Researchers have developed a novel two-stage training pipeline to improve Automatic Chord Recognition (ACR) models, addressing the scarcity of labeled data. The method first uses a pre-trained model as a teacher to generate pseudo-labels for a large dataset of unlabeled audio. A student model is then trained on these pseudo-labels, with knowledge distillation from the teacher model employed to prevent catastrophic forgetting. This approach significantly enhances ACR performance, outperforming traditional supervised learning baselines and even the original pre-trained teacher model, particularly for rare chord qualities.
