Notes. Figure of merit (FoM) for different inference strategies: the convergence power spectrum C, the explicit full-field through HMC, the CNN map compressed statistics with the MSE, the VMIM, the MAE and the GNLL loss functions. The values of the FoM are inversely proportional to the area of the contours; the larger the FoM, the higher the constraining power.
