Uncertainty, Calibration, and Membership Inference Attacks: An Information-Theoretic Perspective

no code implementations16 Feb 2024 Meiyi Zhu, Caili Guo, Chunyan Feng, Osvaldo Simeone

We derive bounds on the advantage of an MIA adversary with the aim of offering insights into the impact of uncertainty and calibration on the effectiveness of MIAs.

Boundary-Aware Proposal Generation Method for Temporal Action Localization

no code implementations25 Sep 2023 Hao Zhang, Chunyan Feng, Jiahui Yang, Zheng Li, Caili Guo

More importantly, few works consider the background frames that are similar to action frames in pixels but dissimilar in semantics, which also leads to inaccurate temporal boundaries.

Information Bottleneck-Inspired Type Based Multiple Access for Remote Estimation in IoT Systems

no code implementations19 Dec 2022 Meiyi Zhu, Chunyan Feng, Caili Guo, Nan Jiang, Osvaldo Simeone

Type-based multiple access (TBMA) is a semantics-aware multiple access protocol for remote inference.

Joint LED Selection and Precoding Optimization for Multiple-User Multiple-Cell VLC Systems

no code implementations29 Aug 2021 Yang Yang, Yujie Yang, Mingzhe Chen, Chunyan Feng, Hailun Xia, Shuguang Cui, H. Vincent Poor

First, a MU-MC-VLC system model is established, and then a sum-rate maximization problem under dimming level and illumination uniformity constraints is formulated.

Power Efficient LED Placement Algorithm for Indoor Visible Light Communication

no code implementations17 Jun 2020 Yang Yang, Zhiyu Zhu, Caili Guo, Chunyan Feng

Due to the interactions among LEDs and the illumination uniformity constraint, the formulated problem is complex and non-convex.

A Novel Received Signal Strength Assisted Perspective-three-Point Algorithm for Indoor Visible Light Positioning

no code implementations21 May 2020 Lin Bai, Yang Yang, Chunyan Feng, Caili Guo

The basic idea of R-P3P is to joint visual and strength information to estimate the receiver position using 3 LEDs regardless of the LEDs' orientations.
