WebJul 27, 2007 · Switching Linear Dynamic System (SLDS) models are a popular technique for modeling complex nonlinear dynamic systems. An SLDS can describe complex temporal patterns more concisely and accurately than an HMM by using continuous hidden states. However, the use of SLDS models in practical applications is challenging for three reasons. WebJul 1, 2002 · Bayesian estimation of a very general model class where the distribution of the observations is assumed to depend on a latent mixture or switching variable taking values in a discrete state space is discussed, e.g. finite mixture modelling, Markov switching autoregressive modelling and dynamic linear models with switching.
