Is your feature request related to a current problem? Please describe. We need to improve our models using Change Point Detection algorithms.
Describe proposed solution You can provide an implementation of algorithms like :
- PELT: a fast offline detection algorithm::::: Killick et al.: “Optimal Detection of Changepoints With a Linear Computational Cost”, Journal of the American Statistical Association, Informa UK Limited, 2012, 107, 1590–1598 https://www.tandfonline.com/doi/abs/10.1080/01621459.2012.737745.

- Online Bayesian changepoint detection::::: Bayesian Online Changepoint Detection https://arxiv.org/abs/0710.3742
A reference implementation can be found here: https://schuetzgroup.github.io/sdt-python/changepoint.html#module-sdt.changepoint
Thanks a lot!!!
Hi @manavchoudhary, why not. However we have many other things on our backlog as well. Would you be willing to help and contribute such models?
I would also be interested in something like this. Maybe integration with https://github.com/deepcharles/ruptures would be a good way to support change point detection? (I currently don't have time to work on this myself, but if I ever do, I'll be sure to contribute it.)
