Earlystopping用法
Web需要训练的有两个模型,一个是文本识别模型,一个是图像识别模型。在训练的时候,尝试了ResNet50、ResNet101、MobileNetV2,三种模型,前两个残差神经网络模型的参数比较大,训练比较耗时,精度上也逊… WebRegularization, in the context of machine learning, refers to the process of modifying a learning algorithm so as to prevent overfitting. This generally involves imposing some sort of smoothness constraint on the learned model. This smoothness may be enforced explicitly, by fixing the number of parameters in the model, or by augmenting the cost function as in …
