Surface EMG-Based Inter-Session/Inter-Subject Gesture Recognition by Leveraging Lightweight All-ConvNet and Transfer Learning

no code implementations13 May 2023 Md. Rabiul Islam, Daniel Massicotte, Philippe Y. Massicotte, Wei-Ping Zhu

The existing approaches employed very large and complex deep ConvNet or 2SRNN-based domain adaptation methods to approximate the distribution shift caused by these inter-session and inter-subject data variability.

Copula-Based Modeling of RIS-Assisted Communications: Outage Probability Analysis

no code implementations22 Jan 2022 Imène Trigui, Damoon Shahbaztabar, Wessam Ajib, Wei-Ping Zhu

In this letter, we exploit the concept of copula modeling to capture the non-standard dependence features that appear due to the presence of discrete phase noise.

Outage Constrained Robust Secure Beamforming in Cognitive Satellite-Aerial Networks

no code implementations13 May 2021 Bai Zhao, Min Lin, Ming Cheng, Wei-Ping Zhu, Naofal Al-Dhahir

This paper proposes a robust beamforming scheme to enhance the physical layer security (PLS) of multicast transmission in a cognitive satellite and aerial network (CSAN) operating in the millimeter wave frequency band.

TSTNN: Two-stage Transformer based Neural Network for Speech Enhancement in the Time Domain

no code implementations18 Mar 2021 Kai Wang, Bengbeng He, Wei-Ping Zhu

In this paper, we propose a transformer-based architecture, called two-stage transformer neural network (TSTNN) for end-to-end speech denoising in the time domain.

S-ConvNet: A Shallow Convolutional Neural Network Architecture for Neuromuscular Activity Recognition Using Instantaneous High-Density Surface EMG Images

no code implementations8 Jun 2019 Md. Rabiul Islam, Daniel Massicotte, Francois Nougarou, Philippe Massicotte, Wei-Ping Zhu

Without using any pre-trained models, our proposed S-ConvNet and All-ConvNet demonstrate very competitive recognition accuracy to the more complex state of the art for neuromuscular activity recognition based on instantaneous HD-sEMG images, while using a ~ 12 x smaller dataset and reducing learning parameters to a large extent.

Atomic Norm Based Localization of Far-Field and Near-Field Signals with Generalized Symmetric Arrays

no code implementations5 Dec 2017 Xiaohuan Wu, Wei-Ping Zhu, Jun Yan

Most localization methods for mixed far-field (FF) and near-field (NF) sources are based on uniform linear array (ULA) rather than sparse linear array (SLA).
