reinforcement learning system has to consider to maximize reward in this unknown future so again it behaves this basic setup where you have one week on network which gets in the video and the speech and whatever and it's executing actions and is trying to maximize reward so there is no teacher who tells it what to do at which point in time and then there's the other network which is just predicting what's going to happen if I do that then and that could be an LCM Network and it allows to look back all the way to make better predictions
