The Spark distributed computing platform has emerged as...
聚类分析(Cluster Analysis)又称群分析,是根据“物以类聚”的道理,对样品或指标进行分类的一种多元统计分析方法,它们讨论的对象是大量的样品,要求能合理地按各自的特性来进行合理的分类,没有任何模式可供参考或依循,即是在没有先验知识的情况下进行的。聚类分析起源于分类学,在古老的分类学中,人们主要依靠经验和专...
The description of the algorithm can be defined as: Hierarchical Cluster Algorithm——note by ksy 1.1 Distance Calculation The choice of an appropriate metric will influence the shape of the clusters, as one element may be close to another according to one distance and farther away according to ...
They represent a powerful technique for machine learning on unsupervised data. An algorithm built and designed for a specific type of cluster model will usually fail when set to work on a data set containing a very different kind of cluster model. The common thread in all clustering algorithms ...

You can split the data for training and evaluation and choose the model framework and algorithm to build and evaluate the model. Save the model to HDFS You can save the model to HDFS by calling the python function in the hi_core_utils library by using the following call: %%spark -...
This simulation experiment motivates us to develop a stronger machine-learning prediction model to address the performance issue of the pre-copy approach. Based on the feature selection Algorithm 1, we selected four relevant input features: (Virtual Machine size (VM\(\_\)Size), Page Dirty Rate ...
This study presents a machine learning approach based on the C5.0 decision tree (DT) model and the K-means cluster algorithm to produce a regional landslide susceptibility map. Yanchang County, a typical landslide-prone area located in northwestern China, was taken as the area of interest to ...
