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)

有两条道路双向两个车道,即每条路每个方向只有一个车道,两条道路十字交叉。假设车辆只能向前直行,而不允许转弯和后退。如果有4辆车几乎同时到达这个十字路口,如图(a)所示;相互交叉地停下来,如图(b),此时4辆车都将不能继续向前,这是一个典型的死锁问题。从操作系统原理的资源分配观点,如果4辆车都想驶过十字路口,那么对资源的要求如下: 向北行驶的车1需要象限a和b; 向西行驶的车2需要象限b和c; 向南行驶的车3需要象限c和d; 向东行驶的车4需要象限d和a。 clipboard.png(There are two roads with two lanes, one lane in each direction of each road and two roads intersecting. Suppose that the vehicle can only go straight ahead without allowing for turning and backing. If four vehicles arrive at the intersection almost simultaneously, as shown in Figure (a), and stop at each other's crossroads, as shown in Figure (b), then all four vehicles will not be able to move forward, which is a typical deadlock problem. From the point of view of resource allocation based on operating system principle, if all four vehicles want to cross the intersection, the resource requirements are as follows: The car that goes north needs 1 quadrants A and B. Westward driving vehicle 2 requires quadrant B and C. Car 3 to the South needs quadrant C and D. 4 of the cars to the East need quadrant D and a. Clipboard.png)
