Rich Neighbors
Theories of economic development suggest variously that national income increases or decreases the propensity for states to fight, while systematic evidence of the impact of development on warfare is ambiguous or non-existent. The lack of empirical support for nominally opposing claims can be reconciled if elements of both sets of arguments are partially correct. We use a formal model to constr...
متن کاملNearest-neighbors medians clustering
We propose a nonparametric cluster algorithm based on local medians. Each observation is substituted by its local median and this new observation moves toward the peaks and away from the valleys of the distribution. The process is repeated until each observation converges to a fixpoint. We obtain a partition of the sample based on the convergence points. Our algorithm determines the number of c...
متن کاملShare with Thy Neighbors
Peer to peer (P2P) systems are traditionally designed to scale to a large number of nodes. However, we focus on scenarios where the sharing is effected only among neighbors. Localized sharing is particularly attractive in scenarios where wide area network connectivity is undesirable, expensive or unavailable. On the other hand, local neighbors may not offer the wide variety of objects possible ...
متن کاملVoronoi Natural Neighbors Interpolation
Implementing point cloud to grid conversion for digital elevation maps (DEM) presents one with many options for interpolation and we intend to explore algorithms for interpolation during the conversion process with a specific focus on Voronoi natural neighbor interpolation. By partitioning the environment into Voronoi cells and using the information from neighboring cells and their respective g...
