Etudes de potentiels évoqués sur le traitement de l'accord en langue orale (or ""ERP studies on oral langage processing of agreement"" (en Français)) by Phaedra Royle (École d'orthophonie et d'audiologie, Université de Montréal) Afin d'étudier l'acquisition du traitement de l'accord en genre en français, nous avons développé une étude de potentiels évoqués (PÉs) ayant une […]

Is lexical selection by competition ? by Robert Hartsuiker (Ghent University) There are several contrasting views on the mechanisms of lexical selection in language production. On one view, words compete with each other for selection, so that the time to select one word depends on the activation of competitors. This competitive view is often thought […]

Prosodic Constraints on Children's Variable Production of Grammatical Morphemes by Katherine Demuth (Macquarie University, New South Wales, Australia) Language acquisition researchers have long observed that children's early use of grammatical morphemes is highly variable. It is generally thought that this is due to incomplete syntactic or semantic representations. However, recent crosslinguistic research has found that […]

Synergie in Language Acquisition by Mark Johnson (Macquarie University, New South Wales, Australia) Each human language contains an unbounded number of different sentences. How can something so large and complex possibly be learnt? Over the past decade and a half we've learned how to define probability distributions over grammars and the linguistic structures they generate, […]

What Freud got right about speech errors by Gary S. Dell (University of Illinois, Urbana-Champaign, USA) Most people associate Sigmund Freud with the assertion that speech errors reveal repressed thoughts, a claim that does not have a great deal of support. I will mention some other things that Freud said about slips, showing that these, […]

The main goal of this aspect of the project was to produce a large-scale database in […]

Apprentissage par renforcement : de la modélisation des processus neuraux aux applications robotiques by Medhi Khamassi (l'Institut des Systèmes Intelligents et de Robotique (UPMC)) L'activité phasique des neurones dopaminergiques est considérée depuis une quinzaine d'années comme le substrat neural de signaux d'erreur de prédiction de la récompense (RPE). Ces signaux se sont avérés très proches […]

Apprentissage par renforcement (direct et inverse) pour les systèmes interactifs by Olivier Pietquin (SequeL team, University Lille 1, LIFL CNRS UMR 8022, INRIA Lille) L'apprentissage par renforcement est une catégorie d'apprentissage automatique qui se différencie des autres par le fait qu'elle a pour objectif l'optimisation d'une séquence de décisions, prenant en compte l'aspect temporel et […]
