Hypergraph model
WebIn this study, PHAT is proposed, a deep hypergraph learning framework for the prediction of peptide secondary structures and the exploration of downstream tasks. The framework includes a novel interpretable deep hypergraph multi-head attention network that uses residue-based reasoning for structure prediction. Web3 jan. 2024 · Meanwhile, two comprehensive evaluation metrics, i.e., a complex contagion model in hypergraphs, which mimics the group influence during the spreading process and network s -efficiency based on the higher-order distance between nodes, are first proposed to evaluate the effectiveness of our methods.

WebTherefore, we propose a multi-channel hypergraph topic convolution neural network ( C 3 -HGTNN). By exploring complete and latent high-order correlations, we integrate topic and graph model to build trace and activity representations in the topics space (among activity-activity, trace-activity and trace-trace). Web11 aug. 2024 · Mean Field Analysis of Hypergraph Contagion Model. Desmond J. Higham, Henry-Louis de Kergorlay. We typically interact in groups, not just in pairs. For this …
WebHere, we develop a nonlinear diffusion process on hypergraphs that spreads both features and labels following the hypergraph structure. Even though the process is nonlinear, we show global convergence to a unique limiting point for a broad class of nonlinearities and we show that such limit is the global minimum of a new regularized semi ... Web1 okt. 2006 · This paper fills the gap by presenting the hypergraph‐based systems model as being more versatile than are the models known from literature, and highlights the effect of system elements and relations on the make‐up of the system in point. Purpose – To present the hypergraph as a systems model that is more versatile than are the …
WebWe do so by comparing the hypergraph stochastic block model with its Erd{\"o}s-R{\'e}nyi counterpart. We also obtain estimates for the parameters of the hypergraph stochastic block model. The methods developed in this paper are generalised from the study of sparse random graphs by Mossel et al. 2015 and are motivated by the work of Yuan et al. 2024. WebHence, a Bayesian hypergraph model allows much finer factorizations and thus achieves higher mem-ory e ciency. Remark 3. We remark that the factorization for-mula defined in (3) is in fact the most general pos-sible in the sense that it allows all possible factor-izations of a probability distribution admitted by a DAH.
