An ablation test can evaluate the effect of bottleneck size on classification accuracy and reconstruction quality. Experiment results obtained via ROI halving. Subplot (a) shows per-category classification accuracy for training and test sets for both halves, while (b) evaluates the patch-wise MSE and average spectral MSE between original and reconstructed patches. Finally, (c) shows reconstructions for different bottleneck sizes. Bottleneck clamping allows the use of a single autoencoder for this experiment. The rest of the coordinates are set to zero and the reconstruction is extracted at its output. A high-resolution version of (c) is provided in the Supplementary Material.
