Description: 分类是数据挖掘 、机器学习 和模式识别 中一个重要的研究领域。分类的目的是学会一个分类模型 (称作分类器)，该模型能把未知类别的数据项映射到给定类别中。目前发展较成熟的几种分类算法 如决策树、神经网络、贝叶斯方法、遗传算法等。分类具有广泛的应用，例如医学诊断、信用卡系统的信用分级、图像模式识别等。本毕业设计通过使用鸢尾属植物(IRIS)数据集，对当前数据挖掘中具有代表性的优秀分类算法进行分析和比较，总结出了各种算法的特性，为使用者选择算法或研究者改进算法提供了依据。-Classification of data mining, machine learning and pattern recognition is an important area of research. The purpose of classification is to learn a classification model (called classifier), the model can unknown types of data items mapped to a given category. Currently the more mature types of classification algorithms such as decision trees, neural networks, Bayesian methods, genetic algorithms. Classification with a wide range of applications such as medical diagnosis, credit card system, credit rating, image pattern recognition. The graduation project by using the Iris genus (IRIS) data sets, data mining has on the current outstanding representative of the analysis and comparison of classification algorithms, summed up the characteristics of various algorithms for researchers to improve the user selection algorithm or algorithm provided.

Description: 函数实现了lelief算法。（计算样本的每一个特征的分类权重，选出具有最大权重的一组特征。样本的特征就是基因）。
对权重较大的一组基因进行两两冗余分析。将相关性弱的和强相关中权重大的基因保留，即为特征基因。
已知基因表达谱数据、不同类样本的个数，自行设定分类特征的权重阈值。
对原始数据标准化的方法：（x－基因均值）/基因方差。
样本的类内类间距离采用欧氏距离。-Lelief function implements the algorithm. (Classification weight each feature samples is calculated weight of a selected set of features having the greatest weight. Characteristic is the gene sample). Of the weight of a larger set of pairwise genetic redundancy analysis. The significant correlation between weak and strong correlation in the right gene retention, that is characteristic gene. Number of known gene expression data, samples of different classes, wherein the classification set threshold own weight. Of raw data standardized methods: (x- Gene mean)/variance gene. The between-class distance class of the sample using the Euclidean distance. Platform: |
