how to check accuracy of k means clustering

How do you check the quality of clustering?
Assessing cluster quality and validity involves evaluating the clustering solution against specific metrics and methods, such as silhouette coefficient, elbow method, Dunn index, and Calinski-Harabasz index, to determine how well the solution fits the data and how useful it is for the intended purpose.
To do this, you can use a variety of techniques such as visualizing the data in a variety of ways to look for patterns, using a clustering algorithm to look for natural groupings in the data, and using statistical methods such as the K-means algorithm to measure the similarity between points in the data.

How do you measure clustering accuracy?

The Rand Index can be calculated using the following formula: RI=2(a+b)n(n−1).
In other words, it evaluates a share of observations for which these splits (initial and clustering results) are consistent.
The Rand Index (RI) evaluates the similarity of the two splits of the same sample.
