Having issues with the "find informative projections" feature in Orange 3. In order to be able to use this feature in the scatterplots, you have to select a target variable in the "select columns". So I choose the value that I'm most interested in finding correlations to. However, whatever I choose as a target variable doesn't show up in the informative projections list as being correlated to other features in my data set. Why not?
I have a lot of features in my data and was under the impression that the "find informative projections" option finds pairs of features that seem to have a linear correlation and sorts them by which pairs are most correlated.
If that's the case, why do you need a target variable? How do I choose an appropriate target variable?
Am I misunderstanding the purpose of the "find informative projections" feature?
