代码说明:

应用背景信号处理,DFT离散信号处理,可用于对采样数据的处理,离散变化关键技术这是我在研究生数学建模比赛用到的一小段程序,在比赛中用改程序提取傅里叶系统,这样可以作为一个特征向量来区别场景。

Two key reasons behind may be: (1) the slow gradient-based learning algorithms are extensively used to train neural networks, and (2) all the parameters of the networks are tuned iteratively by using such learning algorithms. Unlike these conventional implementations, this paper proposes a new learning algorithm called extreme learning machine (ELM) for single-hidden layer feedforward neural networks (SLFNs) which randomly chooses hidden nodes and analytically determines the output weights of SLFNs. In theory, this algorithm tends to provide good generalization performance at extremely fast learning speed. The experimental results based on a few artificial and real benchmark function approximation and classification problems including very large complex applications show that the new algorithm can p)
