Re: [scikit-learn] Nested Leave One Subject Out (LOSO) cross validation with scikit

Hi! It looks like you are using the old `sklearn.cross_validation`'s LeaveOneLabelOut cross-validator. It has been deprecated since v0.18. Use the `LeaveOneLabelOut` from `sklearn.model_selection`, that should fix your issue I think (thought I have not looked into your code in detail). HTH! On

Re: [scikit-learn] Adding samplers for intersection/Jensen-Shannon kernels

2016-12-04 Thread Valery Anisimovsky via scikit-learn
I see now. So I'll proceed with adding documentation and unit tests for those kernels to complete their support. And I don't think they're too specialized, given that many kinds of feature vectors in e.g. computer vision are in fact histograms and all of those kernels are histogram-oriented. A

[scikit-learn] Nested Leave One Subject Out (LOSO) cross validation with scikit

2016-12-04 Thread Ludovico Coletta
Dear scikit experts, I'm struggling with the implementation of a nested cross validation. My data: I have 26 subjects (13 per class) x 6670 features. I used a feature reduction algorithm (you may have heard about Boruta) to reduce the dimensionality of my data. Problems start now: I defined LOS
