Bottleneck size experiment. Reconstruction loss decreases with increasing size of the bottleneck. However, once a certain threshold of dimensions is reached (at 46 dimensions), the loss stops improving rapidly and only slowly decreases when adding more dimensions to the bottleneck. In red, we show a polynomial of degree 4 that was fit on the data for illustrative purposes. Note that odd bottleneck sizes are rounded up (e.g., 45 becomes 46) to create an even-dimensional feature space for downstream tasks.
