Continuous Spiking Graph Neural Networks

Inspired by recent spiking neural networks (SNNs), which emulate a biological inference process and provide an energy-efficient neural architecture, we incorporate the SNNs with CGNNs in a unified framework, named Continuous Spiking Graph Neural Networks (COS-GNN).

Dynamic Spiking Graph Neural Networks

no code implementations15 Dec 2023 Nan Yin, Mengzhu Wang, Zhenghan Chen, Giulia De Masi, Bin Gu, Huan Xiong

Current work often uses SNNs instead of Recurrent Neural Networks (RNNs) by using binary features instead of continuous ones for efficient training, which would overlooks graph structure information and leads to the loss of details during propagation.

A Unified Query-based Paradigm for Camouflaged Instance Segmentation

1 code implementation14 Aug 2023 Bo Dong, Jialun Pei, Rongrong Gao, Tian-Zhu Xiang, Shuo Wang, Huan Xiong

Due to the high similarity between camouflaged instances and the background, the recently proposed camouflaged instance segmentation (CIS) faces challenges in accurate localization and instance segmentation.

Rethink Depth Separation with Intra-layer Links

no code implementations11 May 2023 Feng-Lei Fan, Ze-Yu Li, Huan Xiong, Tieyong Zeng

Then, we modify the depth separation theory by showing that a shallow network with intra-layer links does not need to go as wide as before to express some hard functions constructed by a deep network.

Memory-aided Contrastive Consensus Learning for Co-salient Object Detection

2 code implementations28 Feb 2023 Peng Zheng, Jie Qin, Shuo Wang, Tian-Zhu Xiang, Huan Xiong

To learn better group consensus, we propose the Group Consensus Aggregation Module (GCAM) to abstract the common features of each image group; meanwhile, to make the consensus representation more discriminative, we introduce the Memory-based Contrastive Module (MCM), which saves and updates the consensus of images from different groups in a queue of memories.

Energy Efficient Training of SNN using Local Zeroth Order Method

no code implementations2 Feb 2023 Bhaskar Mukhoty, Velibor Bojkovic, William de Vazelhes, Giulia De Masi, Huan Xiong, Bin Gu

To circumvent the problem surrogate method uses a differentiable approximation of the Heaviside in the backward pass, while the forward pass uses the Heaviside as the spiking function.

Perturbation Diversity Certificates Robust Generalisation

no code implementations29 Sep 2021 Zhuang Qian, Shufei Zhang, Kaizhu Huang, Qiufeng Wang, Bin Gu, Huan Xiong, Xinping Yi

It is possibly due to the fact that the conventional adversarial training methods generate adversarial perturbations usually in a supervised way, so that the adversarial samples are highly biased towards the decision boundary, resulting in an inhomogeneous data distribution.

Scale-Aware Graph Neural Network for Few-Shot Semantic Segmentation

1 code implementation CVPR 2021 Guo-Sen Xie, Jie Liu, Huan Xiong, Ling Shao

However, they fail to fully leverage the high-order appearance relationships between multi-scale features among the support-query image pairs, thus leading to an inaccurate localization of the query objects.
