Heterogeneous graph neural networks (HGNNs) have been blossoming in recent years, but the unique data processing and evaluation setups used by each work obstruct a full understanding of their advancements. In this work, we present systematical reproduction 12 HGNNs using official codes, datasets, settings, hyperparameters, revealing surprising findings about progress HGNNs. We find that simple homogeneous GNNs, e.g., GCN GAT, are largely underestimated due to improper settings. GAT with...

Sign language is a visual that uses hand gesture, change of shape and track information to express meaning, the main communication tool for people with hearing impairment. recognition can improve problem number who need use sign large but popularity poor, provide more convenient way study, work life Hand locating methods generally be divided into traditional deep learning methods. In recent years, brilliant achievements in field computer vision, it has been proved method based on many...

A numerical analysis of two-conductor transmission line with a rectangular notch in the dielectric between strips is presented. Three media integral equations are derived and solved for charge distributions. The decoupling such coupled microstrip lines investigated asymmetric conductors. It found that coupling two conducting can be reduced significantly by removing material which has shape. For best decoupling, width should as wide possible but depth have an optimum somewhere base...

Abstract. In spread spectrum induced polarization (SSIP) data processing, attenuation of background noise from the observed is essential step that improves signal-to-noise ratio (SNR) SSIP data. The time-domain spectral based on pseudorandom sequence (TSIP) algorithm has been proposed to improve SNR these However, signal processing in still a challenging problem. We propose an enhanced correlation identification (ECI) attenuate noise. this algorithm, cross-correlation matching method helpful...
