HACKING SPATIAL DATA: AN EXAMPLE OF AGGREGATION PROBLEMS
Spatial aggregation Spatial data science Hacking spatial data Spatial autocorrelation
2018/11/8
Many applications using spatially aggregated data tend to treat the spatial units as given. For example, in the United States, analyses using the social and economic data often rely on the existing an...
A Survey of Two Signature Aggregation Techniques
Signature Aggregation Techniques signature scheme
2015/8/5
We survey two recent signature constructions that support signature aggregation: Given n signatures on n distinct messages from n distinct users, it is possible to aggregate all these signatures into ...
NETWORK STRUCTURE AND THE AGGREGATION OF INFORMATION: THEORY AND EVIDENCE FROM INDONESIA
Networks Diff usion of information Targeting Development
2015/7/15
We use unique data from 600 Indonesian communities on what individuals know about
the poverty status of others to study how network structure influences information aggregation.
We develop a m...

COBRA: A Nonlinear Aggregation Strategy
Regression estimation aggregation nonlinearity consistency prediction
2013/4/27
A new method for combining several initial estimators of the regression function is introduced. Instead of building a linear or convex optimized combination over a collection of basic estimators $r_1,...
Aggregation of autoregressive random fields and anisotropic long memory
Aggregation autoregressive random fields anisotropic long memory
2013/4/27
We introduce the notion of anisotropic long memory for random fields on $\mathbb{Z}^2$ whose partial sums on incommensurate rectangles with sides growing at different rates O(n) and $O(n^{H_1/H_2})$, ...
Majority Dynamics and Aggregation of Information in Social Networks
Majority Dynamics Aggregation of Information Social Networks
2012/9/18
Considernindividuals who, by popular vote, choose among q≥2 alternatives, one of which is “better” than the others. Assume that each individual votes independently at random, and that the probability ...
Effects of polymer concentration and chain length on aggregation in physically associating polymer solutions
concentration chain length aggregation associative polymer
2012/2/24
The effects of polymer concentration and chain length on aggregation in associative polymer solutions, are studied using self-consistent field lattice model. Only two inhomogenous morphologies, i.e. m...

This note constitutes a corrigendum to the article of Azomahou, JSPI, 139:2581-2597.
Variational Bayes approach for model aggregation in unsupervised classification with Markovian dependency
Model averaging Variational Bayes inference Markov Chain Unsu-pervised classification
2011/6/16
We consider a binary unsupervised classi cation problem where each observation
is associated with an unobserved label that we want to retrieve. More precisely, we
assume that there are two groups of...
Information Aggregation of Group Decision-Making in Emergency Events
Emergency Group Decision-Making Information Aggregation Relative Entropy
2013/1/29
Information is a key factor in emergency management, which helps decision makers to make effective decisions. In this paper, aiming at clarifying the information aggregation laws, and according to the...
A Privacy Preserving Attribute Aggregation Model for Federated Identity Managements
A Privacy Preserving Attribute Aggregation Model Federated Identity Managements
2010/9/25
In order to support attribute based access control (ABAC) infederated identity management most existing solutions, such asShibboleth and Cardspace, utilise a model in which a single identityprovider (...
Sparse Regression Learning by Aggregation and Langevin Monte-Carlo
learning regression estimation logistic regression oracle inequalities sparsity prior Langevin Monte-Carlo
2010/3/18
We consider the problem of regression learning for deterministic design and independent random errors.We start by proving a sharp PAC-Bayesian type bound for the exponentially weighted aggregate (EWA)...
Optimal rates and adaptation in the single-index model using aggregation
Nonparametric regression single-index aggregation adaptation minimax random design oracle inequality
2009/9/16
We want to recover the regression function in the single-index model. Using an aggregation algorithm with local polynomial estimators, we answer in particular to the second part of Question 2 from Sto...
Aggregation in Swarm Robotic Systems: Evolution and Probabilistic Control

2009/7/28
In this study we investigate two approachees for aggregation behavior in swarm robotics systems: Evolutionary methods and probabilistic control. In first part, aggregation behavior is chosen as a case...
