We introduce MONSTER-the MONash Scalable Time Series Evaluation Repository-a
collection of large datasets for time series classification. The field of time
series classification has benefitted from common benchmarks set by the UCR and
UEA time series classification repositories. However, the datasets in these
benchmarks are small, with median sizes of 217 and 255 examples, respectively.
In consequence they favour a narrow subspace of models that are optimised to
achieve low classification error on a wide variety of smaller datasets, that
is, models that minimise variance, and give little weight to computational
issues such as scalability. Our hope is to diversify the field by introducing
benchmarks using larger datasets. We believe that there is enormous potential
for new progress in the field by engaging with the theoretical and practical
challenges of learning effectively from larger quantities of data.
