Hello,
In the cluster kmeans results inertia is not true.
For example:
- Kmeans model, k=8, intertia is 1.0e+6
- Kmeans model, k=9, intertia is 9.6e+5
I think inertia must decrease when k increase.
Hi Aslan,
You are correct, inertia usually decreases when the number of clusters k increases! And the results you show actually back up this claim, since:
k | inertia |
8 | 1e+6 = 1,000,000 |
9 | 9.6e+5 = 960,000 |
Hope this helps!
Best,
Harizo
Thanks HarizoR.
