Problem: 1. We can't find patterns in full attribute space, and patterns may only be found in smaller subspaces. 2. Pattern Trails is an interactive visual approach for the exploration of subspaces of multivariate data Related work: 1. Multivariate d…

本文的概念内容来自深入浅出设计模式一书 现实世界中的适配器(模式) 我带着一个国标插头的笔记本电脑, 来到欧洲, 想插入到欧洲标准的墙壁插座里面, 就需要用中间这个电源适配器. 面向对象的适配器 你有个老系统, 现在来了个新供应商的类, 但是它们的接口不同, 如何使用这个新供应商的类呢? 首先, 我们不想修改现有代码, 你也不能修改供应商的代码. 那么你只能写一个可以适配新供应商接口的类了: 这里, 中间的适配器实现了你的类所期待的接口, 并且可以和供应商的接口交互以便处理你的请求. 适配器可以…

Q: What is a Design Pattern? A: Design Patterns represent solutions to problems what arise when developing software within a particular context. Each pattern describes a problem which occurs over and over again in our environment, and then describes…

290. Word Pattern istringstream 是将字符串变成字符串迭代器一样,将字符串流在依次拿出,比较好的是,它不会将空格作为流,这样就实现了字符串的空格切割. C++引入了ostringstream.istringstream.stringstream这三个类,要使用他们创建对象就必须包含sstream.h头文件. istringstream类用于执行C++风格的串流的输入操作. ostringstream类用于执行C风格的串流的输出操作. strstream类同时可以支持…

We use network visualizations to look into the voting patterns in the current German parliament. I downloaded the data here and all figures can be reproduced using the R code available on Github. Missing values, invalid votes, abstention from voting…

题目: Given a pattern and a string str, find if str follows the same pattern. Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty word in str. Examples: pattern = "abba", str = "dog cat c…
