3 months ago 可以调节loss中以下部分就可以实现:
loss_1 = (self.intra_fd(f1)+self.intra_fd(f2)+self.intra_fd(f3)+self.intra_fd(f4))/4
loss_1 += (self.intra_fd(f1_0)+self.intra_fd(f2_0)+self.intra_fd(f3_0)+self.intra_fd(f4_0))/4
loss_1 += (self.intra_fd(f1_d_0)+self.intra_fd(f2_d_0)+self.intra_fd(f3_d_0))/3
loss_1 += (self.intra_fd(f1_d)+self.intra_fd(f2_d)+self.intra_fd(f3_d))/3
loss_2 = (self.inter_fd(f1_d,final_layer)+self.inter_fd(f2_d,final_layer)+self.inter_fd(f3_d,final_layer)
+self.inter_fd(f1,final_layer)+self.inter_fd(f2,final_layer)+self.inter_fd(f3,final_layer)+self.inter_fd(f4,final_layer))/7
loss_2 += (self.inter_fd(f1_d_0,final_layer)+self.inter_fd(f2_d_0,final_layer)+self.inter_fd(f3_d_0,final_layer)
+self.inter_fd(f1_0,final_layer)+self.inter_fd(f2_0,final_layer)+self.inter_fd(f3_0,final_layer)+self.inter_fd(f4_0,final_layer))/7
loss = loss_1 * self.lambda_1 + loss_2 * self.lambda_2
return loss

请问在代码中，该如何更改两个loss的平衡超参数呢，您在论文的消融实验部分分析到 λ1 = 0.015 和 λ2 = 0.015 是最佳配置。
