We advocate the use of curated, comprehensive benchmark suites of machine learning datasets, backed by standardized OpenML-based interfaces and complementary software toolkits written in Python, Java and R. We demonstrate how to easily execute comprehensive benchmarking studies using standardized OpenML-based benchmarking suites and complementary software toolkits written in Python, Java and R. Major distinguishing features of OpenML benchmark suites are (i) ease of use through standardized data formats, APIs, and existing client libraries; (ii) machine-readable meta-information regarding the contents of the suite; and (iii) online sharing of results, enabling large scale comparisons. As a first such suite, we propose the OpenML-CC18, a machine learning benchmark suite of 82 classification datasets carefully curated from the thousands of datasets on OpenML.
