0. 聚类步骤 为了完成一个聚类任务,必须遵循以下步骤: 特征选择:合适的选择特征,尽可能多的包含任务关心的信息,使得信息冗余减少和最小化是主要目标: 近邻测度:用于定量测量两个特征向量如何"相似"或"不相似",这里需要注意让选中的特征都具有相同的近邻性,不能让某个或某些特征占支配地位: 聚类准则:依赖于专家的判断,可以通过代价函数或者其他规则表示: 聚类算法:用于揭示数据集的聚类结构: 结果验证:验证聚类算法结果的正确性,通常使用逼近检验: 结果判定:应用领域的专…

Introduction to Deep Neural Networks Neural networks are a set of algorithms, modeled loosely after the human brain, that are designed to recognize patterns. They interpret sensory data through a kind of machine perception, labeling or clustering raw…
目录: 1.问题描述 2.问题转化 3.划分准则 4.总结 1.问题描述 谱聚类(Spectral Clustering, SC)是一种基于图论的聚类方法——将带权无向图划分为两个或两个以上的最优子图(sub-Graph),使子图内部尽量相似,而子图间距离尽量距离较远,以达到常见的聚类的目的. 对于图的相关定义如下: 对于无向图G = (V,E),V表示顶点集合,即样本集合,即一个顶点为一个样本:E表示边集合. 设样本数为n,即顶点数为n. 权重矩阵:W,为n*n的矩阵,其值wi,j为各边的权值…
