Graph Cut and Its Application in Computer Vision 原文出处: http://lincccc.blogspot.tw/2011/04/graph-cut-and-its-application-in.html 现在好像需要代理才能访问了... 网络流算法最初用于解决流网络的优化问题,比如水管网络.通信传输和城市的车流等.Graph cut作为其中一类最常见的算法,用于求解流网络的最小割,即寻找一个总容量最小的边集合,去掉这个集合中的所有边将阻断这个网

Rethinking the Inception Architecture for Computer Vision 原文链接 摘要 卷积网络是目前最新的计算机视觉解决方案的核心,对于大多数任务而言,虽然增加的模型大小和计算成本都趋向于转化为直接的质量收益(只要提供足够的标注数据去训练),但计算效率和低参数计数仍是各种应用场景的限制因素.目前,我们正在探索增大网络的方法,目标是通过适当的分解卷积和积极的正则化来尽可能地有效利用增加的计算 引言 深度卷积架构上的架构改进可以用来改善大多数越来越多地依

\(\mathcal{Description}\)   Link.   给定 \(n\) 个点 \(m\) 条边的无向图,判断是否有给每条边定向的方案,使得 \(q\) 组有序点对 \((s,t)\) 都有 \(s\) 可达 \(t\).   \(n,m,q\le2\times10^5\). \(\mathcal{Solution}\)   首先,对于原图中的边双,显然是可以让它们互相可达的,考虑把边双缩点.   此后,图变成了一片森林.单独考虑一棵树,从 \(s\) 到 \(t\) 的有向路径

1.校验和:各数值相加,将溢出位加到最低位,之后将结果取反.若校验和全为0,则说明接收数据正确. 2.停等协议及计算信道利用率:利用率=(L/C)/(L/C+2*传输时延) 3.回退N帧协议(协议5),若保证发送流水线不断,则对序列号位数有要求,帧数=(往返时延+发送时间)/发送时间 4.计算三种协议信道利用率:(1)停等:k=1 (2)回退N:k=2^n-1 (3)选择重传:k=2^(n-1)

Windows 10正式版发布以后,新操作系统带来了许多的变化.现在新购买的电脑安装的系统应该是Windows 10.与当初用户不习惯Windows 7,购买新电脑后第一个想做的事情就是重装成XP,估计现在的Windows 10新用户也有这种冲动(安装Windows 7).界面方面的变化需要一些时间去消化和习惯,程序架构的变化则需要我们猿族去体验. 先看一张Windows 10的界面截图,点击开始菜单后,整个系统呈现的画面. 开始菜单回归到屏幕左下角,右键点击开始菜单弹出的菜单项包含系统管理的常
