, 2007
"... Random geometric graphs have been one of the fundamental models for reasoning about wireless networks: one places n points at random in a region of the plane (typically a square or circle), and then connects pairs of points by an edge if they are within a fixed distance of one another. In addition t ..."

only take place among nodes when they are close in space and when they have lineofsight access to one another — consider, for example, urban settings or large indoor environments. In such domains, the standard model of random geometric graphs is not a good approximation of the true constraints, since
Connectivity for lineofsight networks in higher dimensions
"... Let T be a ddimensional toroidal grid of n d points. For a given range parameter ω, and a positive integer k ≤ d, we say that two points in T are mutually visible if they differ in at most k coordinates and are a distance at most ω apart, where distance is measured using the ℓp norm. We obtain a ra ..."

random ddimensional lineofsight graph G by placing a node at each point in T independently with some fixed probability p ∗ and connecting all pairs of mutually visible nodes. We prove an asymptotically tight connectivity result for this random graph.

Lineofsight percolation
, 2008
"... Given ω ≥ 1, let Z 2 (ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z 2 (1) is precisely Z 2.) Let pc(ω) be the critical probability for site percolation on Z 2 (ω). Extending recent results of Frieze, ..."

Given ω ≥ 1, let Z 2 (ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z 2 (1) is precisely Z 2.) Let pc(ω) be the critical probability for site percolation on Z 2 (ω). Extending recent results of Frieze, Kleinberg, Ravi and Debany, we show that limω→ ∞ ωpc(ω) = log(3/2). We also prove analogues of this result for the nbyn grid and in higher dimensions, the latter involving interesting connections to Gilbert’s continuum percolation model. To prove our results, we explore the component of the origin in a certain nonstandard way, and show that this exploration is well approximated by a certain branching random walk.

"... Abstract: This paper proposes threedimensional fuzzy missile guidance laws based on lineofsight, proportional navigation, and mixed strategy guidance. The results are promising and clearly demonstrate the potential of fuzzy guidance schemes against nonmaneuvering and maneuvering targets. The mi ..."

Mining the Network Value of Customers
 In Proceedings of the Seventh International Conference on Knowledge Discovery and Data Mining
, 2002
"... One of the major applications of data mining is in helping companies determine which potential customers to market to. If the expected pro t from a customer is greater than the cost of marketing to her, the marketing action for that customer is executed. So far, work in this area has considered only ..."

only the intrinsic value of the customer (i.e, the expected pro t from sales to her). We propose to model also the customer's network value: the expected pro t from sales to other customers she may inuence to buy, the customers those may inuence, and so on recursively. Instead of viewing a market
Bayesian Network Classifiers

Recent work in supervised learning has shown that a surprisingly simple Bayesian classifier with strong assumptions of independence among features, called naive Bayes, is competitive with stateoftheart classifiers such as C4.5. This fact raises the question of whether a classifier with less restr ..."
