterized function of the complex Morlet wavelet. Experimental results, on both simplified data and atmospheric gravity waves, show the network is quick to converge, generalizes well on noisy data, and outperforms standard network architectures.
