Hi folks
I’m struggling with about 50 features. Each feature is a double value measure and has two additional columns with the lower and upper bound. It’s a “set” of three columns (value, lower bound, upper bound).
The features are all from one product and I want to know which feature causes the faulty testing result.
What is the best way to get a boolean result for each feature as well as get an overall result with the faulty feature(s) named by name (column header). I have no idea to achieve that in Knime.
I appreciate your help and I am curious on your tipps and hints.
I used the “Column List Loop Start” node to loop over value columns.
Used a flow variable to filter the columns regarding the current feature.
Then used 2 “Column Expressions” node to create 2 columns, one showing where the fault is (exceeding upper or lower limit) and the other is a Boolean column which has a true value for healthy features and false for the faulty ones.
at the end I closed the loop and joined the columns.
