when we change the rules to change the weights but during the episode we don't have the reward at least we assume we only get kind of the reward at the end so we need a different uh method and the method is going to be the following right here the important things in this formula are going to be so how do we change the weights that's dependent on two quantities that appear during each time step o i and oj and these are going to be the outputs of neuron i and neuron j so how do we change the connection that's going to be dependent
