Topological Learning for Motion Data via Mixed Coordinates

Hengrui Luo, Jisu Kim, Alice Patania +1

Topology can extract the structural information in a dataset efficiently. In this paper, we attempt to incorporate topological information into a multiple output Gaussian process m…

An improved algorithm for Generalized Čech complex construction

Jie Chu, Mikael Vejdemo-Johansson, Ping Ji

In this paper, we present an algorithm that computes the generalized Čech complex for a finite set of disks where each may have a different radius in 2D space. An extension of this…

Generalized Penalty for Circular Coordinate Representation

Hengrui Luo, Alice Patania, Jisu Kim +1

Topological Data Analysis (TDA) provides novel approaches that allow us to analyze the geometrical shapes and topological structures of a dataset. As one important application, TDA…

3d-printing Identification Spaces of the Square

Mikael Vejdemo-Johansson

We describe three identification spaces of the square, interesting choices of immersion into , and a process to construct 3d-printable models of their parametrization…

Multiple testing with persistent homology

Mikael Vejdemo-Johansson, Sayan Mukherjee

In this paper we propose a computationally efficient multiple hypothesis testing procedure for persistent homology. The computational efficiency of our procedure is based on the ob…
