WebThe Markov Switching Dynamic Regression model is a type of Hidden Markov Model that can be used to represent phenomena in which some portion of the phenomenon is directly observed while the rest of it is ‘hidden’. The hidden part is modeled using a Markov model, while the visible portion is modeled using a suitable time series regression model … WebA Markov decision process is a Markov chain in which state transitions depend on the current state and an action vector that is applied to the system. Typically, a Markov …

"WebN2 - This brief considers quantized control for finite-Time synthesis of nonlinear semi-Markov switching systems (S-MSSs) via T-S fuzzy strategy. The stochastic phenomena of structural and parametric changes are modeled by the semi-Markov process, in which the sojourn-Time (ST) is deemed to obey a non-exponential distribution.
