Is it worth posting reproducibility studies As an undergraduate interested in Academia, is it worth posting your reproducibility study of a paper on arXiv and linking to it on Google scholar? Is it useful to future graduate schools? Specifically with regards Machine Learning and Computer Science..
Yes, publishing reproducibility studies is encouraged:


It helps the research community determine whether the original study is valid and reliable.
It helps other researchers or students reproduce the study themselves, in particular in order to improve or build upon it.
It benefits your reputation: people might cite it, and it will be taken into account when you apply for a position or a grant later.
Some conferences/journals in ML encourage submitting reproducibility studies, so you might even be able to get a peer-reviewed publication out if it.
