title: DCASE 2021 Task 5: Few-shot Bioacoustic Event Detection Development Set

description: <strong>General Description</strong> The development set for task 5 of DCASE 2021 "Few-shot Bioacoustic Event Detection" consists of 19 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. <strong>Folder Structure</strong> <em>Development_Set.zip</em> |_Development_Set/ |__Training_Set/ |___BV/ |____*.wav |____*.csv |___HT/ |____*.wav |____*.csv |___JD/ |____*.wav |____*.csv |___MT/ |____*.wav |____*.csv |__Validation_Set/ |___HV/ |____*.wav |____*.csv |___PB/ |____*.wav |____*.csv <em>Development_Set_Audio.zip</em> has the same structure but contains only the *.wav files. <em>Development_Set_Annotations.zip</em> has the same structure but contains only the *.csv files <strong>Dataset statistics</strong> Some statistics on this dataset are as follows, split between training and validation set and their sub-folders: -----------------------------------------------------<br> TRAINING SET<br> -----------------------------------------------------<br> Number of audio recordings | 11<br> Total duration | 14 hours and 20 mins<br> Total classes (excl.
