On Euclid-like Gaussian mocks, likelihood-free inference stays well-calibrated under emulator error and non-Gaussian summaries, while explicit Gaussian-likelihood inference becomes miscalibrated and can disagree with a CNN probe by factors up to two.

Comparing explicit likelihood and likelihood-free simulation-based inference for weak lensing cosmic shear
On Euclid-like Gaussian mocks, likelihood-free inference stays well-calibrated under emulator error and non-Gaussian summaries, while explicit Gaussian-likelihood inference becomes miscalibrated and can disagree with a CNN probe by factors up to two.
