uea_ucr_datasets

This package contains convenience functions and classes to access the UEA UCR time series classification archive.

Currently it contains the following functionalities:

• Dataset class: Loads UEA UCR dataset stored in the sktime format from ~/.data/UEA_UCR/ or path provided via the UEA_UCR_DATA_DIR environment variable. This class is compatible with the pytorch DataLoader class.
• list_datasets: List datasets available in the ~/.data/UEA_UCR/ folder or path provided via the UEA_UCR_DATA_DIR

Example usage

Download the sktime version of the UEA and UCR datasets. And unpack them. Move the folders of the individual datasets to the path ~/.data/UEA_UCR.

>>> import uea_ucr_datasets
>>> uea_ucr_datasets.list_datasets()
['LSST',..]
>>> d = uea_ucr_datasets.Dataset('UWaveGestureLibrary', train=True)
>>> first_instance = d[0]
>>> instance_x, instance_y = first_instance

Alternative data paths

You can also store the data at another location, then it is required to set the environment variable UEA_UCR_DATA_DIR appropriately such that the package can find the datasets.
