What is a self state?

In machine learning, specifically in reinforcement learning, a self state refers to a state in which an agent is currently located. It represents the current environment and the agent's knowledge about it.

- In reinforcement learning, the agent typically interacts with an environment and receives rewards or penalties based on its actions.

- The self-state is the representation of the agent's internal state, which consists of its current observations, memories, and internal variables relevant to the task.

- It is the input to the agent's policy or decision-making function, determining its actions.

- The self-state evolves as the agent interacts with the environment.
