Existing weakly supervised sound event detection (WSSED) work has not explored both types of co-occurrences simultaneously, i. e., some sound events often co-occur, and their occurrences are usually accompanied by specific background sounds, so they would be inevitably entangled, causing misclassification and biased localization results with only clip-level supervision.
