Autre diplôme apprécié : Ecole d'ingénieur (computer science or engineering degree)

Fonction : Doctorant

Niveau d'expérience souhaité : Jeune diplômé

Contexte et atouts du poste

The objective of this project is to build embodied conversational agents (also known as ECAs, or virtual humans, or chatbots, or multimodal dialogue systems) that have the ability to engage their users in both social and task talk, where the social talk serves to improve task performance. In order to achieve this objective, we model human-human conversation, and integrate the models into ECAs, and then evaluate their performance.

This project is located at the prestigious computer science institute INRIA in downtown Paris. It takes place in the context of the PRAIRIE Institute for Interdisciplinary Research on AI - one of the four 3IA institutes launched by the French government in 2019. For more information see

Mission confiée

The doctoral student chosen for this project will acquire a broad range of skills in the analysis and synthesis of conversational behavior. S/he will build a corpus of data on the social aspects of human-human conversation within a particular domain, and annotate and analyze those data. He or she will derive computational models from the results of the data analysis as well as based on relevant prior literature, and refine those models using structural equation modeling and other tools. The doctoral student will integrate the computational models of social phenomena into a functioning ECA using machine learning approaches to dialogue systems, such as deep reinforcement learning and LSTM (among others), and will evaluate whether integrating the new models improves the performance of the ECA.  Applications of the work will be as varied as virtual personal assistants such as Alexa, Siri, and Google Now and intelligent tutoring systems.
