Hello guys,
How can i add a logic test in choosing which to keep in Removing Correlated Attributes?
Example: Removing internal correlated attributes while keeping attributes that have high correlation with one fixed attributes - Data base (n+2) which have Attribute x and n+1 intercorrelated attributes => Removing n attributes that are intercorrelated and the 1 got kept (in n+1 attributes) is the one that have highest correlation with attribute x

Thank you for your help.

    Hi @StevenDuong369,

    you have interesting operators for remove correlated attributes like RemoveCorrelatedFeatures operator. 
    if you want to create your own rules you can try  to convert the correlation matrix in a exampleset with the Matrix to Exampleset operator from Coverters Extension. Then you can create your own rules with the Filter Examples Opertaror, for example. 

    Best,
    Cesar
