Detect a change in prediction in sequence in a cycle

Hello guys,

I face a problem that, I am sure, should be very easy to overcome, but that is out of my understanding of Knime -_-

Basically, I have a list of dates, name and a “prediction” that is calculated previously, that should allow me to detect a cycle of 3 steps that is repeating.

for each sequence I want to use the first change of the prediction, and I actually don’t know how to manage that ( I tried with rank, I think the solution will be a loop but I don’t find how) Processing: Detect change in the prediction.xlsx…
