Hi @DoNoRe, thanks for checking out the repo. Some curves have ambiguous knee points, similar to the one from your post. Visualizing the difference curve helps me understand why the algorithm chose the point that it did. The knee point will always be selected from a local maximum in the difference curve. In the image below I changed It can be difficult to have the algorithm identify a "predetermined" knee point. I'd recommend tweaking a couple of parameters to try to get the knee point that you desire. Specifically |
