Get observation of final episode of RL agent

6 views (last 30 days)
Hi everyone,
I statrted using RL toolbox three months ago, and I trained my RL agent. But as a part of my work I need to have the observation used in the final iteration of some episodes. Is there any opportunity to get the observation participated in a specific episode of RL training, or nor?
Also, it might be noticeable that I defined a custom environment matching with my problem, and both of the observation and state spaces are continuous.

Do you want to save the observations in the last time step of the final episode? Or all the observations shown in the final episode? Are you using a custom MATLAB or Simulink environment? Regardless, I think you can add some kind of counter and when you reach the desired episode #, just save what you need in a mat file.
It sounds like you can use the IsDone flag/condition to save what you need. You would still need a counter and when the max number of steps in the episode is reached, set IsDone to true and save the variables you need.
