### TD3 Retraining from simple to complex environment

I have a robotic environment for cable robots in Unity. I am training a TD3 agent for a robot reaching task where cable lengths are the control inputs and [current cables, robot position, target ...

### Why is my agent stuck on the same action in my Twin Delayed Deep Deterministic Policy Gradient (TD3) program?

I've been tirelessly converting a reinforcement learning program from Python to JavaScript using TensorFlow.js that is running Twin Delayed Deep Deterministic Policy Gradient (TD3). I'm just trying to ...

### Can action be dominated by state features in actor-critic algorithms?

I have a case where my state consists of relatively large number of features, e.g. 50, whereas my action size is 1. I wonder whether my state features dominate the action in my critic network. I ...

### If we have a working reward function, would adding another action have a significant effect on the agent performance if task remains the same?

If we have a working reward function, providing the desired behavior and optimal policy in a continuous action/state-space problem, would adding another action significantly affect the possible ...

### Which is the best RL algo for continuous states but discrete action spaces problem

I am trying to train an AI with an environment where the states are continuous but the actions are discrete, that means I can not apply DDPG or TD3. Can someone please help to let know what should be ...

### TD3 sticking to end values [closed]

I am using TD3 on a custom gym environment, but the problem is that the action values stick to the end. Sticking to the end values makes reward negative, to be positive it must find action values ...

### Training a RL agent using different data at each episode

I am training a RL agent whose state is composed of two numbers, ranging between 4 ~ 16 and 0 ~ 360. The action is continuous and between 0~90. In real life, the states can be any I am training a TD3 ...
