Adversarial stylometry is a way to analyze the "style" of a writing sample by comparing it to other writing samples. It works by searching for differences or patterns in the words and sentence structure used. For example, if we compared two writing samples, we could tell if one was written by an adult and one was written by a child because they would have different word choices and sentence structures. Adversarial stylometry can also be used to determine if two pieces of writing were likely written by the same person.
