Abstract


Domain Generalization techniques aim to enhance model robustness by simulating novel data distributions during training typically through various augmentation or stylization strategies. However these methods frequently suffer from limited control over the diversity of generated images and lack assurance that these images span distinct distributions. To address these challenges we propose FDS Feedback-guided Domain Synthesis a novel strategy that employs diffusion models to synthesize novel pseudo-domains by training a single model on all source domains and performing domain mixing based on learned features. By incorporating images that pose classification challenges to models trained on original samples alongside the original dataset we ensure the generation of a training set that spans a broad distribution spectrum. Our comprehensive evaluations demonstrate that this methodology sets new benchmarks in domain generalization performance across a range of challenging datasets effectively managing diverse types of domain shifts.
