About adaptive state knowledge extraction for septic shock mortality prediction

Abstract

The early prediction of mortality is one of the unresolved tasks in intensive care medicine. This paper models medical symptoms as observations cased by transitions between hidden Markov states. Learning the underlying state transition probabilities results in a prediction probability success of about 91%. The results are discussed and put in relation to the model used. Finally, the rationales for using the model are reflected: Are there states in the septic shock data?.
