d65f6ec3ce 减少训练过程中的输出频率
修改了训练脚本,将训练过程中的进度输出频率从每批输出改为每100批输出一次,以减少输出量,提高训练效率。
2024-10-06 22:16:42 +08:00
87fa4dfcc6 增加了INN部分的残差连接模块,修改了训练和测试代码以提高代码的可读性和可维护性。- 在train.py中添加了打印所有参数的代码,以方便检查和记录 2024-10-06 22:12:47 +08:00

Drop paths (Stochastic Depth) per sample (when applied in main path of residual blocks).
This is the same as the DropConnect impl I created for EfficientNet, etc networks, however,
the original name is misleading as 'Drop Connect' is a different form of dropout in a separate paper...
See discussion: https://github.com/tensorflow/tpu/issues/494#issuecomment-532968956 ... I've opted for
changing the layer and argument names to 'drop path' rather than mix DropConnect as a layer name and use
'survival rate' as the argument.
