  Talk Title: Embracing Uncertainty in Geometric Data Analysis
  
  Series: CS Colloquium
  
  Abstract: Many methods dealing with data on geometric domains suffer from noise, nonconvexity, and other challenges because they are forced to make choices among nearly-indistinguishable possibilities. For instance, edge-preserving image filters must assign pixels near the boundary of an object to either its interior or its exterior, inheriting different colors, textures, and other properties depending on the particular outcome. In geometry processing, algorithms for registering scans of three-dimensional objects must break discrete (e.g. left-right) and continuous (e.g. cylindrical or translational) symmetries to settle on a single correspondence.
  
  In this talk, I will present techniques for explicitly acknowledging these and other ambiguities within graphics, imaging, and data processing pipelines. In particular, rather than making arbitrary tie-breaking decisions, these methods maintain distributions over potential outcomes. This “soft” probabilistic framework explicitly acknowledges challenging ambiguities and can be used to design robust techniques for processing and understanding images and shapes. In addition to introducing the relevant theory, I will show how it can be used to derive practical algorithms for photo processing, network analysis, and surface mapping.
  
  Biography: Justin Solomon is a PhD candidate in the Geometric Computing Group at Stanford University. He studies problems in graphics, learning, and imaging combining techniques from mathematical theory and computer science. His work has led to practical applications in geometry processing, computational photography, and medical imaging and is supported by the Hertz Foundation Fellowship, the NSF Graduate Research Fellowship, and the NDSEG Fellowship.
  
  Justin holds bachelors degrees in mathematics and computer science and a masters degree in computer science from Stanford. He is a dedicated instructor and has served as the lecturer for courses in graphics, differential geometry, and numerical methods. His forthcoming textbook entitled Numerical Algorithms focuses on applications of numerical methods to graphics, learning, and vision. Before beginning his graduate studies, Justin was a member of Pixar's Tools Research group. Outside the lab, he is a pianist, cellist, and amateur musicologist with award-winning research on early recordings of the Elgar Cello Concerto.

  There’s a hurricane blowing into the Ahmanson filled with glorious Gershwin melodies, rousing production numbers and one of theatre’s most unforgettable and timeless love stories. The legendary Porgy and Bess, ahead of its time in 1935, has come of age in a contemporary new adaptation deservedly celebrated with the 2012 Tony Award for Best Revival of a Musical. On Charleston’s Catfish Row, the livin’ ain’t easy for Bess, bound to one man and in love with another. At the heart of this tempest is a rich and rapturous score of Gershwin standards, including breathtaking classics like “Summertime,” “It Ain’t Necessarily So” and “I Got Plenty of Nothing.”
