Towards trustworthy agentic AI: a comprehensive survey of safety, robustness, privacy, and system security

Jinhu Qi, Muzhi Li, Jiahong Liu +9

Agentic AI systems -- Large Language Models (LLMs) augmented with planning, tool use, memory, and long-horizon interactions -- can execute complex tasks autonomously, but their mul…

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…

Patterns of Closeness and Abstractness in Colexifications: The Case of Indigenous Languages in the Americas

Yiyi Chen, Johannes Bjerva

Colexification refers to linguistic phenomena where multiple concepts (meanings) are expressed by the same lexical form, such as polysemy or homophony. Colexifications have been fo…
