Right now I'm splitting the dataset in half to get the predictions of the first layer. I can make this configurable. You're right that the literature doesn't really support different classifiers working on different representations. I’ll take this out. On Wed, Dec 16, 2015 at 11:03 AM, Andreas M

I think stacking would be a nice contribution. Are you doing loo / cross validation to get the predictions of the first level? Otherwise this is basically "VotingClassifier" And in the "literature" version, all classifiers get the same data. We need to think about how and if we want to support

2015-12-15 Thread Dan Shiebler
Hello, I have some code and tests written for a StackingClassifier that has an sklearn-like interface and is compatible with sklearn classifiers. The classifier contains methods to easily train classifiers on different transformations of the same data and train a meta-classifier on the classifier

This paper is about using Stacking to boost the multi-classes accuracy of sentiment classification significantly: "The Importance of Neutral Examples for Learning Sentiment". I found this paper interesting and the experiment results a bit surprising. On Sun, Mar 25, 2012 at 10:28 PM, Satrajit Ghos

Hi, list I am looking for a a stacking classifier implementation. It falls into the category of ensemble classifier. I can't find it in sklearn now. But if someone are implementing one, I would be glad to try it. Thanks. -- Best Wishes Meng Xinfa
