Multimodal Unlearning Across Vision, Language, Video, and Audio: Survey of Methods, Datasets, and Benchmarks

Nobin Sarwar, Shubhashis Roy Dipta, Zheyuan Liu +1

With the growing adoption of VLMs, DMs, LLMs, and AFMs, these multimodal foundation models can inadvertently encode sensitive, copyrighted, biased, or unsafe cross-modal associatio…

Outcome Rewards Do Not Guarantee Verifiable or Causally Important Reasoning

Qinan Yu, Alexa Tartaglini, Peter Hase +2

Reinforcement Learning from Verifiable Rewards (RLVR) on chain-of-thought reasoning has become a standard part of language model post-training recipes. A common assumption is that…

Are language models rational? The case of coherence norms and belief revision

Thomas Hofweber, Peter Hase, Elias Stengel-Eskin +1

Do norms of rationality apply to machine learning models, in particular language models? In this paper we investigate this question by focusing on a special subset of rational norm…

Unlearning Sensitive Information in Multimodal LLMs: Benchmark and Attack-Defense Evaluation

Vaidehi Patil, Yi-Lin Sung, Peter Hase +3

LLMs trained on massive datasets may inadvertently acquire sensitive information such as personal details and potentially harmful content. This risk is further heightened in multim…

System-1.x: Learning to Balance Fast and Slow Planning with Language Models

Swarnadeep Saha, Archiki Prasad, Justin Chih-Yao Chen +3

Language models can be used to solve long-horizon planning problems in two distinct modes: a fast 'System-1' mode, directly generating plans without any explicit search or backtrac…

Teaching Models to Balance Resisting and Accepting Persuasion

Elias Stengel-Eskin, Peter Hase, Mohit Bansal

Large language models (LLMs) are susceptible to persuasion, which can pose risks when models are faced with an adversarial interlocutor. We take a first step towards defending mode…
