7.7 Design an algorithm to find the kth number such that the only prime factors are 3,5, and 7. 这道题跟之前LeetCode的那道Ugly Number II 丑陋数之二基本没有啥区别,具体讲解可参见那篇,代码如下: class Solution { public: int getKthMagicNumber(int k) { vector<, ); , i5 = , i7 = ; while (re…

Among all the factors of a positive integer N, there may exist several consecutive numbers. For example, 630 can be factored as 3*5*6*7, where 5, 6, and 7 are the three consecutive numbers. Now given any positive N, you are supposed to find the maxim…

Talk is cheap, I show you the code 第一章的作业主要是关于PGM的因子操作.实际上,因子是整个概率图的核心.对于有向图而言,因子对应的是CPD(条件分布):对无向图而言,因子对应的是势函数.总而言之,因子是一个映射,将随机变量空间映射到实数空间.因子表现的是对变量之间关系的一种设计.每个因子都编码了一定的信息. 因子的数据结构: phi = struct('var', [3 1 2], 'card', [2 2 2], 'val', ones(1, 8)); 在…

一.什么是factors? 类似于function,将一个自变量空间投影到新空间.这个自变量空间叫做scope. 二.例子 如概率论中的联合分布,就是将不同变量值的组合映射到一个概率,概率和为1. 三.几种操作(factor operation)的介绍 1.乘积 2.边缘化 3.缩减 四.总结(为何引入factor?) 1.对于定义高维空间的分布具有关键意义: 2.包括了概率分布的基本操作.…
