Web2 days ago · Finally, the probability of the group-velocity dispersion curves (Fig. 1 c) can be assigned to each pixel of the group-velocity dispersion spectrograms by the sigmoid function (Table 1). We employ the cross-entropy loss function ( Formula 2 ) to rapidly update the weight and bias as follows: (2) L = − y log y ' + 1 − y log 1 − y ' where y represents the …
