我不知道为什么我会得到这么好的结果。

我的训练和标签集是 [-0.05, 0.05] 范围内的浮点数数组，我正在使用Keras.sequential.model.lstm. 为什么会发生这种情况？以前，我在这里遇到了相反的问题：loss/val_loss 正在减少，但 LSTM 中的准确度是相同的！，但我无法理解这个问题。
编辑：我改变了我的代码：
model.compile(optimizer = 'adam', loss = 'mean_square_error', metrics=['accuracy'])
到：
model.compile(optimizer = 'adam', loss = 'mean_absolute_error', metrics=['accuracy'])
但结果是一样的。
然后我将上面的代码行更改为：
model.compile(optimizer = 'adam', loss = 'mean_squared_error', metrics=['mean_squared_error'])
但它没有用，结果如下：
