Modeling dominance effects on nonverbal behaviors using granger causality

Daniel Gatica-Perez, Oya Aran, Dinesh Babu Jayagopi

In this paper we modeled the effects that dominant people might induce on the nonverbal behavior (speech energy and body motion) of the other meeting participants using Granger causality technique. Our initial hypothesis that more dominant people have gene ...

Bridging the Past, Present and Future: Modeling Scene Activities From Event Relationships and Global Rules

Jean-Marc Odobez, Rémi Emonet, Jagannadan Varadarajan

This paper addresses the discovery of activities and learns the underlying processes that govern their occurrences over time in complex surveillance scenes. To this end, we propose a novel topic model that accounts for the two main factors that affect thes ...

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 ...

Causal evidence for the involvement of the neural cell adhesion molecule, NCAM, in chronic stress-induced cognitive impairments

Maria del Carmen Sandi Perez, Reto Bisaz

In rodents, chronic stress induces long-lasting structural and functional alterations in the hippocampus, as well as learning and memory impairments. The neural cell adhesion molecule (NCAM) was previously hypothesized to be a key molecule in mediating the ...

Modelling human perception of static facial expressions

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

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 ...

Causal semantics for the algebra of connectors

Joseph Sifakis, Simon Bliudze

The Algebra of Connectors AC(P) is used to model structured interactions in the BIP component framework. Its terms are connectors, relations describing synchronization constraints between the ports of component-based systems. Connectors are structured comb ...

Dynamic facial expression recognition with a discrete choice model

Michel Bierlaire, Javier Cruz Mota, Thomas Robin

We propose a dynamic facial expression recognition framework based on discrete choice models (DCM). We model the choice of a person who has to label a video sequence representing a facial expression. The originality is based on the explicit modeling of cau ...

The Effect of Energy Efficiency Enhancement on Innovation and Competitiveness

Philippe Thalmann, Camille Gonseth

Our results lend support to the Porter Hypothesis and provide a clue to the underlying mechanism. We try to get at the causal effect of energy prices on TFP using a set of observations made annually on a large number of manufacturing industries located in ...
