Enhancing Real-World Complex Network Representations with Hyperedge Augmentation

no code implementations20 Feb 2024 Xiangyu Zhao, Zehui Li, Mingzhu Shen, Guy-Bart Stan, Pietro Liò, Yiren Zhao

These methods cannot fully address the complexities of real-world large-scale networks that often involve higher-order node relations beyond only being pairwise.

DiscDiff: Latent Diffusion Model for DNA Sequence Generation

no code implementations8 Feb 2024 Zehui Li, Yuhao Ni, William A V Beardall, Guoxuan Xia, Akashaditya Das, Guy-Bart Stan, Yiren Zhao

This paper introduces a novel framework for DNA sequence generation, comprising two key components: DiscDiff, a Latent Diffusion Model (LDM) tailored for generating discrete DNA sequences, and Absorb-Escape, a post-training algorithm designed to refine these sequences.

Latent Diffusion Model for DNA Sequence Generation

1 code implementation9 Oct 2023 Zehui Li, Yuhao Ni, Tim August B. Huygelen, Akashaditya Das, Guoxuan Xia, Guy-Bart Stan, Yiren Zhao

On the other hand, Diffusion Models are a promising new class of generative models that are not burdened with these problems, enabling them to reach the state-of-the-art in domains such as image generation.

Hybrid Graph: A Unified Graph Representation with Datasets and Benchmarks for Complex Graphs

no code implementations8 Jun 2023 Zehui Li, Xiangyu Zhao, Mingzhu Shen, Guy-Bart Stan, Pietro Liò, Yiren Zhao

Additionally, though many Graph Neural Networks (GNNs) have been proposed for representation learning on higher-order graphs, they are usually only evaluated on simple graph datasets.
