A model of RD-IHSAT rumor dissemination based on coupling network by Yishi HAN, Yuxin XU, Tiantian LU

“…To explore the spread of rumors in social network, based on the principles of coupling network, the model of RD-IHSAT was established on Barabási-Albert (BA) scale free network and Watts-Strogatz (WS) small world network.The classic model of SIR was optimized, by combining it with three concerns, the interest decay, the social consensus and the spiral of silence effect, and adding four roles, hesitated, adherent, reticent and debunker.Results of numerical simulations are as follows: an information outbreak can be triggered by coupling network, not only the spreading speed but the scale as well; the dissemination can be markedly suppressed when the probability of rumor-refuting for the hesitated and spreaders arises; the chances of transition from spreaders to adherents drop; increasing the proportion of silent groups is a key part of curbing the spread of rumors; the control of the time lag in refuting rumors will greatly affect the effect of refuting rumors.…”

Runoff Forecasting Research Coupling Quadratic Factor Screening and Deep Learning by CHENG Liwen, HUANG Shengzhi, LI Pei, LI Ziyan, JIA Songtao, HUANG Qiang

“…The effective screening of factors influencing runoff is a key aspect of runoff forecasting research.However,there are many factors affecting runoff,and these factors have complex interactions.Most of the existing studies use numerically driven models with primary factor screening,and the results show that the input factors are spatially redundant,leading to poor forecasting results.In view of this,the support vector regression (SVR) and the long-short memory network model (LSTM) are compared with Weihe River Basin as an example,and the LSTM model is selected as the optimal forecasting model.Principal component analysis and gray correlation analysis are used for secondary screening of the input terms to form a model coupling principal component analysis,gray correlation analysis,and LSTM.The results show that:①the fitting accuracy of LSTM is higher than that of SVR;②the secondary screening of the input terms improves the forecast accuracy,and the forecast accuracy of the coupled model is better than that of the single model,specifically,the model accuracy evaluation indexes of the coupled model are substantially improved compared with those of the single model;③the Nash efficiency coefficient and deterministic coefficient of the coupled model of gray system correlation analysis are improved by 0.13% and 0.03%,respectively,compared with those of the coupled model of principal component analysis,and the standard deviation ratio of observed values is improved by 42.9%.The study shows that the secondary factor screening by using gray correlation can effectively improve forecast accuracy.…”

An Iterative Algorithm for the Generalized Reflexive Solutions of the Generalized Coupled Sylvester Matrix Equations by Feng Yin, Guang-Xin Huang

“…When the matrix equations are consistent, for any initial generalized reflexive matrix pair [X1,Y1], the generalized reflexive solutions can be obtained by the iterative algorithm within finite iterative steps in the absence of round-off errors, and the least Frobenius norm generalized reflexive solutions can be obtained by choosing a special kind of initial matrix pair. The unique optimal approximation generalized reflexive solution pair [X̂,Ŷ] to a given matrix pair [X0,Y0] in Frobenius norm can be derived by finding the least-norm generalized reflexive solution pair [X̃*,Ỹ*] of a new corresponding generalized coupled Sylvester matrix equation pair (AX̃B-CỸD,EX̃F-GỸH)=(M̃,Ñ), where M̃=M-AX0B+CY0D,Ñ=N-EX0F+GY0H. …”
