Generate own performance vector?

hi,

I want to generate weighted F-Score based on weighted mean precision and recall of performance classification operator, I can generate the FScore with "Generate Attributes" operator, however, I would like to feed it as performance vector to the output of the optimise parameter operator, so that it optimizes for the FScore that I generated.. is that somehow possible?

    Good question, I don't you can do it in the platform but I think you can write an operator for that. We have a Perf to Data operator, maybe there's a way to write a Data to Perf operator.Β

    Hi,
    I have the exact same problem! I want to generate a F beta score and change beta according to the weight I want to put on precision or recall. And then I would like to add it to a performance vector so I can optimize it. Has anyone found a solution for this?
