Statistics Seminars: Nonparametric transformations for directional and shape data

Presented by Charles Taylor, University of Leeds

27 February 2017 14:00 in CM221

For i.i.d. data (x_i, y_i), in which both x and y lie on a sphere,
we consider flexible (non-rigid) regression models, in which
solutions can be obtained for each location of the manifold,
with (local) weights which are are function of distance. By considering
terms in a series expansion, a ``local linear'' model is proposed for
rotations, and we explore an iterative procedure with connections to
boosting. Further extensions to general shape matching are discussed.
