WebJun 8, 2015 · 1. As I understand it, the sklearn approach does allow you to run CV on multivariate data, but you can only specify one bandwidth, so it is applied in all dimensions. You could run this on data normalised by the standard deviation in each dimension - but it will still just be a single scaling parameter for the bandwidth.
