Characterizing Memorization in Diffusion Language Models: Generalized Extraction and Sampling Effects

Xiaoyu Luo, Wenrui Yu, Qiongxiu Li +1

Autoregressive language models (ARMs) have been shown to memorize and occasionally reproduce training data verbatim, raising concerns about privacy and copyright liability. Diffusi…

APEX: Probing Neural Networks via Activation Perturbation

Tao Ren, Xiaoyu Luo, Qiongxiu Li

Prior work on probing neural networks primarily relies on input-space analysis or parameter perturbation, both of which face fundamental limitations in accessing structural informa…

Semantic Leakage from Image Embeddings

Yiyi Chen, Qiongkai Xu, Desmond Elliott +2

Image embeddings are generally assumed to pose limited privacy risk. We challenge this assumption by formalizing semantic leakage as the ability to recover semantic structures from…

Do LLMs Really Memorize Personally Identifiable Information? Revisiting PII Leakage with a Cue-Controlled Memorization Framework

Xiaoyu Luo, Yiyi Chen, Qiongxiu Li +1

Large Language Models (LLMs) have been reported to "leak" Personally Identifiable Information (PII), with successful PII reconstruction often interpreted as evidence of memorizatio…

Large Language Models are Easily Confused: A Quantitative Metric, Security Implications and Typological Analysis

Yiyi Chen, Qiongxiu Li, Russa Biswas +1

Language Confusion is a phenomenon where Large Language Models (LLMs) generate text that is neither in the desired language, nor in a contextually appropriate language. This phenom…
