Prediction-Powered Risk Monitoring of Deployed Models for Detecting Harmful Distribution Shifts

ICML 2026poster

We study the problem of monitoring model performance in dynamic environments where labeled data are limited. To this end, we propose prediction-powered risk monitoring (PPRM), a semi-supervised risk-monitoring approach based on prediction-powered inference (PPI). PPRM constructs anytime-valid lower …

Learned Image Transmission with Hierarchical Variational Autoencoder

AAAI 2025technical

In this paper, we introduce an innovative hierarchical joint source-channel coding (HJSCC) framework for image transmission, utilizing a hierarchical variational autoencoder (VAE). Our approach leverages a combination of bottom-up and top-down paths at the transmitter to autoregressively generate mu…

A penalty-BSUM approach for rate optimization in full-duplex MIMO relay networks with relay processing delay

ICASSP 2016accepted

This paper studies joint source transmit beamforming and relay amplification matrix design to achieve rate maximization for full-duplex (FD) MIMO amplify-and-forward (AF) relay systems with consideration of relay processing delay (RPD). The problem is difficult to solve due mainly to the self-interf…

Joint transceiver designs for secure communications over MIMO relay

ICASSP 2016accepted

This paper addresses the transceiver design problem for secure downlink communications over a multiple-input multiple-output (MIMO) relay system in the presence of multiple eavesdroppers. A new algorithm based on alternating optimization (AO) is first proposed to maximize the signal-to-noise ratio (…
