Robin T., Bierlaire M. (2012). Modeling the behavior of investors. Journal of Choice Modelling 5 (2)

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 model considers the dynamic nature of the underlying decision process and is estimated from the data of a Swiss bank containing 25989 transactional observations from January 2005 to September 2010 for 6 different portfolios. The predictive performance of the model is tested: a cross-validation analysis is performed and the forecasting accuracy of the model is studied in details. Parameters of the model are interpretable and quantify interesting behavioral mechanisms related to investors’ decisions. The predictive capabilities of the model in a real context makes it practicable.

Robin T., Bierlaire M., Cruz J. (2011). Dynamic facial expression recognition with a discrete choice model. Journal of Choice Modelling 4 (2):95-148

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 highly relevant in this context. We develop a dynamic facial expression recognition (DFER) framework based on dis- crete choice models (DCM). The DFER consists in modeling the choice of a person who has to label a video sequence representing a facial expression. The originality is based on the the analysis of videos with discrete choice models as well as the explicit modeling of causal effects between the facial features and the recognition of the expression. Five models are proposed. The first assumes that only the last frame of the video triggers the choice of the expression. The second model has two components. The first captures the perception of the facial expression within each frame in the sequence, while the second determines which frame triggers the choice. The third model is an extension of the second model and assumes that the choice of the expression results from the average of perceptions within a group of frames. The fourth and fifth models integrate the panel effect inherent to the estimation data and are respectively extensing the first and second mod- els. The models are estimated using videos from the Facial Expressions and Emotions Database (FEED). Labeling data on the videos has been obtained using an internet survey available at http://transp-or2.epfl.ch/videosurvey/. The prediction capability of the models is studied in order to check their validity by cross-validation using the estimation data.

Sorci M., Antonini G., Cruz J., Robin T., Bierlaire M., Thiran J. (2010). Modelling human perception of static facial expressions. Image and Vision Computing 28 (5):790-806

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 an unique ground-truth, an assumption held by the large majority of existing models for classification. This is especially true for highly ambiguous expressions, especially in the lack of a dynamic context. In this paper we propose to address this shortcoming by the use of Discrete Choice Models (DCM) to describe the choice a human observer is faced to when assigning labels to static facial expressions. Different models of increasing complexity are specified to capture the causal effect between features of an image and its associated expression, using several combinations of different measurements. The sets of measurements we used are largely inspired by FACS but also introduce some new ideas, specific to a static framework. These models are calibrated using maximum likelihood techniques and they are compared with each other using a likelihood ratio test, in order to test for significance in the improvement resulting from adding supplemental features. Through a cross-validation procedure we assess the validity of our approach against overfitting and we provide a comparison with an alternative model based on Neural Networks for benchmark purposes.

Robin T., Antonini G., Bierlaire M., Cruz J. (2009). Specification, estimation and validation of a pedestrian walking behavior model. Transportation Research Part B: Methodological 43 (1):36-56

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 individuals. The constrained patterns are captured by a leader-follower model and by a collision avoidance model. The spatial correlation between the alternatives is captured by a cross nested logit model. The model is estimated by maximum likelihood estimation on a real data set of pedestrian trajectories, manually tracked from video sequences. The model is successfully validated using a bi-directional flow data set, collected in controlled experimental conditions at Delft university.

Migon C., Robin T., Dufour A., Gentili B. (2008). Decrease of lead concentrations in the Western Mediterranean atmosphere during the last 20 years. Atmospheric Environment 42 :815-821

Concentrations of lead (Pb) in the atmospheric aerosol were monitored in 1986–87, 1992–93, 1995, 1997–98 and 2003–2005 at a North-Western Mediterranean coastal sampling station. After the implementation of antipollution policies on automotive Pb in the second half of the 1980s, Pb concentrations were markedly lowered and then the decrease slowed down, at the latest in 2003, resulting in average concentrations varying between 6.6 and 5.8 ngm3 in 2004 and 2005, respectively. This represents a decrease by a factor of 82%, approximately, between 1986–87 and 2005. Reproducible seasonal patterns are observed, with highest Pb loads occurring at the end of winter and at the end of summer/beginning of autumn. The slowing down of aerosol Pb concentration decrease in the troposphere is expected to be rapidly observed in the Western Mediterranean water column.

