Specialization Models of Network Growth

Specialization Models of Network Growth

One of the most important features observed in real networks is that, as a network’s topology evolves so does the network’s ability to perform various complex tasks. To explain this, it has also been observed that as a network grows certain subnetworks begin to specialize the function(s) they perform. Here, we introduce a class of models of network growth based on this notion of specialization ...

Evaluating and Optimising Models of Network Growth

This paper presents a statistically sound method for measuring the accuracy with which a probabilistic model reflects the growth of a network, and a method for optimising parameters in such a model. The technique is data-driven, and can be used for the modeling and simulation of any kind of evolving network. The overall framework, a Framework for Evolving Topology Analysis (FETA), is tested on ...

Labor Specialization and Endogenous Growth

Defining Specialization for Process Models

Object-oriented analysis and design methods take full advantage of the object specialization hierarchy when it comes to modeling the objects in a system. When modeling system behavior, however, system analysts continue to rely on traditional tools such as state diagrams and dataflow diagrams. While such diagrams capture important aspects of the processes they model, they offer limited guidance ...

Uncertainty, Optimal Specialization and Growth

We present a novel argument demonstrating that when trade is characterized by uncertainty the comparative advantages doctrine is misleading and a positive level of diversification is growth enhancing. Applying a result developed in the mathematical biological literature, we show that, in Ricardian trade model in which capital available for investment depends on previous periods returns, incompl...
