SUMMARY:Tutte Colloquium - Shachar Lovett
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Point Location and Active Learning - Learni
 ng Halfspaces\nAlmost Optimally\n\nSpeaker:\n Shachar Lovett\n\nAffiliatio
 n:\n UC San Diego\n\nZoom:\n Please email Emma Watson\n\nABSTRACT:\n\nThe
  point location problem is a central problem in computational\ngeometry. I
 t asks\, given a known partition of R^d by n hyperplanes\,\nand an unknown
  input point\, to find the cell in the partition to which\nthe input point
  belongs. The access to the input is via linear\nqueries. A linear query i
 s specified by an hyperplane\, and the result\nof the query is which side 
 of the hyperplane the input point lies in.\n
