entropy
for entropy
H = entropy(S)
this command will evaluate the entropy of S, S should be row matrix
H = entropy([X Y Z])
this command will find the joint entropy for the 3 variables
H = entropy([X,Y],[Z,W])
this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies
Please validate this function before using it

BP-and-SOM
BP（Back Propagation）网络是一种按误差逆传播算法训练的多层前馈网络，是目前应用最广泛的神经网络模型之一。
BP网络能学习和存贮大量的输入-输出模式映射关系，而无需事前揭示描述这种映射关系的数学方程。
它的学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小。BP神经网络模型拓扑结构包括输入层（input）、隐层(hide layer)和输出层(output layer)。
通过对信息的提取以及记忆，用作分类、聚类、预测等。
(BP (Back Propagation) network is a pre-press error back propagation algorithm Multilayer feedforward network, is one of the most widely used neural network model. BP network can learn and store a large amount of input- output mode mapping without prior reveal mathematical equations that describe the mapping relationship. It s learning rule is to use the steepest descent method, by reverse spread to constantly adjust the network weights and thresholds and the minimum sum of squared error of the network. BP neural network topology comprises an input layer (input), hidden layer (hide layer) and an output layer (output layer). By extracting information and memory, it is used as classification, clustering, prediction.)

K-means 和 BPSO
应用背景
虽然传统的基因选择方法已经能够取得很好的效果，选出的基因子集有利于后续样本分类，但是这些方法主要考虑数据方差和分布的相关性，从而选出的基因可解释性较差且冗余度较高。为了获得最小冗余可解释的基因子集，本文在充分考虑基因类别灵敏度 (Gene to class sensitivity,GCS) 信息和基因调控 (Gene regulation,GR) 信息的基础上，利用二进制微粒群算法(BPSO)和极限学习机(ELM)进行基因选择。
关键技术该方法提出用PSO优化K均值聚类，并在此基础上确定初始化种群，随后运用两个BPSO分别结合GCS和GR信息进行进行选择。在多个基因表达谱数据上的实验结果表明，相比BPSO-GCS-ELM和其他一些经典的基因选择方法，该方法能够选出更紧凑且分类能力更强的基因子集。
