What to look out for when designing an environment regarding observations?
When designing an environment, what should one look out for when designing the observation space to make the environment as easy to be learnable for an agent as possible?
E.g. make sure the markov ...

When should discretization of observations be considered?
I found some literature regarding the design of action-spaces and that e.g. a discretization of continuous actions in video-game environments can be crucial for successful learning (Action Space ...

Are multi agent or self-play environments always automatically POMDPs?
As part of my thesis, I'm working on a zero sum game with RL to train an agent.
The game is a real-time game, a derivation of pong, one could imagine playing pong with both sides being foosball rods.
...

Should I apply normalization to the observations in deep reinforcement learning?
I am new to DRL and trying to implement my custom environment. I want to know if normalization and regularization techniques are as important in RL as in Deep Learning.
In my custom environment, the ...

How do neural networks deal with inputs of different sizes that are padded in order to have them of the same size?
I am trying to create an environment for RL where the size of my input (observation space) is not fixed. As a way around it, I thought about padding the size to a maximum value and then assigning &...

Scrabble rack observation with MuZero
Currently I'm trying to implement Scrabble with MuZero.
The $15 \times 15$ game board observation (as input) is of size $27 \times15 \times15$ (26 letters + 1 wildcard) with a value of 0 or 1.
However ...

What happens when the agent faces a state that never before encountered?
I have a network with nodes and links, each of them with a certain amount of resources (that can take discrete values) at the initial state. At random time steps, a service is generated, and, based on ...

Does the order in which the features are concatenated to create the state (or observation) matter?
I'm experimenting with an RL agent that interacts with the following environment. The learning algorithm is double DQN. The neural network represents the function from state to action. It's build with ...
