Optimal Regret Exponents for Bayesian Statistical Decision Problems
Hyun-Young Park, Si-Hyeon Lee
We study finite-state finite-action Bayesian statistical decision problems. While exact error-exponent characterizations are known for several special cases, including hypothesis t…
Optimal Privacy-Utility Trade-Offs in LDP: Functional and Geometric Perspectives
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee
Local differential privacy (LDP) has emerged as a gold-standard framework for privacy-preserving data analysis. However, characterizing the optimal privacy-utility trade-off (PUT)…
Training-Free Coverless Multi-Image Steganography with Access Control
Minyeol Bae, Si-Hyeon Lee
Coverless Image Steganography (CIS) hides information without explicitly modifying a cover image, providing strong imperceptibility and inherent robustness to steganalysis. However…
Secure Communications, Sensing, and Computing Towards Next-Generation Networks
Ruiqi Liu, Beixiong Zheng, Jemin Lee +4
Next-generation wireless networks are progressing beyond conventional connectivity to incorporate emerging sensing and computing capabilities. This convergence gives rise to integr…
