Dataset for Sequence-to-sequence deep learning for improved lead detection during polar night using ICESat-2 data

This is sample data for Sequence-to-sequence deep learning for lead detection during polar night using ICESat-2 data. -Koo_sequence_sample.npy: ready-to-train sequence data for Koo dataset. -Liu_sequence_sample.npy: ready-to-train sequence data for Liu dataset. The original annotated labels in the Koo dataset are from Koo et al. (2023). https://www.sciencedirect.com/science/article/abs/pii/S0034425723002778 The original annotated labels in the Liu dataset are from Liu et al. (2025). https://www.sciencedirect.com/science/article/abs/pii/S0034425725000112本数据集为利用ICESat-2数据开展极夜时段冰间水道（lead）探测的序列到序列深度学习研究的示例数据。 - `Koo_sequence_sample.npy`：适用于Koo数据集的可直接用于训练的序列数据。 - `Liu_sequence_sample.npy`：适用于Liu数据集的可直接用于训练的序列数据。 Koo数据集的原始标注标签源自Koo等（2023）的研究，相关论文链接：https://www.sciencedirect.com/science/article/abs/pii/S0034425723002778 Liu数据集的原始标注标签源自Liu等（2025）的研究，相关论文链接：https://www.sciencedirect.com/science/article/abs/pii/S0034425725000112
