IOS、Python自学心得30天 Day-17 learning rate

前言:
经过多次的测试和训练
val_accuracy 在最後几乎都是处於0.6500左右的状态
所以这次我想从optimizer着手
也许是收敛过早的问题

net_final.compile(optimizer=Adam(learning_rate=0.001, beta_1=0.9, beta_2=0.999, epsilon=1e-08),
                  loss='categorical_crossentropy', 
                  metrics=['accuracy'])

104/104 [==============================] - 128s 1s/step - batch: 51.5000 - size: 63.6154 - loss: 4.1122 - accuracy: 0.1167 - val_loss: 3.2964 - val_accuracy: 0.2344
