OrchJail introduces an orchestration-guided fuzzing framework to systematically jailbreak tool-calling text-to-image agents by exploiting unsafe multi-step tool-orchestration patterns.
This paper proposes IOHMM-BO, a method using a high-order input-output hidden Markov model with Bayesian optimization for predictive dynamic power management in 5G NR user equipment, achieving 43% energy saving with low computational overhead.
This paper introduces HiFuzz, a hierarchical reinforcement learning framework for processor verification that replaces mutation with a structured generation process and integrates coverage reward mechanism and semantic-aware basic block encoder.
