General Description:
The development set for task 5 of DCASE 2022 "Few-shot Bioacoustic Event Detection" consists of 209 audio files acquired from different bioacoustic sources. The dataset is split into training and validation sets.
Multi-class annotations are provided for the training set with positive (POS), negative (NEG) and unkwown (UNK) values for each class. UNK indicates uncertainty about a class.
Single-class (class of interest) annotations are provided for the validation set, with events marked as positive (POS) or unkwown (UNK) provided for the class of interest.
