This operator learns deviation of (each point of a) sequence. The sequence needs a counter so that the operator can distinguish multiple sequences and the values within a sequence. The operator uses the online-algorithm of the DeviationLearn operator.

Parameters

• parameterAttribute Name of the attribute which should be analysed
• sequencesToLearn The number of (correct) curves to learn from. The first x sequences will define the perfect sequence the others are compared to. If set to 0, the operator will not stop to learn (learn infinity sequences). Default is 0.
• GROUP_BY To group the tuples
• fastGrouping Use hash code instead of tuple compare to create group. Potentially unsafe!
