Systems and methods are provided for constructing a classification architecture for a pattern recognition classifier that determines an associated occupant class of an occupant within a vehicle. A plurality of occupant classes are defined, with at least one of the occupant classes having an associated set of subclasses ( 202 ). A hierarchy of subclass partitions is determined based on a degree of similarity between subclasses associated with a given occupant class ( 210 ). Each successive partition in the hierarchy is an immediate partition of the preceding partition. The following is then performed iteratively until a termination event occurs. A subclass partition is selected according to the determined hierarchy ( 216/230 ). The fitness of a classifier model having an architecture derived from the selected subclass partition is evaluated ( 220 ). A class separation associated with the selected subclass partition is retained when the evaluated fitness is better than that of the preceding subclass partition in the hierarchy ( 224 ).
