摘要 通过实验研究ELM算法中随机映射的作用及神经网络中隐含层结点个数对网络泛化能力的影响。在35个数据集上进行实验,针对不同的数据集,找到网络的最优精度所对应的隐含层结点个数。实验结果表明,当随机映射使数据升维到一定维数时,网络性能得到提高。 This paper studies the problem with experimental approach.It also investigates the impact of number of hidden layer nodes to generalization performance of Single Hidden Layer Feedforward Neural Network(SLFNN).Experiment on Extreme Learning Machine(ELM) with 35 databsets is made.For different databases,the optimal number of hidden layer nodes with respect to best test accuracy is found,and the performance of SLFNN can be improved by randomly mapping the data into a fixed high dimensional space with ELM algorithm.
