http://acm.hdu.edu.cn/showproblem.php?pid=5873 题意: 现在有比赛,所有队伍两两进行比赛,赢的积2分,输的积0分,如果平局的话就各自都积1分,现在给出每只队伍的得分情况,判断是否合法. 思路: 竞赛图中有关于得分序列这方面的知识,这里引用一下来自http://blog.csdn.net/a_crazy_czy/article/details/73611366博主的讲解. 那么,对于这道题目来说,首先对所有得分排个序,再依次处理即可,前i只队伍的得分情…
随便判了几个条件就过了,也不知道对不对的. 正解应该是: $[1].$${s_1} + {s_2} + {s_3} + ...... + {s_n} = n(n - 1)$ $[2].$${s_1} + {s_2} + {s_3} + ...... + {s_i} ≥ i(i - 1)$ #pragma comment(linker, "/STACK:1024000000,1024000000") #include<cstdio> #include<cstring&g…

1006 Football Games 这道题输入也很阴险!!! 这道题过题姿势最优雅的,不是if else if else if.那样很容易wa的. 如果没有平手选项, 赢得加一分的话, 可以用Landau's Theorem(兰道定理)判定. 稍微修改一下这个定理就能做了. 假设S1,S2……Sn是他们的得分序列,从小到排个序.那么这个序列要是合法.那么当且仅当 S1+S2+……+Sn = n(n-1) S1+S2+……+Si >= i(i-1)  ( 1 <= i < n) 其实第…
计算机视觉中的词袋模型(Bow,Bag-of-words) Bag-of-words 读 'xw20084898的专栏'的blogBag-of-words model in computer vision Bag-of-words 模型 之前教研室有个小伙伴在做文本方面的东西,经常提及词袋模型,只知道是文本表示的一种,可是最近看的关于CV的论文中也出现BoW模型,就很好奇BoW到底是个什么东西. BoW起始可以理解为一种直方图统计,开始是用于自然语言处理和信息检索中的一种简单的文档表示方法. 和…

BOW (bag of words) 模型简介 Bag of words模型最初被用在文本分类中,将文档表示成特征矢量.它的基本思想是假定对于一个文本,忽略其词序和语法.句法,仅仅将其看做是一些词汇的集合,而文本中的每个词汇都是独立的.简单说就是讲每篇文档都看成一个袋子(因为里面装的都是词汇,所以称为词袋,Bag of words即因此而来),然后看这个袋子里装的都是些什么词汇,将其分类.如果文档中猪.马.牛.羊.山谷.土地.拖拉机这样的词汇多些,而银行.大厦.汽车.公园这样的词汇少些,我们就倾…

Bag-of-words model (BoW model) 最早出现在NLP和IR领域. 该模型忽略掉文本的语法和语序, 用一组无序的单词(words)来表达一段文字或一个文档. 近年来, BoW模型被广泛应用于计算机视觉中. 与应用于文本的BoW类比, 图像的特征(feature)被当作单词(Word). 引子: 应用于文本的BoW model Wikipedia[1]上给出了如下例子: John likes to watch movies. Mary likes too. John als…
