Optimal and fast detection of spatial clusters with scan statistics
Scan statistic Bernoulli model optimal detection multiscaleinference fast algorithm concentration inequality
2010/3/10
We consider the detection of multivariate spatial clusters in the
Bernoulli model with N locations, where the design distribution has
weakly dependent marginals. The locations are scanned with a rec...
Optimal properties of centroid-based classifiers for very high-dimensional data
Centroid method classification discrimination distance-basedclassifiers high-dimensional data location differences minimax performance
2010/3/11
We show that scale-adjusted versions of the centroid-based classi-
fier enjoys optimal properties when used to discriminate between two
very high-dimensional populations where the principal differen...
Robust Independent Component Analysis by Iterative Maximization of the Kurtosis Contrast with Algebraic Optimal Step Size
Atrial fibrillation (AF) blind source separation (BSS) independent component analysis (ICA) iterative optimization kurtosis
2010/3/10
Independent component analysis (ICA) aims at decomposing an observed random vector into
statistically independent variables. Deflation-based implementations, such as the popular one-unit FastICA algo...
Optimal Designs for Two-Level Factorial Experemients
Generalized linear model full factorial design cylindrical algebraic decomposition D-optimality information matrix uniform design
2010/3/11
We consider the problem of obtaining locally D-optimal designs for factorial exper-
iments with qualitative factors at two levels each with binary response. For the 22
factorial experiment with main...
Prequential Plug-In Codes that Achieve Optimal Redundancy Rates even if the Model is Wrong
Prequential Plug-In Codes Optimal Redundancy Rates Model
2010/3/11
We analyse the prequential plug-in codes relative
to one-parameter exponential families M. We show that if data
are sampled i.i.d. from some distribution outside M, then the
redundancy of any plug-...
Strict Monotonicity and Convergence Rate of Titterington's Algorithm for Computing D-optimal Designs
D-optimality experimental design multiplicative algorithm
2010/3/9
We study a class of multiplicative algorithms introduced by Silvey et al. (1978) for com-
puting D-optimal designs. Strict monotonicity is established for a variant considered by
Titterington (1978)...
A Monte Carlo Algorithm for Universally Optimal Bayesian Sequence Prediction and Planning
recurrent neural network Turing machine AIXI reinforcement learning planning sequence prediction Universal prior
2010/3/9
The aim of this work is to address the question of whether we can in principle
design rational decision-making agents or artificial intelligences embedded
in computable physics such that their decis...
Asymptotic optimal designs under long-range dependence error structure
asymptotic optimal designs linear regression long-range dependence
2010/3/9
We discuss the optimal design problem in regression models with long-range dependence error
structure. Asymptotic optimal designs are derived and it is demonstrated that these designs
depend only in...
Optimal Sequential Kernel Detection for Dependent Processes
Enzyme kinetics financial econometrics nonparametric regression statis-tical genetics quality control
2010/3/9
In many applications one is interested to detect certain (known) patterns in
the mean of a process with smallest delay. Using an asymptotic framework which allows
to capture that feature, we study a...
Optimal rates of convergence for estimating the null density and proportion of nonnull effects in large-scale multiple testing
Optimal rates convergence null density proportion nonnull effects large-scale multiple testing
2010/3/9
An important estimation problem that is closely related to largescale
multiple testing is that of estimating the null density and the
proportion of nonnull effects. A few estimators have been introd...

On a general zero-sum stochastic game with optimal stopping
a general zero-sum stochastic game optimal stopping
2009/9/24
In the paper a general zeroaum stochastic game with
stopping is considered. Using the so-called penalty method the author
shows the existence of the value of the game under fairly general
assumptio...

A probabilistic approach to the reduite in optimal stopping
A probabilistic approach the reduite in optimal stopping
2009/9/23
In this work the approach to the reduite is made in
a simple and unified way. More precisely, we use the same probabilistic
technique to study the optimal stopping problem associated with
the redui...
