Supervised Random Walks: Predicting and Recommending Links in Social Networks
"... Predicting the occurrence of links is a fundamental problem in networks. In the link prediction problem we are given a snapshot of a network and would like to infer which interactions among existing members are likely to occur in the near future or which existing interactions are we missing. Althoug ..."

Distributed Connectivity Control of Mobile Networks
, 2007
"... Control of mobile networks raises fundamental and novel problems in controlling the structure of the resulting dynamic graphs. In particular, in applications involving mobile sensor networks and multi-agent systems, a great new challenge is the development of distributed motion algorithms that guara ..."

that guarantee connectivity of the overall network. In this paper, we address this challenge using a novel control decomposition. First, motion control is performed in the continuous state space, where nearest neighbor potential fields are used to maintain existing links in the network. Second, distributed
Computing person and firm effects using linked longitudinal employer-employee data,” Center for Economic Studies, US Census Bureau,
, 2002
"... Abstract In this paper we provide the exact formulas for the direct least squares estimation of statistical models that include both person and firm effects. We also provide an algorithm for determining the estimable functions of the person and firm effects (the identifiable effects). The computati ..."

From a statistical perspective, connected groups of workers and firms block-diagonalize the normal equations (see equation
A Prediction-based Link Availability Estimation for Mobile Ad Hoc Networks
, 2001
"... One critical issue for routing in mobile ad hoc networks (MANET) is how to select a reliable path that can last longer since mobility may cause radio links to break frequently. To answer this question, a criterion that can judge path reliability is needed. The reliability of a path depends on the av ..."

Nonparametric Link Prediction in Dynamic Networks
"... Facebook (This work was partly done when the author was at Yahoo! Research) We propose a nonparametric link prediction algorithm for a sequence of graph snapshots over time. The model predicts links based on the features of its endpoints, as well as those of the local neighborhood around the endpoin ..."

Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Furthermore, these co-operations are based increasingly on sharing of information. These are information networks, which, in the limit, link up suppliers
1Link Estimation and Routing in Sensor Network Backbones: Beacon-based or Data-driven?
"... Abstract — In the context of IEEE 802.11b network testbeds, we examine the differences between unicast and broadcast link properties, and we show the inherent difficulties in precisely estimating unicast link properties via those of broadcast beacons even if we make the length and transmission rate ..."

based on ETX/ETT-type metrics, but the metrics are estimated via MAC feedback for unicast data transmission instead of broadcast beacons. Using a realistic sensor network traffic trace and an 802.11b testbed of ∼195 Stargates, we experimentally compare the performance of LOF with that of beacon
Signal Processing Techniques in Network-Aided Positioning: A Survey of State-ofthe-Art Positioning Designs
- IEEE Signal Processing Magazine
, 2005
"... [A survey of state-of-the-art positioning designs] The U.S. Federal Communications Commission (FCC) requires that the precise location of all enhanced 911 (E911) callers be automatically determined. This requirement has motivated the development of cellular-aided positioning. To facilitate emergency ..."

Positioning systems can be grouped in many different ways
1Range-based Mobility Estimations in MANETs with Application to Link Availability Prediction
"... Abstract — The quality of communications in mobile ad-hoc networks is largely determined by the topological stability. Characterizing the mobility of mobile nodes (e.g. how often they move away from each other) would enable the measurement of the frequency of network reconfigurations for predicting ..."

stability. In this paper, we first define a triplet 〈V,Θ,Ψ 〉 which consists of mobility parameters that are directly correlated with the stability of a network (e.g. inter-node relative speeds/orientations and epoch time). Based on our previous study on range-based velocity estimations, we then propose a
