Abstract: Highlights•We proposed PXgboost classifier for classifying Hyperbolic dataset.•We proposed EPboost classifier which ensembles Euclidean and Hyperbolic space•We verify our approach using 64 standard ML datasets and 8 WordNet datasets.•We made a conversion map via Sammon mapping to visualize Hyperbolic data in Euclidean space.
