once per so after the episode is done you're going to change these capital constants right here including the eta which is the learning rate these things right here these are per step so this is each step gives you a different oi and oj and then you'll adjust the weight based on that you'll see that these constants here they are per weight so for each weight in this neural network we learn a separate rule of how to update that particular weight so the algorithm can it can basically decide for a particular weight you can
