From Attack Success to Attack Severity: Counterfactual Memory Attacks on LLM Agents

Mingxi Zou, Langzhang Liang, Zhuo Wang +3

As LLM agents increasingly rely on persistent memory for long-horizon and personalized behavior, they can retain and reuse information across interactions, but this also creates a…

DARC: Disagreement-Aware Alignment via Risk-Constrained Decoding

Mingxi Zou, Jiaxiang Chen, Junfan Li +4

Preference-based alignment methods (e.g., RLHF, DPO) typically optimize a single scalar objective, implicitly averaging over heterogeneous human preferences. In practice, systemati…
