Quantum Distance Approximation for Persistence Diagrams

no code implementations27 Feb 2024 Bernardo Ameneyro, Rebekah Herrman, George Siopsis, Vasileios Maroulas

Topological Data Analysis methods can be useful for classification and clustering tasks in many different fields as they can provide two dimensional persistence diagrams that summarize important information about the shape of potentially complex and high dimensional data sets.

On the Computational Cost of Stochastic Security

no code implementations13 May 2023 Noah A. Crum, Leanto Sunny, Pooya Ronagh, Raymond Laflamme, Radhakrishnan Balu, George Siopsis

We investigate whether long-run persistent chain Monte Carlo simulation of Langevin dynamics improves the quality of the representations achieved by energy-based models (EBM).
