Domestic Activities Classification from Audio Recordings Using Multi-scale Dilated Depthwise Separable Convolutional Network

no code implementations9 Jun 2023 Yufei Zeng, Yanxiong Li, Zhenfeng Zhou, Ruiqi Wang, Difeng Lu

Domestic activities classification (DAC) from audio recordings aims at classifying audio recordings into pre-defined categories of domestic activities, which is an effective way for estimation of daily activities performed in home environment.

A Wideband Reconfigurable Intelligent Surface for 5G Millimeter-Wave Applications

no code implementations23 Apr 2023 Ruiqi Wang, Yiming Yang, Behrooz Makki, Atif Shamim

The measurement results demonstrate that the proposed RIS could maintain a 3 dB peak gain variation bandwidth among various array configurations within 22. 5 to 29. 5 GHz (26. 9%) and with a beam scanning capability of 50{\deg}, making this design a good candidate for 5G mm-wave applications.

A Via-less Fully Screen-Printed Reconfigurable Intelligent Surface for 5G Millimeter Wave Communication

no code implementations7 Feb 2023 Yiming Yang, Ruiqi Wang, Mohammad Vaseem, Behrooz Makki, Atif Shamim

In this paper, we propose a via-less fully screen-printed reconfigurable intelligent surface which can establish a second line-of-sight communication from 23. 5GHz to 29. 5GHz.

Divergence Results and Convergence of a Variance Reduced Version of ADAM

no code implementations11 Oct 2022 Ruiqi Wang, Diego Klabjan

Under a variance reduction assumption, we show that an ADAM-type algorithm converges, which means that it is the variance of gradients that causes the divergence of original ADAM.

Better Pseudo-label: Joint Domain-aware Label and Dual-classifier for Semi-supervised Domain Generalization

no code implementations10 Oct 2021 Ruiqi Wang, Lei Qi, Yinghuan Shi, Yang Gao

Also, considering inconsistent goals between generalization and pseudo-labeling: former prevents overfitting on all source domains while latter might overfit the unlabeled source domains for high accuracy, we employ a dual-classifier to independently perform pseudo-labeling and domain generalization in the training process.
