1: The theoretical analysis in Theorem 1 is unclear and weak. It is unclear that what the error bound in Theorem 1 means. The authors need to analyze and compare the theoretical results to other comparable methods.
2: The title is ambiguous and may lead to inappropriate reviewers.
3: I see no code attached to this submission, which makes me a bit concerned about reproducibility.
