Researchers have investigated methods to prevent catastrophic forgetting in sound event classification tasks using incremental learning. The study analyzed architectural and regularization approaches, focusing on protecting network kernels from weight updates and employing a dynamic head classifier that expands with new tasks. Findings indicate that catastrophic forgetting primarily affects deeper layers, particularly the classifier head. For in-domain sound classification, freezing the feature extractor and fine-tuning the dynamic head classifier proved most effective, demonstrating minimal forgetting, stable training, and a good balance between memory retention and learning adaptability.
