Secret-Protected Evolution for Differentially Private Synthetic Text Generation

ICLR 2026poster

Text data has become extremely valuable on large language models (LLMs) and even lead to general artificial intelligence (AGI). A lot of high-quality text in the real world is private and cannot be freely used due to privacy concerns. Therefore, differentially private (DP) synthetic text generation…

Convergence analysis of the information matrix in Gaussian Belief Propagation

ICASSP 2017accepted

Gaussian belief propagation (BP) has been widely used for distributed estimation in large-scale networks such as the smart grid, communication networks, and social networks, where local meansurements/observations are scattered over a wide geographical area. However, the convergence of Gaussian BP is…
