Zusammenfassung:	A device (100) for and a method of determining a length of a history of instances of a first type of data are provided. The device comprises a second data set unit (104), a first data set unit (102), a first conditional entropy unit (106), a threshold unit (108), and a length determining unit (114). The first data set unit, the second data set unit and the threshold unit obtain input data. The first conditional entropy unit determines a first conditional entropy for a second data set given a first data set. The determining unit searches for a length of the relevant history by determining a smallest length for sequences of a reduced first set of data for which a second conditional entropy for the second set of data, given the reduced first set of data, is within a maximum entropy increase threshold from the first conditional entropy.
