New(07-06-09)! Directions to the conference room and list of participants |
New(06-22-09)! The program of the workshop is now available |
Organizers: | Steve Oudot, Geometrica group, INRIA Saclay -- Île-de-France |
Leonidas Guibas, Geometric Computing group, Stanford University |
The Geometrica group at INRIA and the Geometric Computing group at Stanford University are organizing a joint workshop within the framework of their Associated Team TGDA. The goal of this workshop will be twofold:
Students are strongly encouraged to attend the workshop and take this opportunity to present their work. External contributions are encouraged as well, to enlarge the scope of the workshop to other areas of Science dealing with point cloud data, including (but not restricted to): Machine Learning, Networking, Applied Topology, and Applied Statistics. The first two days of the workshop (July 8-9) will be devoted to technical sessions and open to a general audience, while the last day (July 10) will be left for informal discussions among the members of the TGDA Associated Team.
Registration to the workshop is free but mandatory --- please register on or before June 10th 15th. If you are willing to give a talk, please select the corresponding option in the registration form and send your title and abstract to Steve Oudot on or before June 15th.

Address: 57, rue Lhomond, 5th district, Paris. To get there from Orly or Charles de Gaulle airport, take the RER line B (blue) to Luxembourg station, then walk up along Soufflot street, enter Ulm street and turn left into Lhomond street. Number 57 is pretty far down the road. To get there from anywhere else, take the metro or RER to Chatelet station, then take Metro line 7 to Censier-Daubenton, then walk up Daubenton and Mouffetard streets, then walk through the passage des postes to reach Lhomond street next to the entrance of the Institut des Systèmes Complexes. |