Destination choice models for a free bicycle system, Zehra Onen (Mathematics)

Supervision: Ricardo Hurtubia, Thomas Robin
Several cities around the world are implementing �free bicycle systems� that consist of a network of stations were bicycles are available for users to �pay and ride�. Usually these systems allow users to return the bicycle in a different station from the one where it was taken. The project consists in estimating destination choice models that should allow to predict the station where a bicycle will be returned, given the origin, the time of the day, the length (in time) of the trip and the characteristics of the surroundings of each station. The project considers 3 main stages: Data analysis, model estimation (with the software BIOGEME) and model validation.

Simulateur de mouvements de piétons, Viljami Laurmaa (Mathematics)

Supervision: Thomas Robin, Javier Cruz, Mamy Fetiarison
Les mod�les de mouvement de pi�tons permettent de simuler le comportement de foules. Ils sont utiles dans le domaine de la s�curit�, de l'�vacuation, mais �galement pour la plannification urbaine. En effet de nos jours pour des raisons environementales, de nombreux centres-ville sont interdits aux voitures et transform�s en zones pi�tonnes. Ces mod�les servent � simuler le comportement des pi�tons dans des contextes urbains pr�d�finis afin de choisir l'am�nagement qui sera le mieux adapt�. Ce projet concerne l'impl�mentation d'un mod�le de mouvements de pi�tons, mod�le d�velopp� � l'EPFL au sein du laboratoire Transp-or

Finance and Discrete Choice Models, Inès Azaiez (Mathematics)

Supervision: Thomas Robin
Default risk evaluation for credit cards and mortgages, credit ratings determination, probabilities estimation of acquisitions and mergers of firms (used to guide investment), are very complex financial tasks. They require a very good expertise of the field. This is due to the high number of information that decision makers need to account for. In addition, information could be very heterogeneous in term of source and impact on the decision itself. Models can help financial decision maker in their tasks. For instance, classification methods are mainly used to model financial decisions. Discrete Choice Models (DCM) have been successively applied to many fields in the past 40 years, such as transportation or marketing. Compared to machine learning methods they have the advantages to explicitly model causal relations between dependant variables and exogenous attributes, and to avoid data over-fitting. DCMs start to be used in the financial field. The aim of this project is to investigate DCM use in a financial context, then find relevant problem to which it can be applied and finally illustrate those concepts on a real case study.

Mode choice modelling with qualitative aspects inclusions, Zehra Onen (Mathematics)

Supervision: Thomas Robin
Discrete Choice Models (DCM) are widely used in transportation to explain mode choice. Objective attributes have been commonly used to describe the different alternatives, such as travel time or travel cost. Kaufmann et al. (2001) have conducted some transportation mode choice surveys. In addition to the classical data collection, they have included questions about experiences and perceptions of transportation modes. The obtained database is large and contains lots of respondents sociological aspects, difficult to apprehend in a classical DCM, due to their qualitative nature. In order to go through such issues, J.L.Walker (2001) has proposed a new modelling framework based on DCM and latent concepts. She used schemes to describe links between variables. The aim of the project is to identify complex causal links between sociological aspects and transportation mode choice, based on the data cited above, and then derive a new modelling framework.

Expérience des moyens de transport et choix modal, Seyed Tavakoli (Civil Engineering)

Supervision: Michel Bierlaire, Thomas Robin
Lorsque l�on choisit d�utiliser un moyen de transport plut�t qu�un autre, ind�pendamment des temps de d�placements et des co�ts compar�s des alternatives en pr�sence, l�usager a des pr�f�rences. Celles-ci sont li�es � son exp�rience des moyens de transport et � la perception qu�il en a. Les mod�lisations du choix modal ne rendent qu�imparfaitement compte de cette dimension, intrins�quement qualitative. Pour la traiter, le LaSUR a d�velopp� depuis une dizaine d�ann�es un dispositif de citation d�adjectifs, appliqu� � de gros �chantillons de population lors d�enqu�tes de mobilit�. Nous proposons comme sujet de Master de mod�liser sur la base des donn�es disponibles, l�impact de l�exp�rience sensorielle des moyens de transports sur le choix modal.

