Abstract

The OpenML repository is widely employed by the Machine Learning (ML) community, storing a large number of datasets along with the results of com-putational experiments run on the same data. Some meta-analysis of ML datasets are also provided in the MATILDA repository (Melbourne Algorithm Test Instance Library with Data Analytics). The objective of this work is to analyze meta-datasetsgenerated from such repositories joining the characteristics of the OpenML datasets and also the performance achieved by different ML techniques in their solution, in order to support meta-learning tasks.
