What does training mode do?

When I run HIPS in training mode, and it allows a process, is there a certain set of actions that now becomes allowed for that process? Or only the exact same action that took place during the training period?

As far as I can tell, when in proactive config, running HIPS in training mode will make allow rules for all the types of actions that were performed by that process.
For instance, if it modified registry keys, then it will have an allow rule to modify all registry keys, not just that particular one.
