Big Data Clustering: A Comparative Study On Various Clustering AlgorithmsG Ashok Kumar
However, it fails to perform well for big data due to huge time complexity. For such scenarios parallelization is a better approach. Mapreduce is a popular programming model which enables parallel processing in a distributed environment. But, most of the clustering algorithms are not "naturally ...
The DBSCAN algorithm is a prevalent method of density-based clustering algorithms, the most important feature of which is the ability to detect arbitrary shapes and varied clusters and noise data. Nevertheless, this algorithm faces a number of challenges, including failure to find clusters of varied...

Clustering is a process of creating groups of similar objects. Clustering algorithms are categorized into five major categories namely, Partitioning techniques, Hierarchical techniques, Density Based techniques, Grid Based techniques and Model based techniques. Partitioning techniques are the simplest techniques...

Unlike clustering algorithms such as k-means clustering, which have randomness in the initial steps, the agglomerative hierarchical clustering algorithm considers every data point at every iteration. This algorithm has been used in disciplines such as physiology (Ray et al., 2020; Steiger et al., ...
Clustering data into three clusters: Miscarriage (M = 0), Probable Miscarriage (PM = 1) and No Miscarriage (NM = 2). Reaching a good accuracy of 99% using Silhouette method, which is a good metric to validate experiment using clustering algorithms. ...
Clustering algorithms In the big data age, traditional clustering algorithms will become even more limited than before because they typically require that all the data be in the same format and be loaded into the same machine so as to find some useful things from the whole data. Although the ...
