A Unified Loss Function to Tackle Inter-Class and Intra-Class Data Imbalance in Sound Event Detection
ICASSP 2024accepted
Data imbalance is an important issue in data-driven deep-learning methodologies. In sound event detection (SED), there are two types of data imbalance issues caused by the diverse time duration of sound events: the data imbalance between sound event classes (inter-class imbalance) and the active/ina…
