Equal Path Cost, Unequal Output Effects: Understanding Perturbation Propagation in Diffusion Models

Diffusion models have achieved remarkable success in generative modeling, with their sampling procedures routinely modified to control generation and improve efficiency. These modifications introduce perturbations along the sampling trajectory, raising a central question: how do such perturbations affect generated outp...

GSBF: Gaussian Splatting for Environment-Aware Beamforming

A 3D Gaussian splatting for environment-aware beamforming (GSBF) pipeline based on multi-modal data, which characterizes the environment through a persistent 3D Gaussian representation, which consistently outperforms baselines such as exhaustive beam alignment (EBA) with lower latency.

Task-Oriented Communication with Hybrid-Precision Models

A hybrid-precision task-oriented communication framework for edge inference to holistically balance communication, on-device computation, and utility is proposed and confirmed that this design achieves an optimal trade-off among communication efficiency, on-device computational cost, and inference accuracy.
