a sample space Ω or non-empty set from which random fluctuations or outcomes ω ∈ Ω are drawn |
external states
states of the world that cause sensory states and depend on action |
sensory states
the agent's sensations that constitute a probabilistic mapping from action and external states |
action states
an agent's action that depends on its sensory and internal states |
internal states
the states of the agent that cause action and depend on sensory states |
ergodic density
a probability density function over external ψ ∈ Ψ, sensory s ∈ S, active a ∈ A and internal states λ ∈ Λ for a system denoted by m
|
variational density q(ψ|λ) an arbitrary probability density function over external states that is parametrized by internal states |
