Variants of HSMMs
Abstract
The usual HSMMs may not be appropriate in some special cases. There are variants of HSMMs proposed for those special applications. Among the variants of HSMMs, a switching HSMM allows the model parameters to be changed in different time periods. An adaptive factor HSMM allows the model parameters to be a function of time. A context-dependent HSMM lets the model parameters be determined by a given series of contextual factors. A multichannel HSMM describes multiple interacting processes. A signal model of HSMM uses an equivalent form to express an HSMM. Infinite HSMM/HDP-HSMM extends the state space to infinite. This chapter presents all these variants of HSMMs and discusses the relationships between HSMMs and ...
