Embedded dataset in Poincare Balls

This dataset contains four real-world sub-datasets with data embedded into Poincare ball models, including Olsson's single-cell RNA expression data, CIFAR10, Fashion-MNIST and mini-ImageNet. Each sub-dataset has two corresponding files: one is the data file, the other one is the pre-computed reference points for each class in the sub-dataset. Please refer to our paper (https://arxiv.org/pdf/2109.03781.pdf) and codes (https://github.com/thupchnsky/PoincareLinearClassification) for more details.

本数据集包含四个嵌入于庞加莱球模型中的现实世界子数据集，其中包括奥尔斯松的单细胞RNA表达数据、CIFAR10、Fashion-MNIST以及mini-ImageNet。每个子数据集均对应两个文件：其一为数据文件，其二为子数据集中各类别的预计算参考点。请参阅我们的论文（https://arxiv.org/pdf/2109.03781.pdf）及代码（https://github.com/thupchnsky/PoincareLinearClassification）以获取更多详细信息。
