Thomas Guyet

Assistant Professor in Computer Science - IRISA/LACODAM

Bio

I received my engineering diploma from Ecole Nationale Supérieure d'Informatique et de Mathématiques Appliquées de Grenoble, France (ENSIMAG) in image processing in 2004 and my PhD thesis in Computer Science in 2007 from National Polytechnic Institute of Grenoble. During my Phd ("Collaborative interpretation of time series. Application to intensive care data."), I worked in the Grenoble Informatic Laboratory (LIG) in a wide range of the artificial intelligence domain (cognitive science, data mining and applications) and in the TIMC Laboratory in a team that works in the applied field of cardio-respiratory physiology (PRETA).
From 2007 to now, I'm assistant professor at AGROCAMPUS OUEST and I'm working in the IRISA laboratory (LACODAM Team, previously DREAM) in Rennes. I was in partial secondment at Inria during 2015-2016.

Research interests

My research area is artificial intelligence (AI) with a multidisciplinary approach - algorithmic, design methodologies and cognitive science. I am particularly interested in discovering spatial and temporal patterns in semantically rich datasets. My areas of application are related to agronomy (mainly landscapes) and health (care pathways analysis).

My first research direction is the temporal and spatial pattern mining. Data from the observation of living systems (agricultural and medical systems) have a strong spatial or temporal dimension. But the spatial and temporal information is often underutilized in the data mining algorithms. The challenge lies in identifying new kind of temporal/spatial patterns that have valuable properties to make possible their extraction by complete and correct algorithms. A recent approach I'm developping is the use declarative programming, more especially Answer Set Programming (ASP) with clingo, to mix pattern mining and reasonning.
My second research direction aims at better including the user in the loop of knowledge discovery. Specifically, I am interested in implementing interactive systems to support users in their exploration process of large datasets. To acheive this goal I propose an enactive point of view of the data interpretation that brings creative solutions to take into account the cognitive ergonomy of the knowledge discovery tools.

Projects

Current projects in which I am strongly involved in

  • PEPS (Pharmaco-Epidemiology of Health Product) (2015-2019, ANSM) The main aims of this project is to make pharmacoepidemiological studies from the medico-administrative databases. These databases contains administrative information about the reimbursement of the 65 millions of french insured. I'm responsible of the scientific program of the IRISA partner. Our aim is to develop temporal pattern mining techniques for care pathway analysis.
  • SePaDec (Sequential Patterns with Declarative Approaches) (2015-2016, Région Bretagne) The aim of this project is to explore declarative approaches, especially Anwser Set Programming to extract sequential patterns. This project will be applied to deeply explore small sets of care pathways. The project is being carried out with B. Negrevergne.
