说明：  数据挖掘中计算KL距离在matlab环境下的代码(KL distance calculations in data mining environment in matlab code)

此文件夹包含了无线传感器网络中的几个经典模型leach,HEED, 分簇算法(This folder contains several classic models of wireless sensor network leach, HEED, clustering algorithm)

说明：  对UKF进行改进，采用最小偏度采样减少采样点数量，并结合实际状态方程和测量方程直接进行线性运算。改进后的UKF对蛇形机动目标的跟踪效果明显优于EKF(the mini-skewness sampling is adopted to reduce the number of sampling points, and the linear operation is carried out directly combining with the actual state equation and measurement equation. The experimental results show that the improved UKF has a better tracking effect on snake-like maneuvering targets than EKF)

利用Tikhonov正则化实现的超分辨率图像序列的重建，效果还好(Use Tikhonov regularization to achieve super-resolution image sequence reconstruction, better results)
