The StoyanovskyRibaultTeschner map and string scattering amplitudes,” arXiv:hepth/0505203; G. Giribet, “The String Theory on AdS3 as a Marginal Deformation of a Linear Dilaton Background,” arXiv:hepth/0511252
"... Recently, Ribault and Teschner pointed out the existence of a onetoone correspondence between Npoint correlation functions for the SL(2, C)k/SU(2) WZNW model on the sphere and certain set of 2N − 2point correlation functions in Liouville field theory. This result is based on a seminal work by St ..."

by Stoyanovsky. Here, we discuss the implications of this correspondence focusing on its application to string theory on curved backgrounds. For instance, we analyze how the divergences corresponding to worldsheet instantons in AdS3 can be understood as arising from the insertion of the dual screening operator
Histograms of Oriented Gradients for Human Detection
 In CVPR
, 2005
"... We study the question of feature sets for robust visual object recognition, adopting linear SVM based human detection as a test case. After reviewing existing edge and gradient based descriptors, we show experimentally that grids of Histograms of Oriented Gradient (HOG) descriptors significantly out ..."

Exploration, normalization, and summaries of high density oligonucleotide array probe level data.
 Biostatistics,
, 2003
"... SUMMARY In this paper we report exploratory analyses of highdensity oligonucleotide array data from the Affymetrix GeneChip R system with the objective of improving upon currently used measures of gene expression. Our analyses make use of three data sets: a small experimental study consisting of f ..."

analyses of the probe level data motivate a new summary measure that is a robust multiarray average (RMA) of backgroundadjusted, normalized, and logtransformed P M values. We evaluate the four expression summary measures using the dilution study data, assessing their behavior in terms of bias, variance
Linear dilaton black holes
, 2002
"... We present new solutions to EinsteinMaxwelldilatonaxion (EMDA) gravity in four dimensions describing black holes which asymptote to the linear dilaton background. In the nonrotating case they can be obtained as the limiting geometry of dilaton black holes. The rotating solutions (possibly endowe ..."

Variational algorithms for approximate Bayesian inference
, 2003
"... The Bayesian framework for machine learning allows for the incorporation of prior knowledge in a coherent way, avoids overfitting problems, and provides a principled basis for selecting between alternative models. Unfortunately the computations required are usually intractable. This thesis presents ..."

a unified variational Bayesian (VB) framework which approximates these computations in models with latent variables using a lower bound on the marginal likelihood. Chapter 1 presents background material on Bayesian inference, graphical models, and propagation algorithms. Chapter 2 forms
Linear multiuser detectors for synchronous codedivision multipleaccess channels
 IEEE TRANS. INFORM. THEORY
, 1989
"... In codedivision multipleaccess systems, simultaneous multiuser accessing of a common channel is made possible by assigning a signature waveform to each user. Knowledge of these waveforms enables the receiver to demodulate the data streams of each user, upon observation of the sum of the transmitt ..."

Under the assumptions of symbolsynchronous transmissions and white Gaussian noise, we analyze the detection mechanism at the receiver, comparing different detectors by their bit error rate in the low background noise region, and by their worstcase behavior
Matrix Model and Timelike Linear Dilaton Matter
, 2004
"... We consider a matrix model description of the 2d string theory whose matter part is given by a timelike linear dilaton CFT. This is equivalent to the c = 1 matrix model with a deformed, but very simple fermi surface. Indeed, after a Lorentz transformation, the corresponding 2d spacetime is a conven ..."

We show that the tree level scattering amplitudes in the matrix model perfectly agree with those computed in the worldsheet theory. The classical trajectories of fermions correspond to the decaying Dbranes in the timelike linear

The full string theory in such vacua is “dual ” to a theory without gravity in fewer dimensions. The dual theory is generically not a local quantum field theory. Excitations of the st ..."
