Research Type Experimental Experiments on the hierarchical WN18RR knowledge graph show that our Poincaré embeddings outperform their Euclidean counterpart and existing embedding methods on the link prediction task, particularly at lower dimensionality.

Pseudocode No The paper does not contain a structured pseudocode or algorithm block.
Open Source Code Yes We implement both models in Py Torch and make our code, as well as all the subsets of the NELL-995 dataset, publicly available.2 https://github.com/ibalazevic/multirelational-poincare
Open Datasets Yes We implement both models in Py Torch and make our code, as well as all the subsets of the NELL-995 dataset, publicly available.2 https://github.com/ibalazevic/multirelational-poincare
Dataset Splits No The paper mentions using a 'validation set' but does not provide specific details on the dataset splits (e.g., exact percentages or sample counts for training, validation, and test sets).
Hardware Specification No The paper does not provide specific details about the hardware used for running experiments.
Software Dependencies No The paper mentions implementing models in 'Py Torch' but does not specify a version number for this or any other software dependency.
Experiment Setup Yes We choose the learning rate from {1, 5, 10, 20, 50, 100} by MRR on the validation set and find that the best learning rate is 50 for WN18RR and 10 for FB15k-237 for both models. (...) We set the batch size to 128 and the number of negative samples to 50. In all experiments, we set the curvature of Mu RP to c=1, since preliminary experiments showed that any material change reduced performance.
