Web4 1.3 Minimizing the MSE Notice that (yTx T)T = Tx y. Further notice that this is a 1 1 matrix, so y Tx = xTy. Thus MSE( ) = 1 n yTy 2 TxTy+ TxTx (14) 1.3 Minimizing the MSE First, we nd the gradient of the MSE with respect to : rMSE( = 1 n ryTy 2r TxTy+ r TxTx (15) = 1 n 0 2xTy+ 2xTx (16) = 2 n xTx xTy (17) We now set this to zero at the ...

WebOne supposed problem with SMAPE is that it is not symmetric since over- and under-forecasts are not treated equally. This is illustrated by the following example by applying the second SMAPE formula: Over-forecasting: A t = 100 and F t = 110 give SMAPE = 4.76% it helpdesk report templateWebOne supposed problem with SMAPE is that it is not symmetric since over- and under-forecasts are not treated equally.
