Detectability prediction of hidden Markov models with cluttered observation sequences

ICASSP 2016accepted

There is good reason to model an asymmetric threat (a structured action such as a terrorist attack) as an hmm whose observations are cluttered. Recently a Bernoulli filter was presented that can process cluttered observations ("transactions") and is capable of detecting if there is an HMM present, a…

A Bernoulli filter approach to detection and estimation of hidden Markov models using cluttered observation sequences

ICASSP 2015accepted

Hidden Markov Models (HMMs) are powerful statistical techniques with many applications, and in this paper they are used for modeling asymmetric threats. The observations generated by such HMMs are generally cluttered with observations that are not related to the HMM. In this paper a Bernoulli filter…
