title: DCASE 2024 Task 5: Few-shot Bioacoustic Event Detection Development Set

description: General Description:

The development set for task 5 of DCASE 2024 "Few-shot Bioacoustic Event Detection" consists of 217 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.

Annotation structure

Each line of the annotation csv represents an event in the audio file. The column descriptions are as follows:

TRAINING SET---------------------Audiofilename, Starttime, Endtime, CLASS_1, CLASS_2, ...CLASS_N

VALIDATION SET---------------------Audiofilename, Starttime, Endtime, Q

 

Classes

DCASE2024_task5_training_set_classes.csv and DCASE2024_task5_validation_set_classes.csv provide a table with class code correspondence to class name for all classes in the Development set. Additionally, DCASE2024_task5_validation_set_classes.csv also provides a recording names column.

DCASE2024_task5_training_set_classes.csv---------------------dataset, class_code, class_name

DCASE2024_task5_validation_set_classes.csv---------------------dataset, recording, class_code, class_name

 

Evaluation Set

The Evaluation set for this task will be released on the 1 June 2024
