Markov Chain

여러 State를 갖는 Chain 형태의 구조

Markov chain is a model of stochastic evolution of the system captured in discrete snapshots. The

Stochastic matrix describes the probabilities with which the system transits into different state. Therefore, You can start with a messy process which is not

Stationary process but which will eventually converge to a well behaved

Stationary process which is driven by only one probability law and your process can freely visit all states (

Ergodicity) within state spaces without getting trapped in a loop.

The point is that the probability of a state at a particular time depends only on the immediately preceding state, following the Markov assumption, which is a discrete-time stochastic process.

At any point of the sequence, the marginal distribution is given by

Q. Markov Chain을 고등학생에게 설명한다면 어떤 방식이 좋을까요? Q. Markov Chain 은 머신러닝 알고리즘 중 어디에 활용이 되나요? Q. 깁스 샘플링 은 무엇인가 Q. 깁스 샘플링 은 왜 쓰는가 ? sites.google.com/site/machlearnwiki/RBM/markov-chain (제가 보려고 여기에 다시 옮겨 적어유 원문은 링크로 ! ) 마코프 체인은 마코프 성질을 지닌 이산 확률 과정이라고 합니다.
