内置训练

使用内置训练函数为序列和表格数据训练深度学习网络

定义网络架构后，您可以使用 trainingOptions 函数定义训练参数。然后，您可以使用 trainNetwork 训练网络。使用经过训练的网络预测类标签或数值响应，或预测将来的时间步。

您可以在一个 CPU、一个 GPU、多个 CPU 或 GPU 上训练神经网络，或者在集群中并行训练或在云中训练。在 GPU 上训练或并行训练需要 Parallel Computing Toolbox™。使用 GPU 需要支持的 GPU 设备（有关受支持设备的信息，请参阅GPU Computing Requirements (Parallel Computing Toolbox)）。使用 trainingOptions 函数指定执行环境。
