Intuition
Why does partial observability create a need for communication between agents?
Concept
When is information from one agent useful to another agent?
Equation
What does this mean?
$A_{i} = X_{i} \times M_{i}$
Equation
Agent $i$ 's action can be represented as both:
- a task or environment action from $X_{i}$ ;
- a communication action from $M_{i}$ .
Communication can therefore be treated as part of the agent's decision.
Equation
What does this represent?
$m_{t}^{i} = f_{i} (o_{t}^{i})$
Equation
What does this tell us about a $b$ -bit communication channel?
$∣ M ∣ = 2^{b}$
Intuition
Why is sending more information not always better?
Equation
What does this represent?
$r_{t}^{'} = r_{t} - λ c_{t}$
Concept
How can capacity, noise, loss, range, or cost change an agent's communication strategy?
Concept
What is a learned communication protocol?
Scenario
Why can two successful communication protocols fail when agents trained with different conventions are paired?
