Counterfactual contrastive learning enhances downstream task performance by incorporating domain-specific information through realistic image synthesis. The proposed CF-SimCLR method outperforms standard SimCLR by explicitly aligning domains in learned representations. Evaluation on chest radiography and mammography datasets shows significant improvements in robustness to acquisition shift, especially for under-represented domains. The lightweight counterfactual inference model used requires minimal computational overhead compared to the contrastive learning process.
