Abstract
This method of configuring a device for detecting a situation from among a set of situations in which it is possible to find a physical system observed by a least one sensor, comprises the following steps: receiving (102) a training sequence corresponding to a determined situation of the physical system; determining (118) parameters of a statistical hidden Markov model recorded on the detection device and related to the determined situation, based on a prior initialization (104-116) of these parameters.The prior initialization (104-116) comprises the following steps: determining (104, 106) multiple probability distributions from the training sequence; distributing (108-114) the determined probability distributions between the hidden states of the statistical model being used; and initializing the parameters of the statistical model being used from representative probability distributions determined for each hidden state of the statistical model being used.
