HB-net: Holistic bursting cell cluster integrated network for occluded multi-objects recognition

1 code implementation18 Oct 2023 Xudong Gao, Xiao Guang Gao, Jia Rong, Xiaowei Chen, Xiang Liao, Jun Chen

Although in high-noise settings, standard CNNs exhibit slightly greater robustness when compared to HB-net models, the models that combine the HB framework and EA mechanism achieve a comparable level of accuracy and resilience to ResNet50, despite having only three convolutional layers and approximately $1/30$ of the parameters.

Distance and Hop-wise Structures Encoding Enhanced Graph Attention Networks

no code implementations6 Dec 2021 Zhiguo Huang, Xiaowei Chen, Bojuan Wang

Numerous works have proven that existing neighbor-averaging Graph Neural Networks cannot efficiently catch structure features, and many works show that injecting structure, distance, position or spatial features can significantly improve performance of GNNs, however, injecting overall structure and distance into GNNs is an intuitive but remaining untouched idea.

Multi-layered Network Exploration via Random Walks: From Offline Optimization to Online Learning

no code implementations9 Jun 2021 Xutong Liu, Jinhang Zuo, Xiaowei Chen, Wei Chen, John C. S. Lui

For the online learning setting, neither the network structure nor the node weights are known initially.

Semantic Borrowing for Generalized Zero-Shot Learning

no code implementations30 Jan 2021 Xiaowei Chen

Generalized zero-shot learning (GZSL) is one of the most realistic but challenging problems due to the partiality of the classifier to supervised classes, especially under the class-inductive instance-inductive (CIII) training setting, where testing data are not available.
