Network analysis. We assess Encoder with different numbers of subnetworks $C$. We also analyze Decomposer and Detector variants using ordinary (OLS) or weighted least squares (WLS), varying the warp resolution $\varrho$ and number of output feature maps $k$, respectively. A value of ${\varrho }^{-1}=4$ , for example, means the warp ${\varphi }_{\theta }$ has resolution and dimensions of only 25% compared to the input images. Dice scores are averages over 100 UKBB cross-subject 2D pairs. Shaded areas indicate the standard error of the mean.
