Targeted Physical-World Attention Attack on Deep Learning Models in Road Sign Recognition

2020 · arXiv (Cornell University)

Real world traffic sign recognition is an important step towards building autonomous vehicles, most of which highly dependent on Deep Neural Networks (DNNs). Recent studies demonstrated that DNNs are surprisingly susceptible to adversarial examples. Many …

ExClique: An Express Consensus Algorithm for High-Speed Transaction Process in Blockchains

2025 · arXiv (Cornell University)

Proof of Authority (PoA) plays a pivotal role in blockchains for reaching consensus. Clique, which selects consensus nodes to generate blocks with a pre-determined order, is the most popular implementation of PoA due to its …
