![]() Then the steady-state probability of being in state A is: For example, if the transition matrix is: The transition matrix can also be used to calculate the steady-state probabilities of a system, which is the probability of being in each state, given that the system has been in operation for a long time. Then the probability of being in state A at the next time step is 0.7, and the probability of being in state B is 0.3. For example, if the current state is A and the transition matrix is: The transition matrix is used to predict the future state of a system, given the current state. This is in contrast to a Markov process, which takes into account all previous states. In a Markov chain, the next state is determined solely by the current state, without regard for the previous states. What is a transition matrix?Ī transition matrix is a mathematical representation of the probabilities of moving from one state to another in a Markov chain. Stationary distributions are important in many settings, including reinforcement learning and Markov decision processes. This is in contrast to a non-stationary distribution, which does change over time. In AI, a stationary distribution is a probability distribution that does not change over time. ![]() For example, in a first-order Markov chain, the current state only depends on the previous state in a second-order Markov chain, the current state depends on the two previous states and so on. In a Markov chain, the order is the number of previous states that the current state depends on. This ability can be used to make decisions in real-time, such as deciding which route to take in a traffic jam, or which stock to buy or sell. The Markov chain model is a powerful tool for AI applications because it can be used to predict the future state of a system based on its current state. The model is named after Andrey Markov, who first proposed it in the early 1900s. The Markov chain model is a mathematical model that is used to predict the future state of a system based on its current state. This assumption is reasonable for many systems, such as weather patterns, stock prices, and traffic flow. The Markov chain model is based on the assumption that the future state of a system can be predicted from its current state.
