I'm pretty sure that 2 works independently created that are the same, both own the copyright. An infringer has to have had access to the work he/she is being accused of infringing. In Katie Perry's case it was claimed because the Youtube video of the accuser was viewed 3M times on Youtube she could not say she never had access. An algorithm can't have access, so imo both parties would own the copyright (if an algorithm can own a copyright)
