本文属于较为传统的机器学习领域,研究的也是相对而言比较基础和 fundamental 的问题,即 SGD optimizer 在机器学习模型中的 implicit regularization。也就是说,正常情况下,我们可以通过在loss function 后面加一项 regularizer 来保证我们找到的解是相对较好的,然而我们在用了SGD算法时,可以在无 regularizer 的情况下达到相...

keras model.compile(loss='目标函数 ', optimizer='adam', metrics=['accuracy']) 目标函数,或称损失函数,是网络中的性能函数,也是编译一个模型必须的两个参数之一。由于损失函数种类众多,下面以keras官网手册的为例。 在官方keras.io里面,有如下资料: ...
