2015/11/12
The United Nations Statistical Commission celebrates the fifth annual World Statistics Day today. Over 60 countries have joined together to coordinate activities based on the theme of "Bette...
Where the Cathedrals and Bazaars Are: An Index of Open Source Software Activity and Potential
Index construction open source software technology diffusion technology policy
2014/11/26
This article presents a framework to measure activity and potential for open source software development and use at a country level. The framework draws on interviews with experts in the open source s...
Automatic Estimation of Flux Distributions of Astrophysical Source Populations
Broken power law CDFN X-ray survey Interwoven EM algorithm Likelihood com-putations logN logS Pareto distribution
2013/6/13
In astrophysics a common goal is to infer the flux distribution of populations of scientifically interesting objects such as pulsars or supernovae. In practice, inference for the flux distribution is ...
Understanding the source of multifractality in financial markets
Understanding source multifractality financial markets
2012/3/2
In this paper, we use the generalized Hurst exponent approach to study the multi- scaling behavior of different financial time series. We show that this approach is robust and powerful in detecting di...
Impact of Internal Open Source Development on Reuse: Participatory Reuse in Action
closed source internal open source open source open source software participatory reuse
2011/10/6
Adoption of open source software (OSS) principles to internal software development has gained considerable momentum. Often labeled as "internal open source" (IOS), several large firms have started to ...
Source Separation and Clustering of Phase-Locked Subspaces: Derivations and Proofs
Index Terms—phase-locking synchrony source separation
2011/7/5
Due to space limitations, our submission "Source Separation and Clustering of Phase-Locked Subspaces", accepted for publication on the IEEE Transactions on Neural Networks in 2011, presented some resu...
Closed-Form EM for Sparse Coding and Its Application to Source Separation
Closed-Form EM Sparse Coding Source Separation
2011/6/17
We define and discuss the first sparse coding algorithm based on closed-form EM
updates and continuous latent variables. The underlying generativemodel consists
of a flexibly parameterized ‘spike-an...
Sparse Signal Recovery with Temporally Correlated Source Vectors Using Sparse Bayesian Learning
Bayesian Learning Temporally Correlated Signal Recovery
2011/3/23
We address the sparse signal recovery problem in the context of multiple measurement vectors (MMV) when elements in each nonzero row of the solution matrix are temporally correlated. Existing algorith...

Quality of Source Location Protection in Globally Attacked Sensor Networks
Cryptography and Security (cs.CR) Probability (math.PR) Statistics Theory (math.ST)
2010/12/17
We propose an efficient scheme for generating fake network traffic to disguise the real event notification in the presence of a global eavesdropper, which is especially relevant for the quality of ser...
Downscaling extremes: A comparison of extreme value distributions in point-source and gridded precipitation data
Primary projections of extreme events reanalysis
2010/10/19
There is substantial empirical and climatological evidence that precipitation extremes have become more extreme during the twentieth century, and that this trend is likely to continue as global warmi...
