I’m pretty confident that k is the number of clusters. We did a lot of exercises on k-means in our study group.

I’m a bit confused; could k also refer to the number of model tests? I feel like I saw that somewhere.

I think k represents the number of clusters, but I’m not entirely sure. It feels like something we covered in class.
