OpenRIS: Democratizing reconfigurable intelligent surfaces for real-world wireless enhancements
Weicong Chen, Junjie Ai, Lin Bai +7
Wireless enhancement is critical for next-generation mobile communication systems to realize seamless connectivity, yet traditional network expansion strategies are becoming econom…
Angle-Dependent Phase Shifter Model for Reconfigurable Intelligent Surfaces: Does the Angle-Reciprocity Hold?
Weicong Chen, Lin Bai, Wankai Tang +3
The existing phase shifter models adopted for reconfigurable intelligent surfaces (RISs) have ignored the electromagnetic (EM) waves propagation behavior, thus cannot reveal practi…
CausalGuard: Conformal Inference under Graph Uncertainty
Vikash Singh, Weicong Chen, Debargha Ganguly +12
Estimating treatment effects from observational data requires choosing an adjustment set, but valid adjustment depends on an unknown causal graph. Graph misspecification can cause…
LABELING COPILOT: A Deep Research Agent for Automated Data Curation in Computer Vision
Debargha Ganguly, Sumit Kumar, Ishwar Balappanawar +6
Curating high-quality, domain-specific datasets is a major bottleneck for deploying robust vision systems, requiring complex trade-offs between data quality, diversity, and cost wh…
Multi-timescale Channel Customization for Transmission Design in RIS-assisted MIMO Systems
Weicong Chen, Chao-Kai Wen, Xiao Li +1
The performance of transmission schemes is heavily influenced by the wireless channel, which is typically considered an uncontrollable factor. However, the introduction of reconfig…
Robust Ultra-High-Dimensional Variable Selection With Correlated Structure Using Group Testing
Wanru Guo, Juan Xie, Binbin Wang +4
Background: High-dimensional genomic data exhibit strong group correlation structures that challenge conventional feature selection methods, which often assume feature independence…
