Generalizations Congratulations! You've learned five commands commonly used to navigate the filesystem from the command line. What can we generalize so far? The command line is a text interface for the computer's operating system. To access the comma…

做这题的时候发现题解里有提到\(generalizations\ of\ Cayley's\ formula\)的,当场懵逼,Wikipedia里也就带到了一下,没有解释怎么来的,然后下面贴了篇论文. 大概就是\(n\)个点\(k\)个联通块的森林,\(1,2,\cdots,k\)属于不同的联通块,这样不同的方案数共有\(k\cdot n^{n-k-1}\)种. 我自己用\(Prüfer\)序列脑补了半天没搞懂怎么来的,始终觉得感性理解是\(n^{n-k}\),然后就去看了下那个证明. 用\(F…

Texture tiling and swizzling 原帖地址:http://fgiesen.wordpress.com If you’re working with images in your program, you’re most likely using a regular 2D array layout to store image data. Which is to say, it’s basically a 1D array of width * height pixels,…

前言: 这次实验完成的是图模型的精确推理.exact inference分为2种,求边缘概率和求MAP,分别对应sum-product和max-sum算法.这次实验涉及到的知识点很多,不仅需要熟悉图模型的representation,而且还需明白图模型的inference理论,大家可参考coursera课程:Probabilistic Graphical Models的课件和视频.多花点功夫去理解每行代码,无形之中会收获不少.新年第一篇博客,继续加油! 算法流程: Sum-product求条件概…

第四部分     推理题 1.世界上每个角落的每个人都有立场,都有背景,都有推理性,能推理出一个人语言的真意,才成就了真正的推理能力: 2.换言之,如果你能通过一个人的说话推理出其身份职业,你的推理能力更上一层楼. 一 . 临门一脚 1. “I believe in human ingenuity – that when we decide on a task to be done, no matter how daunting it may seem at the beginning, we…
