Reviews: Stein Variational Gradient Descent With Matrix-Valued Kernels

This has clarified some of my comments, and thus I have increased my score by one level. However, a negative aspect from the author response was the excuse given for the absence of a comparison against SVN; "the results we obtained were much worse than our methods and baselines, and hence did not investigate it further". To me this seems like a very obvious thing to include and discuss in the paper, lending strong support to the new method, so I am a bit suspicious about why it wasn't included. I hope the authors will include it in the revised manuscript, if accepted. Another reviewer commented on the lack of wall-time comparison, and again I feel that the authors did not give a valid excuse for omitting this information from the manuscript (the reader can, I think, be trusted to adjust for different computational setups and hardware when interpreting the wall-time data).
