Weakly Supervised Sound Event Detection (WSSED), which relies on audio tags without precise onset and offset times, has become prevalent due to the scarcity of strongly labeled data that includes exact temporal boundaries for events.

We demonstrate that loss functions designed to address data imbalance in SED can effectively reduce the impact of noisy labels on system performance.
