Railway Network Delay Evolution: A Heterogeneous Graph Neural Network Approach

no code implementations27 Mar 2023 Zhongcan Li, Ping Huang, Chao Wen, Filipe Rodrigues

This paper aims to develop a heterogeneous graph neural network (HetGNN) model, which can address different types of nodes (i. e., heterogeneous nodes), to investigate the train delay evolution on railway networks.

RGI: robust GAN-inversion for mask-free image inpainting and unsupervised pixel-wise anomaly detection

no code implementations24 Feb 2023 Shancong Mou, Xiaoyi Gu, Meng Cao, Haoping Bai, Ping Huang, Jiulong Shan, Jianjun Shi

In this paper, we propose a Robust GAN-inversion (RGI) method with a provable robustness guarantee to achieve image restoration under unknown \textit{gross} corruptions, where a small fraction of pixels are completely corrupted.

DeSTSeg: Segmentation Guided Denoising Student-Teacher for Anomaly Detection

1 code implementation CVPR 2023 Xuan Zhang, Shiyu Li, Xi Li, Ping Huang, Jiulong Shan, Ting Chen

In this study, we propose an improved model called DeSTSeg, which integrates a pre-trained teacher network, a denoising student encoder-decoder, and a segmentation network into one framework.

RIM: Reliable Influence-based Active Learning on Graphs

1 code implementation NeurIPS 2021 Wentao Zhang, Yexin Wang, Zhenbang You, Meng Cao, Ping Huang, Jiulong Shan, Zhi Yang, Bin Cui

Message passing is the core of most graph models such as Graph Convolutional Network (GCN) and Label Propagation (LP), which usually require a large number of clean labeled data to smooth out the neighborhood over the graph.

BatchQuant: Quantized-for-all Architecture Search with Robust Quantizer

no code implementations NeurIPS 2021 Haoping Bai, Meng Cao, Ping Huang, Jiulong Shan

While single-shot quantized neural architecture search enjoys flexibility in both model architecture and quantization policy, the combined search space comes with many challenges, including instability when training the weight-sharing supernet and difficulty in navigating the exponentially growing search space.
