Can We Transfer Noise Patterns? A Multi-environment Spectrum Analysis Model Using Generated Cases

1 code implementation2 Aug 2023 Haiwen Du, Zheng Ju, Yu An, Honghui Du, Dongjie Zhu, Zhaoshuo Tian, Aonghus Lawlor, Ruihai Dong

To make the analysis model applicable to more environments, we propose a noise patterns transferring model, which takes the spectrum of standard water samples in different environments as cases and learns the differences in their noise patterns, thus enabling noise patterns to transfer to unknown samples.

SCAI: A Spectral data Classification framework with Adaptive Inference for the IoT platform

no code implementations24 Jun 2022 Yundong Sun, Dongjie Zhu, Haiwen Du, Yansong Wang, Zhaoshuo Tian

To address the above issues, we propose a Spectral data Classification framework with Adaptive Inference.

Motifs-based Recommender System via Hypergraph Convolution and Contrastive Learning

1 code implementation2 Sep 2021 Yundong Sun, Dongjie Zhu, Haiwen Du, Zhaoshuo Tian

Based on this, we also propose a hierarchical self-supervised learning model, which realizes two levels of self-supervised learning within and between channels, which improves the ability of self-supervised tasks to autonomously mine different levels of potential information.

MHNF: Multi-hop Heterogeneous Neighborhood information Fusion graph representation learning

1 code implementation17 Jun 2021 Yundong Sun, Dongjie Zhu, Haiwen Du, Zhaoshuo Tian

Finally, a hierarchical semantic attention fusion model (HSAF) is constructed, which can efficiently integrate different-hop and different-path neighborhood information.
