Localization in Multipath Environments via Active Sensing with Reconfigurable Intelligent Surfaces
Yinghan Li, Wei Yu
This letter investigates an uplink pilot-based wireless indoor localization problem in a multipath environment for a single-input single-output (SISO) narrowband communication syst…
Active Sensing for Reciprocal MIMO Channels
Tao Jiang, Wei Yu
This paper addresses the design of transmit precoder and receive combiner matrices to support independent data streams over a time-division duplex (TDD) point-to-point…
Transfer Learning with Reconstruction Loss
Wei Cui, Wei Yu
In most applications of utilizing neural networks for mathematical optimization, a dedicated model is trained for each specific optimization objective. However, in many scenarios,…
Reinforcement Learning with Non-Cumulative Objective
Wei Cui, Wei Yu
In reinforcement learning, the objective is almost always defined as a \emph{cumulative} function over the rewards along the process. However, there are many optimal control and re…
