From averaging to acceleration, there is only a step-size

We consider the optimization of a quadratic objective function whose gradients are only accessible through a stochastic oracle that returns the gradient at any given point plus a zero-mean finite variance random error. We present the first algorithm that a ...

Stream temperature prediction in ungauged basins: review of recent approaches and description of a new physics-derived statistical model

Michael Lehning, Marc Parlange, Bettina Schaefli, Aurélien Gallice

The development of stream temperature regression models at regional scales has regained some popularity over the past years. These models are used to predict stream temperature in ungauged catchments to assess the impact of human activities or climate chan ...

Graph network measures of brain connectivity and its relation with cognitive performance in high-risk children

Jean-Philippe Thiran, Elda Fischi Gomez, Djalel Eddine Meskaldji, François Lazeyras

Understanding rate and variability of connectivity in normal brain development can offer insight into the developmental origin of childhood and adult brain disorders. Indeed, there is increasing interest towards assessing the development of white matter (W ...

Quantitative Structure-Property Relationships for Thermal Stability and Explosive Properties of Chemicals

Thierry Meyer, Annik Nanchen, Francis Stoessel, Nadia Baati

Handling and storing chemicals in the industrial world require a conscientious hazards assessment and the implementation of appropriate measures to ensure safety for the workers, the company, the environment and the society. Reliable evaluations and predic ...

Stream Water Temperature Modeling For An Alpine Catchment

Vasco Andrea Neuhaus

Stream water temperature is an important key factor for water quality of rivers. Different approaches for stream temperature modeling have been developed over the past few decades and can basically be grouped into heat balance and stochastic models. Energy ...

A diffusion LMS strategy for parameter estimation in noisy regressor applications

Ali H. Sayed

We study distributed least-mean square (LMS) estimation problems over adaptive networks, where nodes cooperatively work to estimate and track common parameters of an unknown system. We consider a scenario where the input and output response signals of the ...

Physical and numerical model study investigating plunge pool scour at Kariba Dam

Anton Schleiss, Michael Pfister, Erik Bollaert, Rafael Xavier Meriade Duarte

Kariba Dam is a 128 m high arch dam located on the border between Zambia and Zimbabwe. The dam has been constructed in the late 1950s and formed at that time the largest man-made lake worldwide. The dam is equipped with 6 flood gates, each about 9 m high b ...

Multivariate Boosting with Look-Up Tables for Face Processing

Cosmin Atanasoaei

This thesis proposes a novel unified boosting framework. We apply this framework to the several face processing tasks, face detection, facial feature localisation, and pose classification, and use the same boosting algorithm and the same pool of features ( ...

Stratégies de compromis pour l'estimation des paramètres de régression et pour la classification floue

Nicolas Fournier

Model specification is an integral part of any statistical inference problem. Several model selection techniques have been developed in order to determine which model is the best one among a list of possible candidates. Another way to deal with this questi ...

Incremental Identification of Reaction and Mass-Transfer Rates In Gas-Liquid Reaction Systems Using Tendency Modeling

Dominique Bonvin, Nirav Pravinbhai Bhatt

The identification of reliable reaction and mass-transfer rates is important for building first-principles models of gas-liquid reaction systems. The identification of these rates involves the determination of a model structure (reaction stoichiometry, rat ...
