15.5 Content-Encoding:内容编码 HTTP 应用程序有时在发送之前需要对内容进行编码。常见的比如服务器利用 gzip 进行压缩,减少传输实体的时间。 1. 内容编码过程 内容编码的过程: 网站服务器生成原始响应报文,其中有原始的 Content-Type 和 Content- Length 首部。 内容编码服务器(也可能就是原始的服务器或下行的代理...

对数据框中的因子型和字符串变量快速高效地创建哑变量。在网上搜哑变量和one-hot encoding,碰巧看到的。感觉还是python比较适合,依赖一个库就好,R真是各个包,不继续维护的话,没准有很多坑。 Function categories 主要作用:抽取分类变量的值,是生成哑变量的预处理工作。

The Dummy Variable Trap occurs when two or more dummy variables created by one-hot encoding are highly correlated (multi-collinear). This means that one variable can be predicted from the others, making it difficult to interpret predicted coefficient variables in regression models. In other words,...
