Education
Jointly accredited by Paris Dauphine University and AgroParisTech.
The purpose of this academic background is to provide to the students the theoretical and practical needed for designing the future generations of complex computer systems, often distributed over a network for diagnostics, design and decision making. More specifically, the goal is to master the conceptual, semantic and algorithmic problems raised by the development of new software technologies associated with the Internet :
- Web services.
- Multi-agent systems.
- Advanced database systems.
- Data mining.
- Data warehouse.
These innovative technologies are applied to the development of software tools in the WEB:
- Mobile agents.
- Virtual companies.
- Assistant agents.
- Cooperative systems.
The objective is to train researchers of very high level prepared to acquire jobs in companies specialized in :
- Research and development (R&D) of applications.
- Big data.
- Information systems.
