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...
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 ...

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 ...
More recently,Tiwari et al. (2020)cast the problem of choosingkmedoids into a multi-arm bandit problem and solved it using the Upper Confidence Bound algorithm. This variation was faster than PAM and matched its accuracy. Conclusion The k-means clustering algorithm has several drawbacks, such as...
Recognizing the pivotal role of choosing an appropriate distance metric in designing the clustering algorithm, our focus is on innovating the k-means metho
