Refined Detection for Gumbel Watermarking
arXiv CS.LG

ArXi:2603.30017v1 Announce Type: new We propose a simple detection mechanism for the Gumbel watermarking scheme proposed by Aaronson. The new mechanism is proven to be near-optimal in a problem-dependent sense among all model-agnostic watermarking schemes under the assumption that the next-token distribution is sampled i.i.d.
