As the original labels and the output labels of the K-means algorithm may be different, I am wondering how to find the accuracy. I am using MATLAB kmeans inbuilt library function.
Accuracy is not commonly used in unsupervised algorithms.
The problem is that the clustering algorithm does not produce classed, but "1", "2", "3" etc.
The usual evaluation would be to use ARI, Rand (which is similar to accuracy
