AuthentiGPT: Detecting Machine-Generated Text via Black-Box Language Models Denoising

no code implementations13 Nov 2023 Zhen Guo, Shangdi Yu

Under the assumption that human-written text resides outside the distribution of machine-generated text, AuthentiGPT leverages a black-box LLM to denoise input text with artificially added noise, and then semantically compares the denoised text with the original to determine if the content is machine-generated.
