从TP.FP.TN.FN到ROC曲线.miss rate.行人检测评估 想要在行人检测的evaluation阶段要计算miss rate,就要从True Positive Rate讲起:miss rate = 1 - true positive rate true positive rate毕竟是一个rate,是一个比值.是谁和谁比呢?P 要从TP.FP.TN.FN讲起. 考虑一个二分类问题:一个item,它实际值有0.1两种取值,即负例.正例:而二分类算法预测出来的结果,也只有0.1两种取值,

一.前言 上一篇文章中粗浅的介绍使用Redis和基于令牌桶算法进行对服务接口API限流,本文介绍另一种算法---漏桶算法的应用.Nginx想必大家都有所了解是一个高性能的 HTTP 和反向代理服务器,优秀而强大的Nginx依然可以处理限制来自单个IP地址的请求处理频率.ngx_http_limit_conn_module模块可以限制请求数即通过定义的键值来限制请求处理的频率.该模块其采用漏桶算法,每秒固定处理请求数,推迟延迟请求. 二.ngx_http_limit_conn_module模块指令

一.场景描述 很多做服务接口的人或多或少的遇到这样的场景,由于业务应用系统的负载能力有限,为了防止非预期的请求对系统压力过大而拖垮业务应用系统. 也就是面对大流量时,如何进行流量控制? 服务接口的流量控制策略:分流.降级.限流等.本文讨论下限流策略,虽然降低了服务接口的访问频率和并发量,却换取服务接口和业务应用系统的高可用. 实际场景中常用的限流策略: Nginx前端限流 按照一定的规则如帐号.IP.系统调用逻辑等在Nginx层面做限流 业务应用系统限流 1.客户端限流 2.服务端限流 数据库限

在Gnuradio中,我们可以看到很多模块中都有Sample rate 这个概念 然后看到一个说明 Any processing block's 'Sample Rate' parameter is used for DSP calculation, not for controlling the rate at which samples are produced. This is distinct from a hardware(or Throttle) block where it is 

概要: 微软研究院的人写的文章,提出用逻辑回归来解决ctr预估问题,是以后ctr的经典解决方式,经典文章. 详细内容: 名词: CPC -- cost per click CTR -- click through rate 1. 研究初衷 搜索引擎主要靠商业广告收入,在广告位上面打广告,用户点击,之后广告商付费.在通用搜索引擎,通常广告位置是在搜索结果之前,或者在搜索结果右边. 商业广告收入 = pClick * CPC 要提升广告收入,关键问题是在有限的广告为上面,放什么广告?非常自然的想法就
