.ml-state

The .ml-state index is the place where ML keeps the internal information about the statistical models that have been learned for a specific dataset, plus additional logistical information. This index is not meant to be understandable by a user—it is the backend algorithms of ML that will read and write entries in this index.

Information in the .ml-state index is compressed and is a small fraction of the size of the raw data that the ML jobs are analyzing.
