Researchers explored the use of synthetic facial images to improve deep learning models for recognizing rare genetic syndromes. They found that while synthetic oversampling generally improved accuracy, the benefits were modest and varied across different disorders and model architectures. An analysis of model embeddings showed that disorders with fewer real training images tended to gain more class separation, but this did not always correlate with improved classification performance. The study suggests that synthetic data can be beneficial for limited-data facial phenotyping but highlights the need to carefully assess the amount and impact of augmentation for specific disorders and model setups.
