I haven’t, no. I really wish I could somehow investigate all 3 pillars of a good watermark (Decisiveness, Invisibility, Robustness), but I couldn’t think of any way to quantify a general text watermark’s invisibility. For any given watermark you can technically rate “how invisible it is” by using an LLM’s loss function to see how different the watermarked text is from the original text, but I can’t come up with a way to generalize this. So unfortunately my analysis was only about the interplay between decisiveness and robustness.
