Inference for Generalized Linear Models via Alternating Directions and Bethe Free Energy Minimization
Generalized linear models, where a random vector x is observed through a noisy, possibly nonlinear, function of a linear transform z = A x, arise in a range of applications in nonlinear filtering and regression. Approximate message passing (AMP) methods, b ...
IEEE2017Fréchet means in Wasserstein space
This work studies the problem of statistical inference for Fréchet means in the Wasserstein space of measures on Euclidean spaces, . This question arises naturally from the problem of separating amplitude and phase variation i ...

IEEE2015Gaze Evidence for Different Activities in Program Understanding
Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma, Marc-Antoine Nüssli
We present an empirical study that illustrates the potential of dual eye-tracking to detect successful understanding and social processes during pair programming. The gaze of forty pairs of programmers was recorded during a program understanding task. An a ...
2012The Effect of Scale on the Applicability of Taylor’s Frozen Turbulence Hypothesis in the Atmospheric Boundary Layer
Valentin Simeonov, Marc Parlange, Chad Higgins, Martin Froidevaux, Nikki Vercauteren, Caitlin Ellen Barry
Taylor’s frozen turbulence hypothesis is the central assumption invoked in most experiments designed to investigate turbulence physics with time resolving sensors. It is also frequently used in theoretical discussions when linking Lagrangian to Eulerian fl ...
2012Implementation of optimal Galerkin and Collocation approximations of PDEs with Random Coefficients
Fabio Nobile, Lorenzo Tamellini
In this work we first focus on the Stochastic Galerkin approximation of the solution u of an elliptic stochastic PDE. We rely on sharp estimates for the decay of the coefficients of the spectral expansion of u on orthogonal polynomials to build a sequence ...
2011Similarity solutions for solute transport in fractal porous media using a time-and scale-dependent dispersivity
A specific form of the Fokker–Planck equation with a time- and scale-dependent dispersivity is presented for modelling solute transport in saturated heterogeneous porous media. By taking a dispersivity in the form of separable power-law dependence on both ...
2005Semiclassical evaluation of quantum fidelity
We present a numerically feasible semiclassical (SC) method to evaluate quantum fidelity decay (Loschmidt echo) in a classically chaotic system. It was thought that such evaluation would be intractable, but instead we show that a uniform SC expression not ...
