此时,我们需要将 A[j] 与已经排序完成的 subarray A[1 .. j-1]进行对比,所以,t_j = jforj=2,3, ...,n。 \displaystyle \sum_{j=2}^n j = \frac{n(n+1)}{2} -1 and\displaystyle \sum_{j=2}^n (j-1) = \frac{n(n-1)}{2} 代入可得 \begin{aligned} T(n)=& c_{1} n+...
讲座内容 个人决策往往会出错或有偏。在人工智能时代,算法为个人决策提供了富有价值的参考。但是有两个新的问题出现:有的人会推翻基于机器学习预测的决策建议;机器学习的预测可能因为人的行为决策偏误而生成更偏误的信息。如何更好地结合行为经济学和人工智能来指导...
publicclassSummary{publicstaticvoidmain(String[]args){int sum=0,n=100;// 执行1次for(int i=1;i<101;i++){// 执行n+1次sum+=i;// 执行n次}System.out.println(sum);// 执行1次// 时间复杂度 1 + (n+1) + n + 1 = 2n + 3 ---> 忽略常量 ---> O(n)// 1 + 2 + 3 + 4...
Bug1: 错误原因:该异常表示,当前对客户端的响应已经结束,不能在响应结束后再次响应if(){} if(){} if(){}进行了多次重复判断,应该if(){}else{}使用,避免重复响应判断,正确代码如下: Bug2: 这通常是由于不经action转发到jsp页面。这个时候,原先访问jsp页面的请求路径就要换成相应的Action路径了。 ubuntu20.04...

1. 先来回顾一下矩阵乘法 2. 矩阵乘法的时间复杂度是? O(n3),一共有n2个元素,每个元素需要n次乘法和n次加法。 3. 那我们来试试用divide and conquer 也就是矩阵分块乘法 但是这样时间复杂度并没有降低,依然是O(n3) 4. 看来divide and conquer也不是随便的divide啊,那怎么办呢? Strassen的方法可以把...
This paper provides some test cases, called circuits, for the evaluation of Gaussian likelihood maximization algorithms of the cointegrated vector autoregressive model. Both I(1) and I(2) models are considered. The performance of algorithms is compared f

1. Supervised Learning Input data is called training data and has a known label or result such as spam/not-spam or a stock price at a time. A model is prepared through a training process in which it is required to make predictions and is corrected when those predictions are wrong. The ...
