Research Type Experimental We study the performance of our regularizer Hy Co Re on the synthetic dataset Model Net40 [27] (12,331 objects with 1024 points, 40 classes) and on the real dataset Scan Object NN [28] (15,000 objects with 1024 points, 15 classes).

Pseudocode No The paper does not contain any clearly labeled pseudocode or algorithm blocks. Methods are described in prose.
Open Source Code Yes Code of the project: https://github.com/diegovalsesia/HyCoRe
Open Datasets Yes We study the performance of our regularizer Hy Co Re on the synthetic dataset Model Net40 [27] (12,331 objects with 1024 points, 40 classes) and on the real dataset Scan Object NN [28] (15,000 objects with 1024 points, 15 classes). We use standard datasets and splits well known by the literature and report all values of the hyperparameters for our tests.
Dataset Splits Yes We use standard datasets and splits well known by the literature and report all values of the hyperparameters for our tests.
Hardware Specification Yes Models are trained on an Nvidia A6000 GPU.
Software Dependencies No The paper states:
Experiment Setup Yes We use f = 256 features to be comparable to the official implementations in the Euclidean space, then we test the model over different embedding dimensions in the ablation study. Moreover, we set α = β = 0.01, γ = 1000 and δ = 4. For the number of points of each part N , we select a random number between 200 and 600, and for the whole object a random number between 800 and 1024 to ensure better flexibility of the learned to model to part sizes. We train the models using Riemannian SGD optimization.
