Hello, I am using the bank-k.arff dataset for cluster analysis in Weka.
However, the dataset appears to be not ideal for cluster analysis. When using algorithms like EM, k-means, and cobweb. The result does not show trends. Classes to cluster evaluations yields unhelpful result. For instance, when using region as the class:

Most of the graphs are like this, which does not yield helpful results.
In contrast, the iris dataset:

Am I doing it incorrectly? I am new in this field of study.
