参数校验通常是OpenApi必做的操作,其会对不合法的输入做统一的校验以防止恶意的请求.本文则对参数校验这方面作下简单的分析 spring.factories 读者应该对此文件加以深刻的印象,很多springboot整合第三方插件的方式均是从此配置文件去读取的,本文关注下检验方面的东西.在相应的文件搜索validation关键字,最终定位至ValidationAutoConfiguration类,笔者这就针对此类作主要的分析 ValidationAutoConfiguration 优先看下其头上…

概要 class1 week3的任务是实现单隐层的神经网络代码,而本次任务是实现有L层的多层深度全连接神经网络.关键点跟class3的基本相同,算清各个参数的维度即可. 关键变量: m: 训练样本数量 n[l]:第l层的节点数量,输入认为是第0层 方括号上标[l]: 第l层 圆括号上标(i): 第i个样本 $$ X = \left[ \begin{matrix} \vdots & \vdots & \vdots & \vdots \\ x^{(1)} & x^{(2)} &…

C++ Core Guidelines September 9, 2015 Editors: Bjarne Stroustrup Herb Sutter This document is a very early draft. It is inkorrekt, incompleat, and pµøoorly formatted. Had it been an open source (code) project, this would have been release 0.6. Copy…

supervisor用来管理进程服务很方便 优点: 1.重启方便,无抖动感 2.可以分组管理进程 3.加入系统自动启动后,可以开机自启,程序异常退出能自动启动 操作: 1.在python沙箱环境下操作supervisor,进去python 沙箱虚拟环境(virtualenv) $source my_env/bin/activity 这个不会的自行谷歌下 2.安装supervisor $pip install supervisor 3.生成默认配置文件 安装好supervisor之后,默认是没有生…
