Hi..

I am newbie,
I would like to ask regarding Stacking method in Rapidminer.
So what I want to do  is making  stacking by using decision tree and naive bayes as base learner and for  meta learner I want to use bagging with decision tree in inner process.
For validation I  use 10 fold cross validation but I want to get performance result per each fold beside overall result.
More or less the scheme is as this


This is my design

Kindly please advice is my design correct for above purpose (design & data attached) ?,  and is it possible to display/store testing example process per each fold ? any comment highly appreciate.

Thank you in advance.

    Like Lionel, I am a bit confused about your desired setup.
    Stacking and bagging are two different approaches to ensemble modeling.  Bagging builds multiple independent models using the same base learner (think random forest built from underlying decision trees) and Stacking uses a master model to decide between different underlying models depending on local performance.  Vote is simpler than both of those and allows you to use multiple models everywhere and then just combine their predictions.  Your picture appears to depict the Vote approach.
    Also Naive Bayes is a very "generalized" model with no tuning parameters and is not likely to vary significantly from subset to subset and is not usually used in any kind of bagging approach.
    Finally, why do you want the performance for each fold separately in any case?  Is your dataset very small and you anticipate large potential deviation in performance from fold to fold?  Looking at fold specific performance is not going to help you compare or evaluate the individual learners you are using in the ensemble.

    Thank you very much @Telcontar120 and @lionelderkrikor for the advice and comments, also thank you for the implementation files, it is very helpful.

    First please ignore the schematic image that I sent.

    Actually my idea is kind of experiment, which I could describe like this (please give advice / correction):

    - The main ensemble method that I want to use is stacking which in my understanding is a combination of several basic methods / base learner that each method will produce the model and their respective results (all method are using same dataset).

    - Then the results of each basic model will be used as input for the next method (meta learner).

    - For the meta-learner, I want to use another ensemble method, in this case is bagging which in my understanding is method that will make different sets of input data  and use it to teach same algorithm  several times and then predict the final answer via simple majority voting.

    - I don’t know if what I have described can be simplified by using voting or exactly it is voting itself, but what I would like to ask, is it possible to make such of design like I describe without using "ready to use" voting operator :)  ? But surely for this I will also try for using voting as comparison.

    - The validation method that I want to use here is k-fold cross validation. I need performance results for each fold and overall, and if possible i want to display example input data for meta-learner part per each fold because there is requirement for me to display every detail of the process (kind of proof of concept).

    Could you give advice how to mix Stacking + Bagging correctly in rapidminer?
    or Is my last design i have sent correct ?

    Thank you.
