Partially observed process

Q: How deeply does Optimization Algorithms: AI techniques for design, planning, and control problems cover partially observed process?

Defines states, observations, actions, policies, trajectories, rewards, and returns without deriving POMDP algorithms.

As explained in Optimization Algorithms: AI techniques for design, planning, and control problems

A partially observable Markov decision process is a sequential decision model in which the agent receives only partial observations of the underlying state.

A partially observable process models sequential decision-making when an agent sees only limited observations rather than the environment’s complete state. Fully observable environments use Markov decision processes (MDPs); partial visibility calls for a partially observable Markov decision process (POMDP). section 12.1.2

A POMDP connects the main reinforcement-learning elements:

Observations provide the partial information available to the agent at each time step. section 12.1.2
Actions come from a permissible action set and may be discrete or continuous. section 12.1.2
A policy maps states or observations to actions, while rewards and state transitions describe interaction with the environment. section 12.1.2
A trajectory records the sequence of states and actions, and expected return measures cumulative future reward. section 12.1.2

Reach the Treasure

A treasure-seeking agent must reach its goal and exit while acting from limited environmental information, illustrating why observation may replace complete state information. section 12.1.2
