| Sep 22, 2021 at 20:11 | comment | added | Ben | @ttnphns, it's still not clear. Say I run k-means three times on a 2-d dataset, each time generating two centers: trial1:{(1.5, 0.1), (2.3, 1.1)}, trail2:{(0.4, 0.1), (3.1, 1.7)}, trial3:{(0.9, 1.5), (2.0, 2.0)}. What are the "average" centers here? | |
| Sep 22, 2021 at 19:58 | comment | added | ttnphns | @Ben, as usual. Average their coordinates by each of the features. | |
| Sep 22, 2021 at 16:00 | comment | added | Ben | How exactly does one "average the cluster centres of those runs"? | |

| Nov 6, 2019 at 13:10 | comment | added | kamilazdybal | @ttnphns thanks for helpful answer! I've a question about the sensitivity to object order - do you perhaps know any paper when this was showed/studied? | |
