Dataset listing

The univariate and multivariate classification problems are available in three formats: Weka ARFF, simple text files and aeon ts format. Weka does not allow for unequal length series, so the unequal length problems are all padded with missing values. ts format does allow for this feature.

Univariate Weka formatted ARFF files and .txt files (about 500 MB).

Univariate aeon formatted ts files (about 300 MB).

Multivariate Weka formatted ARFF files (and .txt files) (about 2 GB).

aeon formatted ts files (about 1.5 GB).

Lists of the data, including which are unequal length, can be found here. You can load data directly from this website using the aeon toolkit. pip install aeon, then run:

from aeon.datasets import load_classification
X, y, meta_data = load_classification("GunPoint", meta_data=True)
print(" Shape of X = ", X.shape)
print(" Meta data = ", meta_data)

More details on loading are in this notebook . which is part of the aeon documentation

Lists of these datasets are available in the datasets module

More information on the datasets is given below. Problems with variable length series are listed as length 0.
