Datasets#

autrainer provides a number of different audio-specific datasets, base datasets for different tasks, and toy datasets for testing purposes.

Tip

To create custom datasets, refer to the custom datasets tutorial.

A dataset configuration file should include the following attributes, in addition to the common attributes like id, _target_, and dataset-specific attributes inferred from the constructors:

Structure and Loading

  • path: The directory path to the dataset, containing the features_subdir directory and the train.csv, dev.csv, and test.csv files.

  • features_subdir: The subdirectory within the dataset directory where (extracted) features are stored. If different from default and set to the name of a preprocessing transform, autrainer preprocess will save the processed data in the specified subdirectory with the same name.

  • index_column: The column in the CSV files that contains paths to the audio files, relative to the dataset subdirectory.

  • target_column: The column in the CSV files that contains the targets or labels.

  • file_type: The type of the files to load (e.g., wav, npy).

  • file_handler: The file handler to use for loading the data.

Training and Evaluation

  • criterion: The criterion to use for training.

  • metrics: A list of metrics to evaluate the model.

  • tracking_metric: The metric to track for early stopping and model selection.

  • transform: The online transforms to apply to the data and the output type of the dataset.

To avoid race conditions when using Launcher Plugins that may run multiple training jobs in parallel, autrainer fetch and autrainer preprocess or fetch() and preprocess() are used to download the dataset and preprocess the data before training.

Note

All datasets that are provided by autrainer can be automatically downloaded as well as optionally preprocessed using the autrainer fetch and autrainer preprocess CLI commands or the fetch() and preprocess() CLI wrapper functions.

Load the dataframes.

Return type:

Tuple[DataFrame, DataFrame, DataFrame]

Returns:

Dataframes for training, development, and testing.

static download(path)[source]#

Download the FAU AIBO dataset.

As the AIBO dataset is private, this method does not download the dataset but rather prepares the file structure expected by the preprocessing routines.

In the specified path, the following directories and files are expected:

  • default/: Directory containing .wav files.

  • chunk_labels_2cl_corpus.txt: File containing the file names and corresponding labels for the 2-class classification task.

  • chunk_labels_5cl_corpus.txt: File containing the file names and corresponding labels for the 5-class classification task.

Produces the following splits for both tasks (2cl and 5cl):

  • train_{task}.csv: Training split of all speakers of the Ohm-Gymnasium with the exception of the last two speakers.

  • dev_{task}.csv: Development split of the last two speakers of the Ohm-Gymnasium.

  • test_{task}.csv: Test split of all speakers of the Montessori-Schule.

For more information on the dataset and dataset split, see: https://doi.org/10.1109/ICME51207.2021.9428217

Parameters:

path (str) – Path to the directory to download the dataset to.

Return type:
