This is a C ++ based code

if you are Chinese:

这个代码是用一个单纯的BP网络写出来的软测量代码

代码很简单，在代码里面也有注释。

数据分为两个部分： 第一 训练数据 train_in 是输入数据，train_out是输出数据。在训练的时候 第二 测试数据 测试的时候用test_in 然后将预测的数据与test_out数据对比。

该数据是某化工厂生产聚氯乙烯是，氯乙烯单体的转化率与转化速率的数据，数据意义非常大，大家使用的时候请给star 星星

if you can not understand Chinese please:

This code is a soft measurement code written using a pure BP network

The code is very simple, and there are comments in the code.

The data is divided into two parts: The first training data train_in is input data and train_out is output data. During training Second test data Use test_in when testing and then compare the predicted data with test_out data.

This data refers to the conversion rate and conversion rate of vinyl chloride monomer produced by a chemical plant. The data is of great significance. Please give me a star when you use it.
