A new research paper published on arXiv details a comparison of parallel heterogeneous ensemble methods for tabular classification tasks. The study analyzed 56 small-to-medium tabular classification tasks from OpenML CC18, leading to a set of best practice recommendations. These recommendations were validated on 28 additional tasks using TabArena data, where they significantly outperformed the Single Best method and matched or exceeded individual ensemble methods. Key findings include the independent inconsistencies of Blending and Stacking methods, and the particular success of Robust Soft Voting, especially in multiclass scenarios. AI
