Title: Beyond Summary Statistics: Leveraging Generative Models for Field-Level Weak Lensing Analysis
Outline
Field-level cosmological inference
Simulation-based inference
Normalizing flows
- Transform the distribution of data
and a normal distribution through a series of invertible transformations . - To make the sample easier.
Results
Power spectrum analysis can only extract the Gaussian information, whereas the field-level analysis can leverage the non-Gaussian information.
