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…

See What I See, Know What I Think: Dense Latent Communication Across Heterogeneous Agents

Siyi Chen, Xiaoyan Zhang, Meng Wu +7

Multi-agent systems communicate mostly through text, paying a lossy and expensive decode and re-encode cost. KV-cache communication is a promising alternative, yet most prior work…

Unlearning Isn't Invisible: Detecting Unlearning Traces in LLMs from Model Outputs

Yiwei Chen, Soumyadeep Pal, Yimeng Zhang +2

Machine unlearning (MU) for large language models (LLMs), commonly referred to as LLM unlearning, seeks to remove specific undesirable data or knowledge from a trained model, while…

Leak@: Unlearning Does Not Make LLMs Forget Under Probabilistic Decoding

Hadi Reisizadeh, Jiajun Ruan, Yiwei Chen +3

Unlearning in large language models (LLMs) is critical for regulatory compliance and for building ethical generative AI systems that avoid producing private, toxic, illegal, or cop…

PrivUn: Unveiling Latent Ripple Effects and Shallow Forgetting in Privacy Unlearning

Xiaoyi Chen, Haoyuan Wang, Siyuan Tang +4

Large language models (LLMs) often memorize private information during training, raising serious privacy concerns. While machine unlearning has emerged as a promising solution, its…

Humanline: Online Alignment as Perceptual Loss

Sijia Liu, Niklas Muennighoff, Kawin Ethayarajh

Online alignment (e.g., GRPO) is generally more performant than offline alignment (e.g., DPO) -- but why? Drawing on prospect theory from behavioral economics, we propose a human-c…
