WebJun 19, 2024 · Sklearn will just assign some random values to the cluster in case there is an empty cluster apparently. In the link you provide, they state that it's not chosen at random btw: A problem with k-means is that one or more clusters can be empty. However, this problem is accounted for in the current k-means implementation in scikit-learn.
