Yossi Bokor

Research Interests

My current research interest is Geometric and Topological Data Analysis, and my PhD supervisor's are Dr Kate Turner and Professor Stephan Tillmann. I completed a Bachelor of Arts (Honours) at the University of Sydney, and my Honours Thesis was in Algebraic Geometry, supervised by Dr Emma Carberry, after which I completed a Master of Mathematical Sciences at ANU.

In particular, I am intersted in questions focusing on object recovery and object classification. These questions arise naturally in many areas of science, in particular biology.

  • Code

  • Skyler is Julia package which identifies the coarsest abstract graph structure underlying a point cloud, and modells it. Currently, we are restricted to graphs with linear edges which satisfy conditions detailed below. See the paper 'Reconstructing linearly embedded graphs: A first step to stratified space learning'.
  • DiscretePersistentHomologyTransform is a Julia package for calculating the Persistent Homology Transform.
