On the differential spectrum of a class of power functions over finite fields
2020 · arXiv (Cornell University)
Differential uniformity is a significant concept in cryptography as it quantifies the degree of security of S-boxes respect to differential attacks. Power functions of the form $F(x)=x^d$ with low differential uniformity have been extensively studied …

Adaptive Gradient Coding
2021 · IEEE/ACM Transactions on Networking
This paper focuses on mitigating the impact of stragglers in distributed learning system. Unlike the existing results designated for a fixed number of stragglers, we develop a new scheme calledAdaptive Gradient Coding (AGC)with flexible communication …

New Constructions of Optimal Linear Codes From Simplicial Complexes
2023 · IEEE Transactions on Information Theory
In this paper, we construct a large family of projective linear codes over${\mathbb F}_{q}$from the general simplicial complexes of${\mathbb F}_{q}^{m}$via the defining-set construction, which generalizes the results of [IEEE Trans. Inf. Theory 66(11):6762-6773, 2020]. The …

Pre-gated MoE: An Algorithm-System Co-Design for Fast and Scalable Mixture-of-Expert Inference
2024
Large language models (LLMs) based on transformers have made significant strides in recent years, the success of which is driven by scaling up their model size. Despite their high algorithmic performance, the computational and memory …

On the Effectiveness of Task-oriented Digital Semantic Communication System
2025
Task-oriented digital semantic communication systems utilize neural networks to extract and transmit taskrelevant features, which significantly improves the communication efficiency compared to traditional communication systems. These systems also ensure compatibility with modern digital communication frameworks, …
