How to choose state number ？

[KelvinTao]

Hi, I want to know how to choose the state number. Is it automatically calculated by model ? Is there a suitable method to get a suitable state number ?

Yes, the state number is automatically determined by the model using a hierarchical Dirichlet process prior. It reflects the inherent diversity of behaviors present as well as the size of the dataset. The following sections of the FAQ in the keypoint-moseq docs may be helpful:
