Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

to the correct marginals. However, on the QMR network, the loopy be liefs oscillated and had no obvious relation ship to the correct posteriors. We present some initial investigations into the cause of these oscillations, and show that some sim ple methods of preventing them lead to the wrong results
A Note on Certain Stability and Limiting Properties of ν-infinitely divisible distributions
"... Abstract. The class of ν-infinitely divisible (ID) distributions, which arise in connection with random summation, is a reach family including geometric infinitely divisible (GID) and geometric stable (GS) laws. We present two sim-ple results connected with triangular arrays with random number of te ..."

Expectation-propagation for the generative aspect model
- in UAI-2000, Proceedings of the 18th Conference in Uncertainty in Artificial Intelligence
"... The generative aspect model is an extension of the multinomial model for text that allows word probabilities to vary stochastically across docu-ments. Previous results with aspect models have been promising, but hindered by the computa-tional difficulty of carrying out inference and learning. This p ..."

. This paper demonstrates that the sim-ple variational methods of Blei et al. (2001) can lead to inaccurate inferences and biased learning for the generative aspect model. We develop an alternative approach that leads to higher accuracy at comparable cost. An extension of Expectation-Propagation is used
Boundary Recognition in Sensor Networks by Topological Me ods
- in Proc. of MOBICOM
, 2006
"... Wireless sensor networks are tightly associated with the un-derlying environment in which the sensors are deployed. The global topology of the network is of great importance to both sensor network applications and the implementation of net-working functionalities. In this paper we study the problem ..."

We propose a sim-ple, distributed algorithm that correctly detects nodes on the boundaries and connects them into meaningful bound-ary cycles. We obtain as a

Homophily and contagion are generically confounded in observational social network studies
- Sociological Methods & Research
"... We consider processes on social networks that can potentially involve three factors: homophily, or the formation of social ties due to matching individual traits; social contagion, also known as social influence; and the causal effect of an individual’s covariates on their behavior or other mea-sura ..."

-surable responses. We show that, generically, all of these are confounded with each other. Distinguishing them from one another requires strong as-sumptions on the parametrization of the social process or on the adequacy of the covariates used (or both). In particular we demonstrate, with sim-ple examples
Flumejava: Easy, efficient data-parallel pipelines
- PLDI ’10, ACM
"... MapReduce and similar systems significantly ease the task of writ-ing data-parallel code. However, many real-world computations re-quire a pipeline of MapReduces, and programming and managing such pipelines can be difficult. We present FlumeJava, a Java li-brary that makes it easy to develop, test, ..."

"... The ability to create templated nanostruc-tures of arbitrarily high aspect ratio at low tem-peratures and with outstanding geometric con-trol distinguishes ALD (atomic layer deposi-tion) from most other gas-solid thin film de-position techniques [1]. The integration of ALD with other nanostructuring ..."
Abstract

nanostructuring procedures requires the availability of reliable and sim-ple ALD protocols for some standard materials with favorable chemical, mechanical, and elec-trical properties. Among these, SiO2 has long represented a challenge in the ALD commu-nity. This unfortunate situation can be traced back
New analytic results for speciation times in neutral models
, 2008
"... In this paper we investigate the standard Yule model, and a recently stud-ied model of speciation and extinction, the ‘critical branching process’. We develop an analytic way – as opposed to the common simulation approach– for calculating the speciation times in a reconstructed phylogenetic tree. Si ..."
