Restore Buffer Overflow Attacks: Breaking Undo-Based Defense Schemes

2022 · 2022 International Conference on Information Networking (ICOIN)

Transient execution attacks have been severe security threats since such attacks exploit architectural vulnerabilities in out-of-order processors. Researchers proposed several architectural solutions to defend against transient execution attacks. By restoring the victim blocks stored temporarily …

Tempo Adaptation in Non-stationary Reinforcement Learning

2023 · arXiv (Cornell University)

We first raise and tackle a ``time synchronization'' issue between the agent and the environment in non-stationary reinforcement learning (RL), a crucial factor hindering its real-world applications. In reality, environmental changes occur over wall-clock time …

Fully Guided Neural Schrödinger bridge for Brain MR image synthesis

2025 · ArXiv.org

Multi-modal brain MRI provides essential complementary information for clinical diagnosis. However, acquiring all modalities in practice is often constrained by time and cost. To address this, various methods have been proposed to generate missing modalities …
