Be like a Goldfish, Don't Memorize! Mitigating Memorization in Generative LLMs

NeurIPS 2024poster

Large language models can memorize and repeat their training data, causing privacy and copyright risks. To mitigate memorization, we introduce a subtle modification to the next-token training objective that we call the goldfish loss. During training, a randomly sampled subsets of tokens are excluded…

Spotting LLMs With Binoculars: Zero-Shot Detection of Machine-Generated Text

ICML 2024poster

Detecting text generated by modern large language models is thought to be hard, as both LLMs and humans can exhibit a wide range of complex behaviors. However, we find that a score based on contrasting two closely related language models is highly accurate at separating human-generated and machine-g…

Canary in a Coalmine: Better Membership Inference with Ensembled Adversarial Queries

ICLR 2023top-25%

As industrial applications are increasingly automated by machine learning models, enforcing personal data ownership and intellectual property rights requires tracing training data back to their rightful owners. Membership inference algorithms approach this problem by using statistical techniques to…

Cold Diffusion: Inverting Arbitrary Image Transforms Without Noise

NeurIPS 2023poster

Standard diffusion models involve an image transform -- adding Gaussian noise -- and an image restoration operator that inverts this degradation. We observe that the generative behavior of diffusion models is not strongly dependent on the choice of image degradation, and in fact, an entire family…

Plug-In Inversion: Model-Agnostic Inversion for Vision with Data Augmentations

ICML 2022spotlight

Existing techniques for model inversion typically rely on hard-to-tune regularizers, such as total variation or feature regularization, which must be individually calibrated for each network in order to produce adequate images. In this work, we introduce Plug-In Inversion, which relies on a simple s…
