Don't Trust: Verify -- Grounding LLM Quantitative Reasoning with Autoformalization

1 code implementation26 Mar 2024 Jin Peng Zhou, Charles Staats, Wenda Li, Christian Szegedy, Kilian Q. Weinberger, Yuhuai Wu

Large language models (LLM), such as Google's Minerva and OpenAI's GPT families, are becoming increasingly capable of solving mathematical quantitative reasoning problems.

REFACTOR: Learning to Extract Theorems from Proofs

1 code implementation26 Feb 2024 Jin Peng Zhou, Yuhuai Wu, Qiyang Li, Roger Grosse

With newly extracted theorems, we show that the existing proofs in the MetaMath database can be refactored.

Zero-shot Object-Level OOD Detection with Context-Aware Inpainting

no code implementations5 Feb 2024 Quang-Huy Nguyen, Jin Peng Zhou, Zhenzhen Liu, Khanh-Huyen Bui, Kilian Q. Weinberger, Dung D. Le

RONIN conditions the inpainting process with the predicted ID label, drawing the input object closer to the in-distribution domain.

Out of Distribution (OOD) Detection

Correction with Backtracking Reduces Hallucination in Summarization

no code implementations24 Oct 2023 Zhenzhen Liu, Chao Wan, Varsha Kishore, Jin Peng Zhou, Minmin Chen, Kilian Q. Weinberger

The results show that CoBa is effective and efficient in reducing hallucination, and offers great adaptability and flexibility.

Magnushammer: A Transformer-Based Approach to Premise Selection

no code implementations8 Mar 2023 Maciej Mikuła, Szymon Tworkowski, Szymon Antoniak, Bartosz Piotrowski, Albert Qiaochu Jiang, Jin Peng Zhou, Christian Szegedy, Łukasz Kuciński, Piotr Miłoś, Yuhuai Wu

By combining \method with a language-model-based automated theorem prover, we further improve the state-of-the-art proof success rate from $57. 0\%$ to $71. 0\%$ on the PISA benchmark using $4$x fewer parameters.

Unsupervised Out-of-Distribution Detection with Diffusion Inpainting

1 code implementation20 Feb 2023 Zhenzhen Liu, Jin Peng Zhou, Yufan Wang, Kilian Q. Weinberger

We present a novel approach for this task - Lift, Map, Detect (LMD) - that leverages recent advancement in diffusion models.

Learned Systems Security

no code implementations20 Dec 2022 Roei Schuster, Jin Peng Zhou, Thorsten Eisenhofer, Paul Grubbs, Nicolas Papernot

We analyze the root causes of potentially-increased attack surface in learned systems and develop a framework for identifying vulnerabilities that stem from the use of ML.

Draft, Sketch, and Prove: Guiding Formal Theorem Provers with Informal Proofs

3 code implementations21 Oct 2022 Albert Q. Jiang, Sean Welleck, Jin Peng Zhou, Wenda Li, Jiacheng Liu, Mateja Jamnik, Timothée Lacroix, Yuhuai Wu, Guillaume Lample

In this work, we introduce Draft, Sketch, and Prove (DSP), a method that maps informal proofs to formal proof sketches, and uses the sketches to guide an automated prover by directing its search to easier sub-problems.

Does Label Differential Privacy Prevent Label Inference Attacks?

1 code implementation25 Feb 2022 Ruihan Wu, Jin Peng Zhou, Kilian Q. Weinberger, Chuan Guo

Label differential privacy (label-DP) is a popular framework for training private ML models on datasets with public features and sensitive private labels.

On Attribution of Deepfakes

no code implementations20 Aug 2020 Baiwu Zhang, Jin Peng Zhou, Ilia Shumailov, Nicolas Papernot

We discuss the ethical implications of our work, identify where our technique can be used, and highlight that a more meaningful legislative framework is required for a more transparent and ethical use of generative modeling.

Noise Contrastive Estimation for Autoencoding-based One-Class Collaborative Filtering

no code implementations3 Aug 2020 Jin Peng Zhou, Ga Wu, Zheda Mai, Scott Sanner

One-class collaborative filtering (OC-CF) is a common class of recommendation problem where only the positive class is explicitly observed (e. g., purchases, clicks).
