On a hypergraph probabilistic graphical model

no code implementations20 Nov 2018 Mohammad Ali Javidian, Linyuan Lu, Marco Valtorta, Zhiyu Wang

We propose a directed acyclic hypergraph framework for a probabilistic graphical model that we call Bayesian hypergraphs.

Saturation problems in the Ramsey theory of graphs, posets and point sets

no code implementations13 Apr 2020 Gábor Damásdi, Balázs Keszegh, David Malec, Casey Tompkins, Zhiyu Wang, Oscar Zamora

We prove a saturation version of the Erd\H{o}s-Szekeres theorem about monotone subsequences and saturation versions of some Ramsey-type theorems on graphs and Dilworth-type theorems on posets.

Image restoration quality assessment based on regional differential information entropy

no code implementations8 Jul 2021 Zhiyu Wang, Jiayan Zhuang, Ningyuan Xu, Sichao Ye, Jiangjian Xiao, Chengbin Peng

With the development of image recovery models, especially those based on adversarial and perceptual losses, the detailed texture portions of images are being recovered more naturally. However, these restored images are similar but not identical in detail texture to their reference images. With traditional image quality assessment methods, results with better subjective perceived quality often score lower in objective scoring. Assessment methods suffer from subjective and objective inconsistencies. This paper proposes a regional differential information entropy (RDIE) method for image quality assessment to address this problem. This approach allows better assessment of similar but not identical textural details and achieves good agreement with perceived quality. Neural networks are used to reshape the process of calculating information entropy, improving the speed and efficiency of the operation.

CEntRE: A paragraph-level Chinese dataset for Relation Extraction among Enterprises

no code implementations19 Oct 2022 Peipei Liu, Hong Li, Zhiyu Wang, Yimo Ren, Jie Liu, Fei Lyu, Hongsong Zhu, Limin Sun

Enterprise relation extraction aims to detect pairs of enterprise entities and identify the business relations between them from unstructured or semi-structured text data, and it is crucial for several real-world applications such as risk analysis, rating research and supply chain security.

AttentionMixer: An Accurate and Interpretable Framework for Process Monitoring

no code implementations21 Feb 2023 Hao Wang, Zhiyu Wang, Yunlong Niu, Zhaoran Liu, Haozhe Li, Yilin Liao, Yuxin Huang, Xinggao Liu

An accurate and explainable automatic monitoring system is critical for the safety of high efficiency energy conversion plants that operate under extreme working condition.

Visual Tuning

no code implementations10 May 2023 Bruce X. B. Yu, Jianlong Chang, Haixin Wang, Lingbo Liu, Shijie Wang, Zhiyu Wang, Junfan Lin, Lingxi Xie, Haojie Li, Zhouchen Lin, Qi Tian, Chang Wen Chen

With the surprising development of pre-trained visual foundation models, visual tuning jumped out of the standard modus operandi that fine-tunes the whole pre-trained model or just the fully connected layer.
