WebDec 1, 2024 · k-means clustering is widely used in many fields such as data mining, machine learning, and information retrieval. In many cases, users need to cooperate to perform k-means clustering tasks. WebMay 6, 2024 · Fellus et al. propose a decentralized k-means algorithm which executes in communication rounds, and in each round nodes compute an approximation of the new centroids in a distributed manner. It is clear that both distributed and decentralized k-means can be efficiently solved using collaborative averaging as well as summarizing …
WebJan 1, 2024 · Traditional K-Means based distributed data clustering require number of clusters as input which is difficult to obtain in case of a real life application like wireless sensor network. To mitigate this issue here an Automatic Distributed K-Means (ADK-Means) algorithm is proposed. In this algorithm cluster assignment is carried out with … Webprovide any theoretical guarantee, or relate distributed PCA to k-means clustering. Here we provide a theoretical analysis, which leads to a way to set the algorithm parameters, so that we will not compromise much on the quality of the clustering obtained on the projected data.
