Applications in machine learning The k-means clustering algorithm is used in almost every domain and industry. It’s typically applied to machine learning data that has few dimensions, is numeric and can be easily portioned. Researchers have integrated k-means clustering with deep learning methods...
K-means k均值聚类算法(k-means clustering algorithm)是一种迭代求解的聚类分析算法 它试图将数据集划分为K个不同的非重叠子组(簇),其中每个数据点只属于一个组 同时使得簇内数据点尽可能相似,还要尽可能保持簇之间的差异 聚类分配的质量是通过计算质心收敛后的平方误差和(sum of the squared error,SSE)来确定...
Private K-Means Clustering: Algorithms and Applications论文阅读报告 组员:黎君玉杨根张荣华 背景 大数据是一把双刃剑。一方面,我们可以通过分析用户数据来提取有价值的行为模式。例如,由附着在汽车,智能手机用户或自动驾驶汽车上的巡回传感器节点的集合生成的GPS数据可以为我们提供有关个人活动模式的重要信息(例如,他们...
As k-means clustering algorithm starts with k randomly selected centroids, it’s always recommended to use theset.seed()function in order to set a seed forR’s random number generator. The aim is to make reproducible the results, so that the reader of this article will obtain exactly the ...

(Liu et al., 2017). However, the adoption of K-means clustering algorithm for the realistic field applications in these areas still needs to be analysed in greater depth. The iterative non-convex optimization for moving the cluster’s centre in K-means clustering algorithm is suitable for the...
