Linear Regression线性回归虽然看上去简单,但是其是最重要的数学模型之一,其他很多模型都建立在它的基础之上。 Linear Regression的表达式子如下: 1 2 3 4 y = Ax + B. A = slope of curve B = bias (point that intersect y-axis) 在本次例子中使用一组汽车价格和销量数据来进行模拟研究。

实际上上述中分为训练数据和测试数据,都是CSV格式的,而且只用到PM2.5有用,其他的没什么用,同时通过测试数据才知道, 其实就是用前9个小时的PM2.5数据作为特征,来预测第10个小时的数据,将第10个小时的数据保存为csv格式,作为预测结果。 好了,不多说,上代码。我的开发环境还是win7+pycharm4.0 第一步,读取train....
