Brief Abstract for the Paper


Domain generalization (DG) utilizes multiple labeled source datasets to train a generalizable model for unseen target domains. However, due to expensive annotation costs, the requirements of labeling all the source data are hard to be met in real-world applications.

We investigate a Single Labeled Domain Generalization (SLDG) task with only one source domain being labeled, which is more practical and challenging than the Conventional Domain Generalization (CDG). A major obstacle in the SLDG task is the discriminability-generalization bias: discriminative information in the labeled source dataset may contain domain-specific bias, constraining the generalization of the trained model.

To tackle this challenging task, we propose Domain-Specific Bias Filtering (DSBF), which initializes a discriminative model with the labeled source data and filters out its domain-specific bias with the unlabeled source data for generalization improvement. We divide the filtering process into: (1) Feature extractor debiasing using k-means clustering-based semantic feature re-extraction; and (2) Classifier calibrating using attention-guided semantic feature projection.

Requirements

You may need to build suitable Python environment by installing the following packages (Anaconda is recommended).

  • python 3.6
  • pytorch 1.7.1 (with cuda 11.0 and cudnn 8.0)
  • torchvision 0.8.2
  • tensorboardx 2.1
  • numpy 1.19
