KNN
K最邻近密度估计技术是一种分类方法,不是聚类方法。
不是最优方法,实践中比较流行。
通俗但不一定易懂的规则是:
1.计算待分类数据和不同类中每一个数据的距离(欧氏或马氏)。
2.选出最小的前K数据个距离,这里用到选择排序法。
3.对比这前K个距离,找出K个数据中包含最多的是那个类的数据,即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method.
It is not the best method, but it is popular in practice.
Popular but not necessarily understandable rule is:
1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov).
2. select the minimum distance from the previous K data, where the choice sorting method is used.
3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

This MATLAB software implements the denoising algorithm (the Probabilistic
Patch-Based filter) for images damaged by multiplicative Nakagami-Rayleigh
noise as presented in: Iterative Weighted Maximum Likelihood Denoising
with Probabilistic Patch-Based Weights , C-A. Deledalle, L. Denis and
F. Tupin, IEEE Trans. on Image Processing, vol. 18, no. 12, pp. 2661-2672,
December 2009. It also corresponds to the NL-SAR filter: A non-local
approach for SAR and interferometric SAR denoising , C-A. Deledalle,
Florence Tupin and Loï c Denis, in the proceedings of IGARSS, Honolulu,
Hawaii, USA, July 2010.
