Entropy production in the majority-vote model.

چکیده
We analyzed the entropy production in the majority-vote model by using a mean-field approximation and Monte Carlo simulations. The dynamical rules of the model do not obey detailed balance so that entropy is continuously being produced. This nonequilibrium stochastic model is known to have a critical behavior belonging to the universality class of the equilibrium Ising model. We show that the entropy production exhibits a singularity at the critical point whose exponent is estimated numerically.

This paper investigates the effect of redistributive politics on the composition of government expenditure. By applying a dynamic and complete information game, it is shown that the quality of institutions is a key determinant of how much the government revenue is spent on public goods. The main finding of this paper is that in democracies with high quality of institution, less transfer is dem...
متن کامل(Measuring System Entropy Generation in a Complex Economic Network (The Case of Iran
An economic system is comprised of different primary flows that can be captured in macroeconomic models with complex network relations. Theoretically and empirically in this system, weak substitution or complementarity of environmental materials, like energy and other production factors such as capital, is undeniable. This is an effective critique on neoclassical economics. In this paper, we vi...
متن کاملLearning with Randomized Majority Votes
We propose algorithms for producing weighted majority votes that learn by probing the empirical risk of a randomized (uniformly weighted) majority vote—instead of probing the zero-one loss, at some margin level, of the deterministic weighted majority vote as it is often proposed. The learning algorithms minimize a risk bound which is convex in the weights. Our numerical results indicate that le...
متن کاملPhase Transitions in Equilibrium and Non-Equilibrium Models on Some Topologies
On some regular and non-regular topologies, we studied the critical properties of models that present up-down symmetry, like the equilibrium Ising model and the nonequilibrium majority vote model. These are investigated on networks, like Apollonian (AN), Barabási–Albert (BA), small-worlds (SW), Voronoi–Delaunay (VD) and Erdös–Rényi (ER) random graphs. The review here is on phase transitions, cr...
متن کاملOn Using Ensemble Methods for Chinese Named Entity Recognition
In sequence labeling tasks, applying different machine learning models and feature sets usually leads to different results. In this paper, we exploit two ensemble methods in order to integrate multiple results generated under different conditions. One method is based on majority vote, while the other is a memory-based approach that integrates maximum entropy and conditional random field classif...
