"Feature selection inside validation loop"

Dear All,

Is it possible to run feature selection inside cross validation?

I created the following process (pasted below) which I believe does exactly this.
But I'm afraid that the remember and recall of feature weights might return feature weights from the previous loop.

Best regards,

Wessel

    Hi Wessel,

    sure, this is possible. This works with Remember and Recall in principle but you actually would not need Remember and Recall at all but could use the "Through" port like in the process below.

    Cheers,
    Ingo
