Statistical distributions of trace metal concentrations in the northwestern Mediterranean atmospheric aerosol

The concentrations of 11 crustal and anthropogenic trace metals (Li, Al, V, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb) were measured from 2006 to 2008 in the atmospheric aerosol at a northwestern Mediterranean coast (station of Cap Ferrat, situated on the southeaster ...

Modeling the behavior of investors

Michel Bierlaire, Thomas Robin

We introduce a hybrid discrete choice framework to model the decisions of investors in stock markets. More specifically, we model the decision to buy or sell stocks using a binary logit model with latent classes, characterizing the perception of risk. The ...

Dynamic facial expression recognition with a discrete choice model

Michel Bierlaire, Javier Cruz Mota, Thomas Robin

A generation of new models has been proposed to handle some complex human behaviors. These models account for the data ambiguity, and there- fore extend the application field of the discrete choice modeling. The facial expression recognition (FER) is highl ...

New Challenges in Disaggregate Behavioral Modeling : Emotions, Investments and Mobility

Thomas Robin

This thesis tackles new challenges associated with the disaggregate modeling of the human behavior. Decision-aid tools help in making decisions, by providing quantitative insights on the decisions and associated consequences. They are useful in complex sit ...

Modelling human perception of static facial expressions

Michel Bierlaire, Jean-Philippe Thiran, Gianluca Antonini, Javier Cruz Mota, Thomas Robin, Matteo Sorci

A recent internet based survey of over 35'000 samples has shown that when different human observers are asked to assign labels to static human facial expressions, different individuals categorize differently the same image. This fact results in a lack of a ...

Specification, estimation and validation of a pedestrian walking behavior model

Michel Bierlaire, Gianluca Antonini, Javier Cruz Mota, Thomas Robin

We propose and validate a model for pedestrian walking behavior, based on discrete choice modeling. Two main types of behavior are identified: unconstrained and constrained. By unconstrained, we refer to behavior patterns which are independent from other i ...

Decrease of lead concentrations in the Western Mediterranean atmosphere during the last 20 years

Thomas Robin

Concentrations of lead (Pb) in the atmospheric aerosol were monitored in 198687, 199293, 1995, 199798 and 20032005 at a North-Western Mediterranean coastal sampling station. After the implementation of antipollution policies on automotive Pb in the second ...
