Heterogeneous trust-aware recommender systems in social network

2017

Trust, as the basis of human interactions, has been playing an important role in addressing information sharing, experience communication, and public opinions. Trust-aware recommender systems are an effective solution to the information overload problem, especially …

On the Hamming distances of repeated-root cyclic codes of length $5p^s$

2019 · arXiv (Cornell University)

Due to the wide applications in consumer electronics, data storage systems and communication systems, cyclic codes have been an interesting research topic in coding theory. In this paper, let $p$ be a prime with $p\ge …

Distributed randomized Kaczmarz for the adversarial workers

2022 · arXiv (Cornell University)

Developing large-scale distributed methods that are robust to the presence of adversarial or corrupted workers is an important part of making such methods practical for real-world problems. Here, we propose an iterative approach that is …

Optimal Asynchronous Dynamic Policies in Energy-Efficient Data Centers

2019 · arXiv (Cornell University)

In this paper, we use a Markov decision process to find optimal asynchronous policy of an energy-efficient data center with two groups of heterogeneous servers, a finite buffer, and a fast setup process at sleep …

Controlled quantum secure direct communication with twice identity authentications based on the entanglement swapping of Bell states

2025 · Laser Physics Letters

Abstract In this paper, after quantum identity authentication is applied into controlled quantum secure direct communication (CQSDC), a CQSDC protocol with twice identity authentications is put forward based on the entanglement swapping of Bell states. …
