Intelligent Medical Diagnosis Model Based on Graph Neural Networks for Medical Images
CAAI Transactions on Intelligence Technology, Volume 10, Issue 4, Page 1201-1216, August 2025.ABSTRACT Recently, numerous estimation issues have been solved due to the developments in data‐driven artificial neural networks (ANN) and graph neural networks (GNN). The primary limitation of previous methodologies has been the dependence on data that can be structured in a grid format.

Network Analysis of the Organic Chemistry in Patents, Literature, and Pharmaceutical Industry
Molecular Informatics, Volume 44, Issue 7, July 2025.Knowledge graphs built on AstraZeneca electronic lab notebook, US Patent and Trademark Office (USPTO) and Reaxys chemical reaction data are compared using various knowledge graph metrics. Chemical reactions can be connected in large networks such as knowledge graphs.

Tournaments, 4-uniform hypergraphs, and an exact extremal result
, 2016 We consider $4$-uniform hypergraphs with the maximum number of hyperedges subject to the condition that every set of $5$ vertices spans either $0$ or exactly $2$ hyperedges and give a construction, using quadratic residues, for an infinite family of such

Generalized Kneser coloring theorems with combinatorial proofs
, 2001 The Kneser conjecture (1955) was proved by Lov\'asz (1978) using the Borsuk-Ulam theorem; all subsequent proofs, extensions and generalizations also relied on Algebraic Topology results, namely the Borsuk-Ulam theorem and its extensions.

Learning Hypergraph-regularized Attribute Predictors
, 2015 We present a novel attribute learning framework named Hypergraph-based Attribute Predictor (HAP). In HAP, a hypergraph is leveraged to depict the attribute relations in the data. Then the attribute prediction problem is casted as a regularized hypergraph

Polymatroids and polyquantoids [PDF]
, 2012 When studying entropy functions of multivariate probability distributions, polymatroids and matroids emerge. Entropy functions of pure multiparty quantum states give rise to analogous notions, called here polyquantoids and quantoids.

A Combinatorial Approach to Nonlocality and Contextuality
, 2015 So far, most of the literature on (quantum) contextuality and the Kochen-Specker theorem seems either to concern particular examples of contextuality, or be considered as quantum logic.

Probabilistic existence of regular combinatorial structures
, 2017 We show the existence of regular combinatorial objects which previously were not known to exist. Specifically, for a wide range of the underlying parameters, we show the existence of non-trivial orthogonal arrays, t-designs, and t-wise permutations.

Application of Hypergraph-Driven "Trinity" Semantic Framework in Retail Commodity Detection
物联网学报The efficiency of retail checkout systems directly affects the shopping experience. Current systems have difficulty capturing key details of Small-sized merchandise and lack spatial reasoning in crowded scenes, which limits detection performance.
