Wireless Resource Allocation with Collaborative Distributed and Centralized DRL under Control Channel Attacks

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Wanchun Liu, Teng Joon Lim, , | Summary: In this paper, we consider a wireless resource allocation problem in a cyber-physical system (CPS) where the control channel, carrying resource allocation commands, is subjected to denial-of-service (DoS) attacks. We propose a novel concept of collaborative distributed […]

SAM Decoding: Speculative Decoding via Suffix Automaton

Kavli Affiliate: Ke Wang | First 5 Authors: Yuxuan Hu, Ke Wang, Xiaokang Zhang, Fanjin Zhang, Cuiping Li | Summary: Large Language Models (LLMs) have revolutionized natural language processing by unifying tasks into text generation, yet their large parameter sizes and autoregressive nature limit inference speed. SAM-Decoding addresses this by introducing a novel retrieval-based speculative […]

SPARS3R: Semantic Prior Alignment and Regularization for Sparse 3D Reconstruction

Kavli Affiliate: Cheng Peng | First 5 Authors: Yutao Tang, Yuxiang Guo, Deming Li, Cheng Peng, | Summary: Recent efforts in Gaussian-Splat-based Novel View Synthesis can achieve photorealistic rendering; however, such capability is limited in sparse-view scenarios due to sparse initialization and over-fitting floaters. Recent progress in depth estimation and alignment can provide dense point […]

Ultrafast optical control of charge orders in kagome metals

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yu-Ping Lin, Vidya Madhavan, Joel E. Moore, , | Summary: We show that ultrafast optical pump pulses provide effective control over charge orders in the kagome metals $A$V$_3$Sb$_5$ with $A=$ K, Rb, and Cs. Starting from the real charge density waves (rCDWs) at the $p$-type Van […]
