There are definitely API questions that I also just discusses with Dan. There are some thing that we could improve, but I think the solutions depend a lot on if we want to do kernel engineering or not. My thinking was that this part is probably the most controversial one, so this is what I asked about.
I am not sure how useful our current implementation is. I have not met a person that uses it. That might be caused by the interface and missing documentation more than by the fact that we don't have custom kernels, though. I don't think we want to add a HODLR solver (hierarchical off-diagonal low-rank solver). It you want that, you should probably install gorge ;) What I think would be great to have is gradient based optimization of the kernel parameters, and a way to do grid-search using data likelihood (not sure if that is currently supported). For the API, the naming is somewhat non-standard, it is not super clear what the parameters mean, and it is also not super clear whether the kernel-parameters will be optimized for a given parameters setting.
