TopoFisher: Learning Topological Summary Statistics by Maximizing Fisher Informationstat.ML

TopoFisher learns topological summaries by maximizing Fisher information, improving parameter efficiency and inference quality.

problem Simulation-based inference misses key information in low-order statistics, especially for non-Gaussian fields.
method TopoFisher uses a differentiable persistent-homology pipeline that learns topological summaries by maximizing local Gaussian Fisher information.
result TopoFisher recovers much of the available information and outperforms fixed topological vectorizations in weak gravitational lensing.
