Hi,
I want to know if this repo comes from E. B. Fox and modified by Scott Niekum? Because I searched the website and found no information about this package in Scott Niekum's personal homepage or his paper. Actually, I want to reproduce Scott Niekum's experiment in one of his paper, so I need to confirm he used this package in his experiment. Any feedback is welcomed.
Thank you.

Yes, this repo was initially shared by Scott Niekum for his IJRR2015 paper-"Learning Grounded Finite-State Representations from Unstructured Demonstration". You can find the code in Scott Niekum's personal homepage by 1. Access Home page: https://www.cs.utexas.edu/~sniekum/index.php 2. Click PUBLICATIONS 3. Scroll down until the publications in 2015, and then you can find the code attached with the corresponding paper. 3. In the code page https://www.cs.utexas.edu/~sniekum/code.php, you should find the downloading link under the Other code section, named, * Matlab code* for automatic segmentation of demonstrations using the BP-AR-HMM. Hopefully, this can help you.

Thanks, it is really helpful. By the way, I noticed that there is a demo folder in your repo, which I can't find from Scott's version. Did you update the package ?

Well, probably the same purpose. I use it to segment a sequential task in the context of imitation learning. The difference is the BP-AR-HMM serves as a contrast experiment, which will be compared with another algorithm. Cause you know BP-AR-HMM is kind of the state of art performance for nonparametric segmentation, at least theoretically. How about your results? Is it good for your assembly task. I guess these methods maybe task related and more critically, it is hard to say what is a good segment. Finally, if you are interested in my work, we can contact offline.
