K-means clustering is an unsupervised machine learning algorithm widely used for partitioning a given dataset into K groups (where K is the number of pre-determined clusters based on initial analysis). The algorithm operates on a simple principle of optimizing the within-cluster variance, commonly ...
our focus is on innovating thek-means method by redefining the distance metric in its distortion. In this study, we introduce a novelk-means clustering algorithm utilizing a distance metric derived from theℓquasi-norm with. Through an illustrative example, we showcase the ...
The K-means clustering algorithm is used to cluster the optical fiber vibration signals in the low frequency band. According to the clustering results, the ratio of the optical fiber signal eigenvalues of each production layers is obtained, and the trend of the ratio of the optical fiber signal...
A Sparse K-Means Clustering Algorithm Name: *** ID: *** K-means is a broadly used clustering method which aims to partition observations into clusters, in which each observation belongs to the cluster with the nearest mean. The popularity of K-means derives in part from its conceptual simpl...

We propose two new algorithms for clustering graphs and networks. The first, called K‑algorithm, is derived directly from the k-means algorithm. It a
We present a k-means-based clustering algorithm, which op- timizes mean square error, for given cluster sizes. A straightforward ap- plication is balanced clustering, where the sizes of each cluster are equal. In k-means assignment phase, the algorithm solves the assignment prob- lem by ...
