2013-14: LDHD: Opening Workshop: September 8-12, 2013
Workshop Information
The Opening Workshop for this program was held Sunday - Thursday, September 8 - 12, 2013, at the Radisson Hotel Research Triangle Park, NC. The hotel is in close proximity to SAMSI.
On Sunday, September 8 there were tutorial lectures by leading researchers. From Monday to Wednesday, invited speakers addressed specific research topics relevant to Working Groups in the program, which were formed on Wednesday, September 11. A poster session and reception took place on Monday, September 9.
Immediately following the workshop, on Thursday and Friday, the Working Groups convened at SAMSI. In these meetings, each working group identified initial research activities and relevant datasets for the program year. These foci will, of course, evolve over the year, and Working Groups may either merge or emerge as research progresses.
The Opening Workshop provided an overview of the core topics relevant to the LDHD program, which is devoted to the development of methodological, theoretical, and computational treatment of high-dimensional mathematical and statistical models. For a more detailed description of the topics to be covered, see the LDHD homepage at http://samsi.info/LDHD.
