Source, git Heap is a data structure that can fundamentally change the performance of fairly common algorithms in Computer Science. The heap data structure is called a heap because it satisfies the heap property. The heap property states, that if P i…

论文笔记(2):A fast learning algorithm for deep belief nets. 这几天继续学习一篇论文,Hinton的A Fast Learning Algorithm for Deep Belief Nets.这篇论文一开始读起来是相当费劲的,学习了好几天才了解了相关的背景,慢慢的思路也开始清晰起来.DBN算法就是Wake-Sleep算法+RBM,但是论文对Wake-Sleep算法解释特别少.可能还要学习Wake-Sleep和RBM相关的的知识才能慢慢理解,今天…

排序算法的介绍 排序也称排序算法 (Sort Algorithm),排序是将一组数据,依指定的顺序进行排列的过程. 排序的分类 1) 内部排序: 指将需要处理的所有数据都加载 到内部存储器(内存)中进行排序. 2) 外部排序法:数据量过大,无法全部加载到内 存中,需要借助外部存储(文件等)进行 排序. 常见的排序算法分类 算法的时间复杂度 度量一个程序(算法)执行时间的两种方法 1.事后统计的方法这种方法可行, 但是有两个问题:一是要想对设计的算法的运行性能进行评测,需要实际运行该程序: 二是所…

$2016$长城信息杯中国大学生程序设计竞赛中南邀请赛$H$题 排序,二分. 对$a$数组,$b$数组从小到大进行排序. 统计每一个$a[i]$作为较大值的时候与$b[i]$对答案的贡献.反过来再统计以$b[i]$为较大值时与$a[i]$对答案的贡献. 以前者举例说明: 观察这个:$⌊\sqrt {|a[i] - b[j]|}⌋ $,按照题目中给出的范围,这个东西最大只有$1000$. 也就是说,我们在计算一个$a[i]$与$b[j]$对答案的贡献时候,不用从$1$到$m$枚举$j$,因为肯定是…

For example we have the array like this: [, , , , , ] First step is using Counting sort for last digit, in our example is: [, , , 233] [, , , , , ] Then sort according to the last digit: [, , , , , ] Then using second last digit to the sort: [, , , ,…

Insertion sort is a very intuitive algorithm as humans use this pattern naturally when sorting cards in our hands. In this lesson, using TypeScript / Javascript, we’ll cover how to implement this algorithm, why this algorithm gets its name, and the c…
