Reply to comment by mgostIH in Relative representations enable zero-shot latent space communication by 51616
From my understanding, the authors meant zero-shot communication (in the title) or stitching (in the text), where two NN components trained in different setups can be stitched together without further finetuning. This is just one useful application of the shared relative representation proposed in the paper.

Multiple reviewers pointed out that the empirical study is only limited to a modified ResNet and two datasets.

Reply to comment by florinandrei in [D] The MMSegmentation library from OpenMMLab appears to return the wrong results when computing basic image segmentation metrics such as the Jaccard index (IoU - intersection-over-union). It appears to compute recall (sensitivity) instead of IoU, which artificially inflates the performance metrics. by florinandrei
Pixels with
ignore_indexdoes not mean the model's output should also beignore_index. It means the groundtruth label is not determined on those pixels and whatever your model's output is, its correctness is undetermined.For those undetermined pixels, we simply ignore those outputs completely.
ignore_indexis not used to ignore a specific category during the metric calculation, which is what you're proposing.ignore_indexis simply notifyingintersect_and_unionsome areas of the image have undetermined labels and should be ignored, and those areas are marked by the value ofignore_index.
