WebDec 31, 2024 · 1. Random Walks. The simple random walk is an extremely simple example of a random walk. The first state is 0, then you jump from 0 to 1 with probability 0.5 and jump from 0 to -1 with probability 0.5. Image made by me using Power Point. Then you do the same thing with x_1, x_2, …, x_n. You consider S_n to be the state at time n. http://papers.neurips.cc/paper/1217-clustering-sequences-with-hidden-markov-models.pdf

WebAbstract. Motivated by the computational difficulty of analyzing very large Markov chains, we define a notion of clusters in (not necessarily reversible) Markov chains, and explore the possibility of analyzing a cluster “in vitro,” without regard to the remainder of the chain. We estimate the stationary probabilities of the states in the ... WebDec 27, 2024 · This paper considers cluster detection in Block Markov Chains (BMCs). These Markov chains are characterized by a block structure in their transition matrix. More precisely, the n possible states are divided into a finite number of K groups or clusters, such that states in the same cluster exhibit the same transition rates to other states.
