The novelty itself does not feel ground breaking due to this. The paper is also lacking in presentation. I can't see people outside a small community to follow this paper through without significant difficulties. I think the main ideas could be nicely summarised in one or two paragraphs but it is currently a pain to extract these; the notation is guesswork and will frustrate a reader who is not from the field or wants to go into details. There is no theory to support the density estimation point they make and the covariance approximation bounds are also not super significant since they make strong assumptions and the bounds seem to be not very tight. Also the link to paper [1] needs to be pointed out clearly with a proper discussion. On the plus side is Table 1 with the experimental results which seem promising.
