Hi David. Yeah, you could just wrap the K method from GPy. But most of the code in GPy is not needed for KPCA. Writing down the kernel yourself is probably as easy in many cases ;) Cheers, Andy On 02/03/2014 07:49 AM, David Fuchs wrote: Hi to all, I want to use KPCA with fit_inverse_transfor

[Scikit-learn-general] using GPy kernels

2014-02-02 Thread David Fuchs
Hi to all, I want to use KPCA with fit_inverse_transform=True. Question: What is the easiest way to test other kernels, aside from the ones available in the metrics package, keeping in mind that I need the pre-image (inverse) option? I noticed that GPy has a wide range of kernels and the option
