  • Preprint. The Missing Link: Finding label relations across datasets (arxiv), with Jasper & Vitto. Abstract: Computer Vision is driven by the many datasets which are available. However, each dataset has different set of class labels, visual definition of classes, images following a specific distribution, annotation protocols, etc. In this paper we want to understand how the instances of a certain class in a dataset relate to the instances of another class in another dataset. Are they in an identity, parent/child, overlap relation? Or is there no link between them at all? We conclude that label relations cannot be established by looking at the names of classes alone, as they depend strongly on how each of the datasets was constructed.
  • Preprint. How stable are transferability metrics? (arxiv) , with Andrea, Michal, Jasper & Vitto. Abstract: Transferability metrics aim to provide heuristics for selecting the most suitable source model to transfer to a given target dataset, without fine-tuning them all. Existing works, however, rely on custom experimental setups which differ across papers. In this paper we conduct a large-scale study by systematically constructing a broad range of 715k experimental setup variations. We discover that even small variations to an experimental setup lead to different conclusions about the superiority of a transferability metric over another
