There are an enormous number of papers like this. I wrote a paper accelerating a small CNN classifier on FPGA and when I compared against the previous SOTA GPU implementation and the numbers were way off from the paper. I did a git blame on their repo and found that after the paper was published they deleted the lines that short-circuited eval if the sample was all 0 (which much of their synthetic data was ¯\_(ツ)_/¯).
