ı am using cross validation and try to measure the performance of model. I need both classification and binomial performance results but I do not know now to combine them. 

Could you please help me ?

    Another way is to connect the performance output of one operator to the input of another performance operator. This creates a combined performance output. All the performance operators allow you to do this.  Then you don't even need the Multiply operator.

    Hi,
    Just because i ran into this: Are there more people around who want to change the main criterion of a performance vector after building it like @Telcontar120 described it? I ran into this like 3 times and i am close to add a new operator to Toolbox.

    There is a 3 line groovy solution though.

    Till I saw @Telcontar120 solution, I am not aware that we can do this way. This is useful.

    @mschmitz an operator sounds useful but also not a problem that personally I have faced very often in this setup---but sometimes in optimization scenarios it is also useful to be able to change the main performance criterion.
