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

A theoretical framework to investigate perturbation propagation is developed, combining dynamical analysis of the sampling process with an information-theoretic characterization of output responses, and a response identity is derived that connects the propagation and accumulation of local perturbations with the informa...

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.
