Clustering by passing messages between data points
 Science
, 2007
"... Clustering data by identifying a subset of representative examples is important for processing sensory signals and detecting patterns in data. Such “exemplars ” can be found by randomly choosing an initial subset of data points and then iteratively refining it, but this works well only if that initi ..."

so in less than onehundredth the amount of time. Clustering data based on a measure of similarity is a critical step in scientific data analysis and in engineering systems. A common approach is to use data to learn a set of centers such that the sum of
Modeling multistep relevance propagation for expert finding
 In CIKM ’08
, 2008
"... An expert finding system allows a user to type a simple text query and retrieve names and contact information of individuals that possess the expertise expressed in the query. This paper proposes a novel approach to expert finding in large enterprises or intranets by modeling candidate experts (pers ..."

Propagation Algorithms for Variational Bayesian Learning
 In Advances in Neural Information Processing Systems 13
, 2001
"... Variational approximations are becoming a widespread tool for Bayesian learning of graphical models. We provide some theoretical results for the variational updates in a very general family of conjugateexponential graphical models. We show how the belief propagation and the junction tree algorithms ..."

algorithms can be used in the inference step of variational Bayesian learning. Applying these results to the Bayesian analysis of linearGaussian statespace models we obtain a learning procedure that exploits the Kalman smoothing propagation, while integrating over all model parameters. We demonstrate how
A hexagon model for 3D Lorentzian quantum cosmology
 PHYS. REV. D
, 2002
"... We formulate a dynamically triangulated model of threedimensional Lorentzian quantum gravity whose spatial sections are flat twotori. It is shown that the combinatorics involved in evaluating the onestep propagator (the transfer matrix) is that of a set of vicious walkers on a twodimensional lat ..."

A Numerical Study of OneStep Models of Polymerization: Frontal versus Bulk Mode”. Elsevier Physica D.
, 2005
"... Abstract In freeradical polymerization, a monomerinitiator mixture is converted into a polymer. Depending on initial and boundary conditions, freeradical polymerization can occur either in a bulk mode (BP) or in a frontal mode (FP) via a propagating selfsustaining reaction front. The main goal o ..."

polymerization mechanism. A mathematical model of onestep freeradical frontal polymerization is identical to the model of gasless combustion, so bulk reactions play a role in the latter context, as well. However, fronts propagate much faster in combustion than in polymerization, and slow bulk reactions
Forward link performance of satellite CDMA with linear interference suppression and onestep power control
 IEEE Trans. Wireless Commun
, 2002
"... (CDMA) is a strong candidate for both terrestrial and satellite components of UMTS. The forwardlink capacity of a satellite DSCDMA system with a conventional matched filter (MF) receiver is limited by interference from adjacent beams and possibly overlapping beams from multiple satellites. In this ..."

The demonstration of onestep growth curves of influenza vires through the blocking effect of irradiated vires on further infection
, 1947
"... Previous studies (1, 2) have shown that the mechanism of infection of susceptible host ceils by influenza virus can be divided into at least four separate phases: (I) the adsorption of the virus onto the host cells (24); (H) the development of changes in the host cells which alter their function (d ..."

ONESTEP GROWTH CURVES OF VARIOUS STRAINS OF IN FLUENZA A AND B VIRUSES AND THEIR INHIBITION BY INACTIVATED VIRUS OF THE HOMOLOGOUS TYPE*
"... Studies on the propagation of influenza viruses in the chick embryo (I) have shown that under certain conditions onestep growth curves may be obtained which are similar in principle to those observed in bacterial hostvirus systems (2, 3). Upon aUantoic injection of either the PR8 strain of influen ..."

Tracking Looselimbed People

Unlike traditional kinematic tree representations, our model of the body is a collection of looselyconnected limbs. Conditional probabilities relating the 3D pose of connected limbs are learned from motioncaptured tr ..."
