Abstract Gunrock是一种社交机器人,旨在让用户参与开放域的对话.我们使用大规模的用户交互数据来迭代地改进了我们的机器人,使其更具能力和人性化.在2018年Alexa奖的半决赛期间,我们的系统进行了40,000多次对话.我们开发了一个上下文感知的分层对话框管理器,以处理各种用户行为,例如主题切换和问题解答.此外,我们设计了一个健壮的三步自然语言理解模块,其中包括句子分割和自动语音识别(ASR)错误校正等技术.此外,我们通过添加韵律语音合成来改善系统的人像性. 1 Introdicti…

题意: n个人,开始有一个容量为k得背包,击败一个人背包可以获得一定容量或得到一个财富(放入背包内),给出击败每个人的概率,求至少击败l个人,且背包容量大于获得的总财富值的概率 分析: 状态好确定,dp[i][j][k]表示前i个人击败j个背包容量是k是的概率,求概率正推,要注意这时背包容量能为负,我们把容量都加上B. #include <map> #include <set> #include <list> #include <cmath> #includ…

初步分析:把赢了的巡回赛的a值加起来就是最后的剩余空间 这个明显的是状态转移的dp啊,然而他的状态比较骚是个数组,表示剩余空间,f(i,j,b),i表示比到第几场,j表示赢了几场,b就是里面的核心状态,总起来就是在比到第i场赢了j场时背包剩余空间b的概率,所以他们加起来一定是1,状态转移的话可以看做是在f(i,j,b)这个状态再比一场,输了转移到f(i+1,j,b),赢了转移到f(i+1,j+1,b+a[i+1])....一定要注意边界处理和初始化 #include<iostream> #in…

背景介绍 美国大选开始了,国防部要求我对两个总统候选人的票数进行统计.我首先简单的进行一次无条件查询,了解了一下表格的结构及所有数据长什么样子. select * from foo 查询到的结果令我很吃惊,我没有看到选票等信息,我看到了用户名以及用户的金额,还有选项.这个看起来很明显不是美国的总统选票而是外围赌谁能当总统的,以及投注金额.好吧,拿人钱财替人消灾.我就统计统计吧.接着我执行如下操作. select sum(prize), expect, selection from foo gro…

細節較多,自己寫的第一份半殘品,未能AC,后參考了劉老師的代碼,寫出了第二份的代碼,經過多次修改后總算AC,然而後果也很嚴重,導致代碼和劉老師極其相似,這也是我不喜歡看了參考代碼后再自己寫的緣故. 祇爲怕自己忘記,所以寫博客留檔 1:一開始沒看題,就看劉老師的描述,我以爲輸入的選手信息沒有規定格式,所以第一份寫了找第一個數字的函數來確定名字與成績的分界綫,后看(翻譯)了題目才知道對輸入是有規範的,并且udebug的隨機數據的名字用P+數字描述,讓我寫的讀取信息的一系列操作作廢了: 2:即使看描述…

目录: 写一份动人简历的九个步奏 英文简历必备的十大元素 写一份动人简历的九个步骤 写一份动人的简历可以算得上是找工作最难的部分之一,但是,通过下面九步,这件事不再那么难了. 简历定位.雇主们之所以花时间和精力来到招聘现场阅读简历.筛选人才,他们的目的就是想知道你可以为他们做什么,而不是来欣赏你的简历的文彩和笔锋,所以含糊的,笼统的毫无针对性的简历会使雇主感到茫然,也使你失去很多机会.为你的简历定位,明确你到底能干什么,最能干的是什么,如果你也有多个目标,最好写上多份不同的简历,在每一份上突出重…
