density factor implementation about st_dbscan HOT 2 CLOSED

Hello,
yes, the density factor as described in the paper [1] is currently not implemented. However, we assume that if you use the fit_frame_split as described in the paper [2], that to some degree different densities over time will also be supported. However, not within the same partitioned frame. A potential solution for this is to simply replace the algorithm in a fork with the HDBSCAN algorithm (link) which is able to capture different densities.

I hope this helps you.

Cheers,
Eren

Awesome thanks for the pointers, I am reading them.
