Abstract:
|
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.
