[Nicki Gotsis]

Ohad Fried will present his General Exam on Thursday, May 15, 2014 at 3pm in Rm. 402.  The members of his/her committee are Adam Finkelstein (advisor), Szymon Rusinkiewicz, Jianxiong Xiao.

Everyone is invited to attend his talk, and those faculty wishing to remain for the oral exam following are welcome to do so.  His abstract and reading list follow below.

Abstract:
---------
Collections of objects such as images are often presented visually in a grid because it is a compact representation that lends itself well for search and exploration. Most grid layouts are sorted using very basic criteria, such as date or filename. We present a method to arrange collections of objects respecting an arbitrary distance measure. Pairwise distances are preserved as much as possible, while still producing the specific target arrangement which may be a 2D grid, the surface of a sphere, a hierarchy, or any other shape.  We show that our method can be used for infographics, collection exploration, summarization, data visualization, and sound exploration. We present a fast algorithm that can work on large collections and quantitatively evaluate how well distances are preserved.
