Graph Data Condensation via Self-expressive Graph Structure Reconstruction

no code implementations12 Mar 2024 Zhanyu Liu, Chaolv Zeng, Guanjie Zheng

They could not explicitly leverage the information of the original graph structure and failed to construct an interpretable graph structure for the synthetic dataset.

Dataset Condensation for Time Series Classification via Dual Domain Matching

no code implementations12 Mar 2024 Zhanyu Liu, Ke Hao, Guanjie Zheng, Yanwei Yu

Different from previous methods, our proposed framework aims to generate a condensed dataset that matches the surrogate objectives in both the time and frequency domains.

Cross-city Few-Shot Traffic Forecasting via Traffic Pattern Bank

1 code implementation17 Aug 2023 Zhanyu Liu, Guanjie Zheng, Yanwei Yu

Then, the traffic data of the data-scarce city could query the traffic pattern bank and explicit relations between them are constructed.

FDTI: Fine-grained Deep Traffic Inference with Roadnet-enriched Graph

1 code implementation19 Jun 2023 Zhanyu Liu, Chumeng Liang, Guanjie Zheng, Hua Wei

Under this setting, traffic flow is highly influenced by traffic signals and the correlation between traffic nodes is dynamic.
