The main research topics of the DREAM project-team are about aiding monitoring and diagnosis of time evolving systems. The main issue is to infer the state of a system from observations provided by sensors in order to detect and characterize potential anomalies or failures within the system. We use a model-based approach relying on normal and faulty behavioral models. These models are temporal qualitative discrete-event models such as temporal communicating automata, temporal causal graphs or sets of chronicles.
- Automatic model acquisition. We investigate symbolic machine learning techniques such as ILP (Inductive Logic Programming).
- Diagnoser algorithm design and implementation.Relying on model inversion and compilation, these techniques aim at computing compact models which link directly observations to faults. More precisely, we focus on a decentralized and generic approach and on the use of model checking techniques.
- Diagnosis and decision interaction in an uncertain context.
- Cardiac monitoring Electrocardiogram on-line analysis, "intelligent" cardiac devices investigation: pacemakers and defibrillators.
- Environmental protection Improvement of land cover classification from remotely sensed images, qualitative modelling of pollutant (pesticides, nitrates) transfer in groundwater.
- Industrial diagnosis Supervision of telecommunication networks and power distribution systems.
International and industrial relations
- Participating in MONET2, the European Network of Excellence in Model-Based and Qualitative Reasoning Systems (BRIDGE working group).
- Collaborating with ANU (the Australian National University, Canberra). Contact: Sylvie Thiébaux.
- Collaborating with INRA (Institut National de la Recherche Agronomique - National Institute for Agricultural Research) in the Phyto project.
