tsai 是一个用于时间序列分类、回归和预测的深度学习库。它基于 PyTorch 和 fastai 构建,提供了一个框架,用于为序列数据分配标签、预测单变量或多变量序列的未来值,并通过自监督学习在未标记数据上训练表征。 该库的特色在于其专业的时间工程和缩放能力。它包含用于捕捉季节性模式的周期性时间编码工具,以及用于处理超出内存限制数据集的在线窗口切片功能。它还支持多模态输入管道,能够将静态分类特征与动态连续序列相结合。 该工具包涵盖了广泛的预处理和评估需求,包括滑动窗口分割、缺失数据插补以及将表格数据帧转换为结构化张量。模型性能通过向前验证(walk-forward validation)和特征重要性分析进行评估,以确保时间一致性。
