Hi,
I'm using DDPG agent for my RL application with Matlab 2022a version.
I want to take action between 0 and 1 value. To do this, i use SigmoidLayer function at the final layer of the action. However, it exceed the 0-1 boundry. I also tried to use tanh with
scalingLayer(Scale=0.5,Bias=0.5);
,but it exceed the boundry again. How it can be possible?
Meanwhile, i also tried to use
actInfo = rlNumericSpec([1 1],LowerLimit=0,UpperLimit=1);
to limit action, yes it limits the action value but it doesn't scale it. it just act as a saturation block (like putting a saturation block in simulink in front of the action output). So, with this way, the RL works wrong.
How can achive to take action between 0 and 1?
