Linear Probing Provides Robust and Efficient Detection of Machine-Generated Text

#20 · paper · Gerrit Quaremba, Hanqi Yan, Elizabeth Black, Denny Vrandecic, Elena Simperl ·

Shows simple linear probes can detect machine-generated text efficiently and hold up better out of domain than heavier detectors.

Machine-generated text detection has struggled with domain shift and large training requirements. This paper is interesting because it argues that latent representations separate well enough for simple linear probes to outperform more elaborate detectors. If replicated, that would make detector training cheaper and easier to stress-test across domains.