Analysis of consumer behaviour in terms of product preference/choice., Aurélie Glerum (Mathematics)

Supervision: Thomas Robin, Michaël Thémans
This project will be conducted in collaboration with the Nestl� Research Center. Quantitative studies are frequently used in the food industry in order to determine whether a product is superior to its competitor(s). Many types of studies exist, but this project focuses on a specific type of study involving only two products and in which consumers are asked to evaluate both products with regard to different criteria (such as flavour, appearance, texture, etc.) and to choose the product they prefer. Socio-demographic characteristics as well as information on consumption habits are also collected during the test. The aim of this project is to explore a database containing about 100 studies that have been conducted over the past years on a same product category in different countries. Such studies are usually analyzed by the means of descriptive statistics in order to answer the two following questions: -Which product do consumers prefer? -Why do consumers prefer this product? In this project, we propose to analyze the studies by making use of discrete choice modelling. This technique allows understanding and modelling the behaviour of consumers in a quantitative way when they are exposed to such choice situations, i.e. the choice between two products. Discrete choice models should allow identifying and quantifying the effect of both product attributes and consumer characteristics on the preference.

Est-il possible de réduire le nombre de panélistes dans une étude DTS (Dominance Temporelle des Sensations) sans altérer la qualité des résultats?, Glerum Aurélie (Mathematics)

Supervision: Thomas Robin, Michaël Thémans
La m�thode de la Dominance Temporelle des Sensations (DTS) permet de suivre l��volution des perceptions sensorielles en bouche au cours de la mastication d�un produit alimentaire. Elle consiste simplement � demander au pan�liste de s�lectionner la caract�ristique dominante du produit au cours de la mastication. Par exemple, si le produit est une barre de c�r�ales, le pan�liste doit indiquer au cours de la mastication d�une bouch�e si le produit est plut�t croquant, friable, collant ou p�teux. Cette caract�ristique dominante peut changer au cours du temps. Sur l�ensemble du panel, cette m�thode permet de dessiner les courbes d��volution de chaque descripteur sensoriel au cours du temps. Cette m�thode est relativement r�cente et les premi�res �tudes ont �t� r�alis�es avec un nombre de pan�listes tr�s important (environ 50 �valuations de chaque produit). L�objectif de ce projet est de tester si cette m�thode donne des r�sultats aussi satisfaisants avec un nombre de pan�listes r�duit. Le travail consistera donc � : se familiariser avec la m�thode DTS et la construction des courbes, d�velopper un programme permettant de construire ces courbes pour un sous-ensemble de pan�listes, g�n�rer les r�sultats pour plusieurs tailles de panel en utilisant les donn�es de plusieurs �tudes DTS existantes au centre de recherche Nestl�, proposer une m�thode pour comparer les r�sultats des panels de taille r�duite avec le panel complet, appliquer cette m�thode et analyser les r�sultats, r�diger un rapport pr�sentant la d�marche et mettant en avant les principales conclusions.

Modèle de choix discret, Weber Caroline (Mathematics)

Supervision: Thomas Robin
Les mod�les de choix de discret sont tr�s pertinents concernant le choix de mode de transport. Une enqu�te sur les trajets a �t� men�e d�ao�t � d�cembre 2003 par l�ETHZ, � Frauenfeld et ses abords dans le canton de Thurgovie, en Suisse. Celle-ci concerne 230 personnes, suivies pendant 6 semaines et provenant de 99 m�nages. L��tude de la base de donn�es r�sultante permettra de mieux conna�tre les habitudes des voyageurs, ainsi que de d�velopper un mod�le de choix de mode de transport. Le but de ce projet est de s�initier � l�analyse des mod�les de choix discret leurs applica- tions sur des donn�es r�elles, en l�occurence les donn�es d�crites ci-dessus.
