Linear response formula for open systems.
An exact expression for the finite frequency response of open classical systems coupled to reservoirs is obtained. The result is valid for any conserved current. No assumption is made about the reservoirs apart from thermodynamic equilibrium. At nonzero frequencies, the expression involves correlation functions of boundary currents and cannot be put in the standard Green-Kubo form involving cur...
متن کاملA New Method for Improving Computational Cost of Open Information Extraction Systems Using Log-Linear Model
Information extraction (IE) is a process of automatically providing a structured representation from an unstructured or semi-structured text. It is a long-standing challenge in natural language processing (NLP) which has been intensified by the increased volume of information and heterogeneity, and non-structured form of it. One of the core information extraction tasks is relation extraction wh...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولLinear Response Formula and Generalized Belief Propagation for Probabilistic Inference
In probabilistic inference for signal processing, medical diagnosis, code theory, digital communication, machine learning and so on, belief propagation (BP) is one of powerful approximate methods to calculate a belief for each node within a practical computational time[1]. Recently, it has been pointed out that the BP has some mathematical structures in common with advanced mean-field (MF) meth...
متن کاملLinear Response Formula for Piecewise Expanding Unimodal Maps
The average R(t) = R φdμt of a smooth function φ with respect to the SRB measure μt of a smooth one-parameter family ft of piecewise expanding interval maps is not always Lipschitz [4], [17]. We prove that if ft is tangent to the topological class of f , and if ∂tft|t=0 = X ◦ f , then R(t) is differentiable at zero, and R(0) coincides with the resummation proposed in [4] of the (a priori diverg...
