### Datasets |
|
|
|
#### Train |
|
- Exclusively using focal audio data from Xeno-Canto (XC) with quality ratings A, B, C and excluding all recordings that are CC-ND. |
|
- Each dataset is tailored for specific target species identified in soundscape files. |
|
- We offer detected events and corresponding cluster assignments to identify bird sounds in each recording. |
|
- We provide the full recordings from XC! These can generate multiple samples from a single instance. |
|
|
|
#### Test |
|
- Only soundscape data sourced from Zenodo. |
|
- We provide the full recording with the complete label set and specified bounding boxes. |
|
- This dataset excludes recordings that do not contain bird calls ("no_call"). |
|
- Task: Multiclass ("ebird_code") |
|
|
|
#### Test_5s |
|
- Only soundscape data from Zenodo formatted acoording to the Kaggle evaluation scheme. |
|
- Each recording is segmented into 5-second intervals without overlaps. |
|
- This contains the "no_call" class. |
|
- Task: Multilabel ("ebird_code_multilabel") |
