  • The last tuple wasn't an anomaly, but the current tuple is an anomaly
  • The value of the last tuple was too low, but the value of the current tuple is too high
  • The value of the last tuple was too high, but the value of the current tuple is too low
  • The distance from the normal value-area to the value of the current tuple raised in comparison to the last (also anomal) tuple at least by the value-area of the normal area (6 in the example).

Parameters

  • minValue The minimal value which is still allowed.

  • maxValue The maximum allowed value.
  • nameOfParameter Name of the attribute which should be analysed
  • sendAllAnomalies If true, all tuples which have the wrong value will be send further. If false, only tuples which show a changing situation will be send further.
  • predicate Additional predicate that needs to be true to send the anomaly. You need to deactivate 'sendAllAnomalies'.
