Distribution of the Fisher information (detF) across the prior volume, for all summaries considered in this work. For the IMNN summary, we used the weights that give the highest median value (corresponding to 90k epochs; see Fig. 6). On the top axis we denote the corresponding relative improvement in the single parameter variance (Eq. (26)), normalized to its median value of the 2DPS summary. The 2DPS has the largest median value of all of the individual summaries, while the combination of the 2DPS + IMNN dramatically outperforms every individual summary. See Table 1 for quantitative values.
