1. A method comprising:
collecting, during a first vehicle stage, sensor data from a first set of sensors associated with a first seat within a vehicle, the first vehicle stage designating a first vehicle ignition state and gear state;
aggregating outputs of each sensor of the first set of sensors associated with the first seat to calculate a probability of life within the first seat during the first vehicle stage;
comparing the probability of life within the first seat to a threshold;
issuing a life preservation action in response to the probability of life within the first seat exceeding the threshold;
collecting feedback regarding whether life is present within the first seat of the vehicle during the first vehicle stage;
comparing the feedback to the probability of life within the first seat during the first vehicle stage; and
adjusting, based on the comparison between the feedback and the probability of life, a weight of at least one sensor output used to calculate the probability of life within the first seat during the first vehicle stage.
