Estimation_Theory
In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by
numerical examples.

FCM+Knn
用K均值算法和C模糊算法对sonar数据和iris数据进行分类。
K均值算法是一种很常用的聚类算法,其基本思想是,通过迭代寻找K个聚类的一种划分方法,使得用这K个聚类的均值来代表各类样本是所得到的的总体误差最小。
模糊C均值(FCM)算法在K均值算法的基础上,用模糊子集代替确定子集,从而得到模糊的分类结果,即分类结果的模糊化。(Sonar data and iris data are classified by means of K mean algorithm and C fuzzy algorithm.
The K mean algorithm is a very common clustering algorithm. Its basic idea is to find a partition method of K clustering by iteration, so that the average error of the mean of the K clustering is minimized.
The fuzzy C mean (FCM) algorithm is based on the K mean algorithm. The fuzzy subset is replaced by the fuzzy subset, thus the fuzzy classification result is obtained, that is, the classification result is fuzzed.)
