sklearn学习之聚类 - 简书

Webnumpy：科学计算的基础库，包括多维数组处理、线性代数等 pandas：主要用于数据处理分析，提供了简单高效的dataframe对象，可以完成数据清洗预处理可视化 scikit-learn：基于python语言的机器学习算法库，建立在numpy、scipy、matplotlib之上，基本功能主要被分为 … Hierarchical clustering is a general family of clustering algorithms that build nested clusters by merging or splitting them successively. This hierarchy of clusters is represented as a tree (or dendrogram). The root of the tree is the unique cluster that gathers all the samples, the leaves being the clusters with only … See more Non-flat geometry clustering is useful when the clusters have a specific shape, i.e. a non-flat manifold, and the standard euclidean distance is not the right metric. This case arises in the … See more Gaussian mixture models, useful for clustering, are described in another chapter of the documentation dedicated to mixture models. KMeans can be seen as a special case of Gaussian mixture model with equal covariance … See more The algorithm can also be understood through the concept of Voronoi diagrams. First the Voronoi diagram of the points is calculated using the … See more The k-means algorithm divides a set of N samples X into K disjoint clusters C, each described by the mean μj of the samples in the cluster.
