accuracy of k means clustering in r

PDF	Accuracy of Data Cluster Using Modify K-Mean Algorithm by Local Data clustering requires accuracy and consistency to provide unbiased results One of the most used methods is K-Means algorithm although it still has a fairly

How do you check Kmeans accuracy?
To see the accuracy of clustering process by using K-Means clustering method then calculated the square error value (SE) of each data in cluster 2.
The value of square error is calculated by squaring the difference of the quality score or GPA of each student with the value of centroid cluster 2.
What is accuracy in clustering?
Homogeneity, completeness, V-measure
Therefore, h evaluates whether each cluster is composed of the same class objects, and c measures how well the same class objects fit the clusters.
These metrics are not symmetric.
Both lie in the [0,1] range, and values closer to 1 indicate more accurate clustering results.
The most widely used clustering algorithms are as follows:
The most widely used clustering algorithms are as follows:
K-Means Algorithm. Mean-Shift Algorithm. DBSCAN Algorithm. Expectation-Maximization Clustering using Gaussian Mixture Models. Agglomerative Hierarchical Algorithm. Divisive Hierarchical Algorithm.

How can you improve the accuracy of k-means clustering?

K-means clustering algorithm can be significantly improved by using a better initialization technique, and by repeating (re-starting) the algorithm.
When the data has overlapping clusters, k-means can improve the results of the initialization technique.
