## Does the previous States store in MDP?

Let’s get mathy: The Markov Property The a of course still represents the action being taken. However, the new state depends only on the previous state. It has no dependence on the history of states in the past.

## What is role of Markov decision process in reinforcement learning?

MDP is a framework that can solve most Reinforcement Learning problems with discrete actions. With the Markov Decision Process, an agent can arrive at an optimal policy (which we’ll discuss next week) for maximum rewards over time.

## What does MDP mean?

Acronym | Definition |

## How is the Markov process of a state defined?

Formally, for a state S_t to be Markov, the probability of the next state S_ (t+1) being s’ should only be dependent on the current state S_t = s _ t, and not on the rest of the past states S₁ = s₁, S₂ = s₂, … A Markov Process is defined by (S, P) where S are the states, and P is the state-transition probability.

## How does the agent control the Markov process?

Introduction to actions elicits a notion of control over the Markov Process, i.e., previously, the state transition probability and the state rewards were more or less stochastic (random). However, now the rewards and the next state also depend on what action the agent picks. Basically, the agent can now control its own fate (to some extent).

## How does the Markov decision process work in reinforcement learning?

Mathematically, we define Markov Reward Process as : What this equation means is how much reward (Rs) we get from a particular state S [t]. This tells us the immediate reward from that particular state our agent is in. As we will see in the next story how we maximize these rewards from each state our agent is in.

The Markov chain, also known as the Markov process, consists of a sequence of states that strictly obey the Markov property; that is, the Markov chain is the probabilistic model that solely depends on the current state to predict the next state and not the previous states, that is, the future is conditionally independent of the past.
