CommNet and BiCnet implementation in tensorflow
I'd like to use commnet at waterworld because it seems like a good decision for agents to communicate and get a reward, but why didn't it converge in the end and not as good as maddpg
Thanks for reply, I have been busy at another project last few days, recently I get spare time.
I have noticed that at comm_net, the variables of communication part(maybe along with encoder part) are not shared between critic and actor,
I don't know whether it should be like these way in regular algorithms trained by DDPG like comm_net?
At row 104, the code is ''h = tf.slice(H, [j, 0], [1, HIDDEN_VECTOR_LEN]) ''
shouldn't it be h = tf.slice(H, [0,j,0],[-1, 1, HIDDEN_VECTOR_LEN]) ?
Hi Coac, i really like your BicNet implementation! My goal is to run your BicNet implementation on an environment where every agent gets -1 reward for each time step it needs to finish the env. But there is a problem with your actor loss implementation, because the loss of the actor is defined as the prediction of the critic, the rewards needs to converges to zero if the agents performs perfect, isn't it?
loss_actor = -self.critic(state_batches, clear_action_batches).mean()
Can you explain to me why you implemented it this way? Also, is there a possibility that the reward doesn't converges to 0 when the Agents performs good (linke in the environment i mentioned above)?
