协同区间偏最小二乘 siPLS算法是 N rgaard等对其提出 的 iPLS方法的改进, 其基本算法步骤如下:(1)对原始谱图进行 预处理;(2)在全谱范围内建立全局偏最小二乘模型, 即上节的 模型;(3)在整个光谱区间采用 iPLS建立多个等窗口宽度的子 区间, 假设为 n个;(4)在每个子区间上建立偏最小二乘法模型, 即可得到 n个局部模型;(5)以交叉验证时的均方根误差 RMSE 值为各模型的精度衡量标准, 比较全光谱模型和各局部模型的 精度;(6)组合精度最高的局部子区间为新的回归区间;再在新 的回归区间建立 siPLS模型(Cooperative interval partial least squares (siPLS) algorithm is proposed by N rgaard et al. The improvements of the iPLS method are as follows: (1) the original spectrogram is performed. Preprocessing; (2) establishing a global partial least squares model in the full spectrum, that is, the upper part of the model. Model; (3) use iPLS to establish multiple equal window widths in the whole spectral interval. The interval is assumed to be n; (4) a partial least squares model is established on each sub interval. N local models can be obtained; (5) the root mean square error of cross validation is RMSE The values are the accuracy criteria of each model, and the comparison between the full spectral model and the local models is made. (6) the local interval with the highest combined precision is a new regression interval; and then new. The establishment of siPLS model in the regression interval)

C#俄罗斯方块游戏源文件，一款经典的益智游戏，儿时曾为之痴迷、上瘾，不上瘾的估计都是好学生哦。这款游戏用C#写出后简单测试一就发上来了，在以前版本的基础上修改的，运行调试截图如上图所示。

设计一个名为Account类。这个类包含： （1）一个名为id的int型数据域，表示账户的身份号（默认值为0）。 （2）一个名为balance的double型数据域，表示账户余额（默认值为0）。 （3）一个名为annualInterestRate的double型数据域，保存当前年利率（默认值为0）。 （4）一个无实参构造函数，创建一个默认账户。 （5）id、balance和annualInterestRate的访问器和更改器函数。 （6）一个名为getMonthlyInterestRate（）的函数，返回月利率。 （7）一个名为withDraw的函数，从账户中支取指定金额。 （8）一个名为deposit的函数，向账户中存入指定金额。 画出类的UML图，实现类。编写一个测试程序，它创建一个Account对象，其ID为1122，账户余额为20000，年利率为4.5 。使用withDraw函数取出2500美元，使用deposit函数存入3000美元，然后输出账户余额、月利率和账户创建时间。(Design a class named Account. This class includes: (a) a named data type int id field that indicates the account identification number (default is 0). (2) a double-called balance of data fields, which means that the account balance (default is 0). (3) a double type named annualInterestRate of data fields, save the current interest rate (default is 0). (4) a no-argument constructor creates a default account. (5) id, balance and annualInterestRate access control and change control functions. (6) a named getMonthlyInterestRate () function returns a monthly rate. (7) a function named withDraw, drawn from the account specified amount. (8) a function called deposit to the account into a designated amount. Draw a UML class diagram, the implementation class. Write a test program that creates an Account object, its ID is 1122, the account balance is 20,000, an interest rate of 4.5 . Use withDraw function out $ 2,500, $ 3,000 deposit with deposit function, and then outputs the account balance, m)
