A new modelindependent way of extracting Vub/Vcb
, 2002
"... The ratio between the photon spectrum in B → Xsγ and the differential semileptonic rate wrt the hadronic variable MX/EX is a shortdistance quantity calculable in perturbation theory and independent of the Fermi motion of the b quark in the B meson. We present a NLO analysis of this ratio and show h ..."

how it can be used to determine Vub/Vcb  independently of any model for the shape function. We also discuss how this relation can be used to test the validity of the shapefunction theory on the data. 1
Modelindependent WIMP Searches at the ILC
, 709
"... We investigate the possibility to detect WIMPs at the ILC in a modelindependent way using events with single photons. The study is done with a full detector simulation of the LDC detector and MarlinReco. It turns out that WIMPs are observable this way at the ILC if their coupling to electrons is no ..."

Quarkonium Formation Time in a ModelIndependent Approach
, 1999
"... We use dispersion relations to reconstruct, in a model–independent way, the formation dynamics of heavy quarkonium from the experimental data on e + e − → ¯ QQ annihilation. We extract a distribution of formation times with a mean value for the J/ψ, < τ J/ψ> = 0.44 fm; and for the Υ, < τΥ ..."

Training Products of Experts by Minimizing Contrastive Divergence
, 2002
"... It is possible to combine multiple latentvariable models of the same data by multiplying their probability distributions together and then renormalizing. This way of combining individual “expert ” models makes it hard to generate samples from the combined model but easy to infer the values of the l ..."

Diagnosing multiple faults.
 Artificial Intelligence,
, 1987
"... Abstract Diagnostic tasks require determining the differences between a model of an artifact and the artifact itself. The differences between the manifested behavior of the artifact and the predicted behavior of the model guide the search for the differences between the artifact and its model. The ..."

with sequential diagnosis to propose measurements to localize the faults. The normally required conditional probabilities are computed from the structure of the device and models of its components. This capability results from a novel way of incorporating probabilities and information theory into the context
WIMP Searches at the ILC using a modelindependent Approach
, 901
"... In this note the ILC’s capabilities for detecting WIMPs and measuring their properties are studied. The expected signal cross section is derived in a modelindependent way from the observed relic density of Dark Matter. Signal events are detected by means of initial state radiation (ISR). The study ..."

Modelindependent information on γ from B ± → πK Decays
, 1999
"... Measurements of the rates for the hadronic decays B ± → πK can be used to derive information on the weak phase γ = arg(V ∗ ub) in a largely modelindependent way. Hadronic uncertainties can be reduced to the level of nonfactorizable contributions to the decay amplitudes that are powersuppressed in ..."

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 errorcorrecting codes. The most dramatic instance of this is the near Shannonlimit performanc ..."

simulations we did not set the observed nodes by sampling from the joint for low priors all the findings would be negative and inference would be trivial. Rather each finding was independently set to positive or negative. If indeed small priors are responsible for the oscilla tion, then we would expect
