这个是基于最初始的极限学习机的例子，分别用于回归和分类(This is an example based on the initial limit learning machine, which is used for regression and classification, respectively)

针对数据分类问题，提出了基于极限学习机的分类方法，将数据样本分为训练样本和测试样本，并采用准确率指标进行评价。(Aiming at the problem of data classification, a classification method based on extreme learning machine is proposed. The data samples are divided into training samples and test samples, and the
