Thread: Training of Stacking

  1. #1

    Default Training of Stacking

    Hello.

    I am trying to use Stacking to combine two classifiers (actually regression models). What I really want to do is train the two regression models on one set of data, then train the stacking meta classifier on different data, but using the regression coefficients learned from the first dataset.

    The bottom line - Is it possible to give pre-trained models to Stacking and train the meta model on their output using a fresh dataset?

    Thanks in advance.

    I'm afraid that isn't possible at present. You'd have to modify the Stacking classifier. Vote allows for serialised models to be loaded, so you could look at how that is implemented when changing Stacking.

    Cheers,
    Mark.
