Simplicial ising dynamics
For a 2-simplicial complex structure with N nodes, when predicting the 2-simplexes of a node i, we randomly choose two nodes (e.g., j and k) and calculate the probability Pjk→i, which requires calculating \(\left(\genfrac{}{}{0.0pt}{}{N-1}{2}\right)\) values. To reduce the computational load and increase the reconstruction … Visa mer Let j → i denote the event that node j has a direct impact on the state of node i. For example, node j can directly spread the virus or send a piece of information to … Visa mer We next use the EM method to maximize the likelihood function57 for determining the parameter Θ in Eq. 6. Taking the logarithm form of Eq. 6, we get Applying … Visa mer Webb6 nov. 2024 · Dynamics of the system Disordered Ising systems In statistical mechanics, the Ising model is a simplified representation of the interaction between individual magnetic moments in a ferromagnetic substance, for example, a refrigerator magnet.
