This paper extends the connections model of network formation by allowing for players who are heterogeneous with respect to values as well as the costs of forming links. Our principal result is that centrality and short average distances between individuals are robust features of equilibrium networks.  2005 Elsevier Inc. All rights reserved. JEL classification: C72

One of the keywords that describe next-generation wireless communications is “seamless.” As part of the e-Japan Plan promoted by the Japanese Government, the Multimedia Integrated Network by Radio Access Innovation project has as its goal the development of new technologies to enable seamless integration of various wireless access systems for practical use by 2005. This article describes a hete...

In this paper, we investigate the integration of heterogeneous network monitoring data. Specifically, we will synchronize and integrate flow-level records, exemplified by Cisco NetFlow, and packet-level traces, exemplified by NLANR PMA. The integration can facilitate crossvalidation and complementary utility. However, finding the correspondences of timestamps/flows/packets between the PMA and N...

The aim of this paper is to demonstrate, how to communicate the vehicle between themselves in a heterogeneous vehicles network, and show on which way is done the exchange of information with the infrastructure, to overcome the shortcomings of using a single wireless technology. DSRC does not offer enough good coverage and range around intersections in urban areas for specific applications. On t...

Exploding smart phone usage is putting unprecedented pressure on network operators to keep up with this insatiable demand while maintaining quality. The mobile data traffic forecasts, such as Cisco*'s projected 26-fold increase between 2010 and 2015,1 are staggering. Besides consuming massive amounts of network bandwidth, phone subscribers expect the mass availability of new applications and se...

In many economic situations, a player pursues coordination or anti-coordination with her neighbors on a network, but she also has intrinsic preferences among the available options. We here introduce a model which allows to analyze this issue by means of a simple framework in which players endowed with an idiosyncratic identity interact on a social network through strategic complements or substi...

Network embedding has shown its effectiveness in embedding homogeneous networks. Compared with homogeneous networks, heterogeneous information networks (HINs) contain semantic information from multi-typed entities and relations, and are shown to be a more effective model for real world data. The existing network embedding methods fail to explicitly capture the semantics in HINs. In this paper, ...

Multiple treebanks annotated under heterogeneous standards give rise to the research question of best utilizing multiple resources for improving statistical models. Prior research has focused on discrete models, leveraging stacking and multi-view learning to address the problem. In this paper, we empirically investigate heterogeneous annotations using neural network models, building a neural ne...
