Title: Finding cosmic filament by the directional ridge finding algorithm
Author(s): Yikun Zhang and Yen-Chi Chen*
Companies: University of Washington, Seattle and University of Washington
Keywords: filaments; astrostatistics; ridge; optimization

In this talk, we present a new method for finding cosmic filaments in the Sloan Digital Sky Survey based on a directional ridge finding approach. This method improved the usual subspace constraint mean-shift algorithm to the directional data scenario. Moreover, we will provide both statistical and computational guarantees of this new method.

Authors who are presenting talks have a * after their name.
