现在需要会客制化的learning rate。 1、Root Mean Square 在θᵢ²这个方向上loss的变化比较大,所以算出来的gradient都比较大,σ就比较大;σ比较大,update的时候step就比较小。所以有了σ这一项以后呢,就可以随着gradient的不同来自动的调整learning rate的大小。但是这个有个问题:就算是同一个参数,它需要的lear...
RNN 均方根loss 有效值(root mean square) RMS值实际就是有效值,就是一组统计数据的平方的平均值的平方根。 RMS=(X1平方+X2平方+...+Xn平方)/n 的1/2次方。 在直流(DC)电路中,电压或电流的定义很简单,但在交流(AC)电路中,其定义就较为复杂,有多种定义方式。均方根(rms)指的是定义AC波的有效电压...

ValueError: Unknown loss function:root_mean_squared_error 原因:训练模型时的loss函数是自己定义的RMSE函数,如下: def root_mean_squared_error(y_true, y_pred): return K.sqrt(K.mean(K.square(y_pred - y_true), axis=-1)) 在此更正一下,RMSE 函数定义应该没有axis=-1,上面那个函数应该是定义的MA...
