Can We Enhance the Quality of Mobile Crowdsensing Data Without Ground Truth?

1 code implementation29 May 2024 Jiajie Li, Bo Gu, Shimin Gong, Zhou Su, Mohsen Guizani

Given sensing data submitted by MUs, PRBTD can eliminate the data with heavy noise and identify malicious MUs with high accuracy.

xMLP: Revolutionizing Private Inference with Exclusive Square Activation

no code implementations12 Mar 2024 Jiajie Li, JinJun Xiong

However, the use of non-linear activations such as ReLU in DNNs can lead to impractically high PI latency in existing PI systems, as ReLU requires the use of costly MPC computations, such as Garbled Circuits.

AI Agent as Urban Planner: Steering Stakeholder Dynamics in Urban Planning via Consensus-based Multi-Agent Reinforcement Learning

no code implementations25 Oct 2023 Kejiang Qian, Lingjun Mao, Xin Liang, Yimin Ding, Jin Gao, Xinran Wei, Ziyi Guo, Jiajie Li

By integrating Multi-Agent Reinforcement Learning, our framework ensures that participatory urban planning decisions are more dynamic and adaptive to evolving community needs and provides a robust platform for automating complex real-world urban planning processes.

Extensible and Efficient Proxy for Neural Architecture Search

no code implementations ICCV 2023 Yuhong Li, Jiajie Li, Cong Hao, Pan Li, JinJun Xiong, Deming Chen

We further propose a Discrete Proxy Search (DPS) method to find the optimized training settings for Eproxy with only a handful of benchmarked architectures on the target tasks.

Analysis and Optimization of GNN-Based Recommender Systems on Persistent Memory

no code implementations25 Jul 2022 Yuwei Hu, Jiajie Li, Zhongming Yu, Zhiru Zhang

To understand whether persistent memory is a good fit for GNNRecSys training, we perform an in-depth characterization of GNNRecSys workloads and a comprehensive analysis of their performance on a persistent memory device, namely, Intel Optane.
