(1)先运行kaggle创建notebook自带的code cell来查看数据的位置。图三是运行结果。 # This Python 3 environment comes with many helpful analytics libraries installed # It is defined by the kaggle/python Docker image: https://github.com/kaggle/docker-python # For example, here's several helpful packag...
这个线性回归的作业需要上传到https://inclass.kaggle.com/c/ml2016-pm2-5-prediction 上面,这是一个kaggle比赛的网站。第一次接触听说这个东西,恰好在京东上有一本刚出来的关于这个的书《Python机器学习及实践:从零开始通往Kaggle竞赛之路》。把我自己写的代码运行保存的结果提交上去后发现,损失函数值很大,baseline是...

The generalized linear model has the same implementation as the general linear regression, pointed above, because the general linear model is just a special case. The generalized linear model allows applying a function on the output and that's about it....

学习Linear Regression in Python – Real Python,前面几篇文章分别讲了“regression怎么理解“,”线性回归怎么理解“,现在该是实现的时候了。 线性回归的 Python 实现:基本思路 导入Python 包: 有哪些包推荐呢? Numpy:数据源 scikit-learn:ML statsmodels: 比scikit-learn功能更强大 ...
