1. Table 2, ℒB row
The published ℒB row contains subband-loss values from the seed-20 baseline run. The formally selected baseline run was seed 10, selected because it had the smallest final pixel-wise L2 loss among seeds 10, 20, and 30. Supplementary Table S9 records final PL2L values of 2.713, 2.931, and 3.009 × 10−3, respectively.
The published row is:
| Condition | SB1 | SB2 | SB3 | SB4 | SB5 | SB6 | SB7 |
|---|
| ℒB, published (seed 20) | 17.37 | 23.77 | 26.68 | 17.00 | 7.524 | 4.782 | 17.89 |
The corrected row, using the formally selected seed-10 run, is:
| Condition | SB1 | SB2 | SB3 | SB4 | SB5 | SB6 | SB7 |
|---|
| ℒB, corrected (seed 10) | 17.17 | 22.84 | 23.06 | 12.40 | 6.747 | 5.167 | 24.36 |
The correction changes only the numerical values in the Table 2 ℒB row. It does not change the caption, main text, conclusions, or the reported effect of SFL.
2. Vertical-axis exponents in Figure 4 and Supplementary Figure S3
| Location | Published | Correct |
|---|
| Fig. 4(b), vertical axis | ×10−5 | ×10−4 |
| Fig. 4(d), vertical axis | ×10−5 | ×10−4 |
| Supplementary Fig. S3(b), vertical axis | ×10−5 | ×10−4 |
| Supplementary Fig. S3(d), vertical axis | ×10−5 | ×10−4 |
Figure 4(a) and 4(c), and Supplementary Fig. S3(a) and S3(c), require no correction. The plotted data, interpretation, text, and conclusions are unchanged.
Supporting data and plotting scripts
The learning-curve data supporting the Table 2 correction and the gnuplot scripts used to reproduce the corresponding learning-curve figures are provided below. Both data files contain 75 rows for epochs 1 through 75. At epoch 75, columns 8 through 14 of the seed-20 data reproduce the published Table 2 values, whereas the same columns of the formally selected seed-10 data reproduce the corrected values shown above.
Learning-curve file format
Each learning-curve file is a whitespace-delimited text file with 15 columns. The Table 2 subband-loss values are taken from columns 8 through 14 at epoch 75.
| Column | Content |
|---|
| 1 | Epoch |
| 2 | Consistency loss |
| 3 | Pixel-wise L2 reconstruction loss (PL2L) |
| 4 | Quantizer loss |
| 5 | Codebook loss |
| 6 | Commitment loss |
| 7 | Weighted subband loss |
| 8 | Unweighted subband loss, SB1 |
| 9 | Unweighted subband loss, SB2 |
| 10 | Unweighted subband loss, SB3 |
| 11 | Unweighted subband loss, SB4 |
| 12 | Unweighted subband loss, SB5 |
| 13 | Unweighted subband loss, SB6 |
| 14 | Unweighted subband loss, SB7 |
| 15 | Feature reconstruction loss |
Although the final column reports the feature reconstruction loss, its weight was set to 0 throughout training. The value was logged only for monitoring and was not included in the training objective.
Reproducing the figures
Run each script from docs/corrigendum/scripts. The scripts read the corresponding file from ../data and write the L2-loss and subband-loss EPS figures to ../figures. The corrected vertical-axis exponent, ×10−4, is used for both subband-loss figures.
Provenance
The Table 2 correction is supported by the selected-run criterion reported in Supplementary Table S9 and by the publicly provided seed-10 and seed-20 learning-curve records. The seed-10 run is the formally selected baseline run. The seed-20 record is included to make the origin of the published Table 2 values directly verifiable.
