Towards a classification of networks with asymmetric inputs

چکیده

Coupled cell systems associated with a coupled network are determined by (smooth) vector fields that consistent the structure. Here, we follow formalisms of Stewart, Golubitsky and Pivato (Symmetry groupoids patterns synchrony in networks, SIAM J. Appl. Dyn. Syst. 2 (4) (2003) 609--646), Golubistky, Stewart Torok (Patterns networks multiple arrows, Dynam. Sys. 4 (1) (2005) 78--100) Field (Combinatorial dynamics, Dynamical Systems 19 (2004) (3) 217--243). It is known two non-isomorphic n-cell can determine same sets -- these said to be ODE-equivalent. The set all so partitioned into classes ODE-equivalent networks. With no further restrictions, number ODE-classes not finite each class has an infinite Inside ODE-class find subclass minimize edges class, called minimal In this paper, consider asymmetric inputs. That is, if k distinct types, have property every receives inputs, one type. Fixing n cells, prove that: finite; restricting maximum n(n-1) cover ODE-classes; inputs We also give simple criterion test conjecture lower estimates for any Moreover, present full list representatives three cells

Strategyproof Classification with Shared Inputs

Strategyproof classification deals with a setting where a decision-maker must classify a set of input points with binary labels, while minimizing the expected error. The labels of the input points are reported by self-interested agents, who might lie in order to obtain a classifier that more closely matches their own labels, thus creating a bias in the data; this motivates the design of truthfu...

Training Random Asymmetric`neural' Networks towards Chaos { a Progress Report

We explore a non-Hebbian plasticity algorithm for a random asymmetric 'neural' network in synchronous, discrete time, which causes the period of the network's inherent limit cycles to quickly diverge with the plasticity parameter. The limit cycle period has a strong peak as we increase the neural units' thresholds from normal thresholds. It is much easier to increase the limit cycle period by t...

A Developed Asymmetric Multilevel Inverter with Lower Number of Components

In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic dev...

A COMPREHENSIVE APPROACH TOWARDS THE CLASSIFICATION OF CRACKS IN UN-REINFORCED MASONRY BUILDINGS

Cracks emerge due to various forces or stresses. After discerning the cracks preferably by non-destructive techniques, there is a need to find the reason for their appearance. With very exact analysis of the shape, form and dimension of the cracks and their location on the structural elements, we can deduce the reason for their formation.  This makes, proposing a suitable solution for preventin...
