摘要: A method of classifying a data record as belonging to one of a plurality of classes, the data records comprising a plurality of data samples, each sample comprising a plurality of features derived from a value sampled from a sensor signal at a point in time, the method including: defining a selection variable indicative of the temporal variation of the sensor signals within a time window; defining a selection criterion for the selection variable; comparing a value of the selection variable to the selection criterion to select an input representation for a self organising map, the map having a plurality of input and output units, and deriving an input from the data samples within the time window in accordance with the selected input representation; and applying the input to a self organising map corresponding to the selected input representation and classifying the data record based on a winning output unit of the self organising map.
