Careful at Estimation and Bold at Exploration

no code implementations22 Aug 2023 Xing Chen, Yijun Liu, Zhaogeng Liu, Hechang Chen, Hengshuai Yao, Yi Chang

In prior work, it has been shown that policy-based exploration is beneficial for continuous action space in deterministic policy reinforcement learning(DPRL).

LMD: A Learnable Mask Network to Detect Adversarial Examples for Speaker Verification

no code implementations2 Nov 2022 Xing Chen, Jie Wang, Xiao-Lei Zhang, Wei-Qiang Zhang, Kunde Yang

It utilizes score variation as an indicator to detect adversarial examples, where the score variation is the absolute discrepancy between the ASV scores of an original audio recording and its transformed audio synthesized from its masked complex spectrogram.

ResSFL: A Resistance Transfer Framework for Defending Model Inversion Attack in Split Federated Learning

1 code implementation CVPR 2022 Jingtao Li, Adnan Siraj Rakin, Xing Chen, Zhezhi He, Deliang Fan, Chaitali Chakrabarti

While such a scheme helps reduce the computational load at the client end, it opens itself to reconstruction of raw data from intermediate activation by the server.

Forecasting the outcome of spintronic experiments with Neural Ordinary Differential Equations

1 code implementation23 Jul 2021 Xing Chen, Flavio Abreu Araujo, Mathieu Riou, Jacob Torrejon, Dafiné Ravelosona, Wang Kang, Weisheng Zhao, Julie Grollier, Damien Querlioz

Here we show that a dynamical neural network, trained on a minimal amount of data, can predict the behavior of spintronic devices with high accuracy and an extremely efficient simulation time, compared to the micromagnetic simulations that are usually employed to model them.

Tsformer: Time series Transformer for tourism demand forecasting

no code implementations22 Jul 2021 Siyuan Yi, Xing Chen, Chuanming Tang

Based on the Transformer, we proposed a time series Transformer (Tsformer) with Encoder-Decoder architecture for tourism demand forecasting.

Communication and Computation Reduction for Split Learning using Asynchronous Training

no code implementations20 Jul 2021 Xing Chen, Jingtao Li, Chaitali Chakrabarti

An added benefit of the proposed communication reduction method is that the computations at the client side are reduced due to reduction in the number of client model updates.

Phase Noise and Frequency Accuracy in Crystal-less Wireless Edge Nodes

no code implementations23 May 2021 Xing Chen, David D Wentzloff

This paper presents a fundamental analysis connecting phase noise and long-term frequency accuracy of oscillators and explores the possibilities and limitations in crystal-less frequency calibration for wireless edge nodes from a noise-impact perspective.

Revenue and Energy Efficiency-Driven Delay Constrained Computing Task Offloading and Resource Allocation in a Vehicular Edge Computing Network: A Deep Reinforcement Learning Approach

no code implementations16 Oct 2020 Xinyu Huang, Lijun He, Xing Chen, Liejun Wang, Fan Li

In this paper, we propose a joint task type and vehicle speed-aware task offloading and resource allocation strategy to decrease the vehicl's energy cost for executing tasks and increase the revenue of the vehicle for processing tasks within the delay constraint.
