SUMMARY:"Learning magnetic field structure from trajectories"\, Plasma
  Physics (Physics/ECE/NE 922) Seminar\, David Bindel\, Cornell Univers
 ity
DESCRIPTION:The magnetic fields in stellarators can be organized into 
 different regions according to the dynamics of field line flows\, with
  regions of nested flux surfaces potentially interspersed with islands
  or regions of chaos.  While can visualize these structures with Poinc
 are plots\, such visualizations are not wholly satisfactory if we wish
  to numerically optimize such structures.  In this talk\, we describe 
 an approach to automatically inferring the structure of magnetic field
  line flows by building models of the dynamics of field line trajector
 ies with connections to dynamical systems theory\, numerical extrapola
 tion methods\, and the theory of adaptive filtering. <br />Joint work 
 with Max Ruth (UT Austin).
