In data mining, various methods of clustering algorithms are used to group data objects based on their similarities or dissimilarities. These algorithms can be broadly classified into several types, each with its own characteristics and underlying principles. Let’s explore some of the commonly used ...

A number of recent and popular subspace clustering algorithms were then evaluated for their performance on the evaluation data set. As not all these algorithms are capable of producing overlapping clustering, a number of different evaluation measures were employed. We then modified the best performing...

During this work, several experiments were thoroughly conducted to reinforce the superiority of the proposed approach, specifically the site clustering algorithm compared to previous similar algorithms [7]. Five data allocation scenarios were considered in this work, three of them were replication-based ...
[1,2]. Traditional methods for clustering or community detection, such as K-means and the Leiden algorithm, typically rely only on gene expression data and disregard spatial information, often resulting in spatial domains that lack spatial continuity. To address this issue, various algorithms have ...
Besides the algorithms we present comprehensive discussion about representation of documents, calculation of similarity between documents and evaluation of clusters quality.doi:10.2478/v10177-011-0036-5Tarczynski1Department of Applied Informatics, Warsaw University of Life Sciences, ul.

When analyzing a data set, we need a way to accurately measure the performance of differentclustering algorithms; we may want to contrast the solutions of two algorithms, or see how close a clustering result is to an expected solution. In this article, we will explore some of the metrics th...

Document clustering algorithms are widely used in web searching engines to produce results relevant to a query. An example of practical use of those techniques are Yahoo! hierarchies of documents [1]. Another application of document clustering is browsing which is defined as searching session without...
