有一个类似的疑问,擦掉Grad-CAM生成的attention region之后,attention mining loss是使剩下的部分尽可能不被分到c类,想达到使Grad-CAM生成更大的attention map,感觉这个作用很间接啊。比如像“虎猫”这种类,只有头是最discriminative分到猫的,其他部分像老虎,这个loss更是加大了分类网络mining出其他部分的难度。 2018...

在这项工作中,我们主要使用梯度加权的类激活映射(Grad-CAM)作为显著性方法。根据给定的模型预测,它基于反向传播到后面的卷积层的梯度来生成特定于类的显著性映射。 4. Experience Packing and Replay (EPR) Experience Replay Experience Packing Factor (EPF) ...

对于GradCam可视化,我们将目标(需要在GradCam计算期间最大化)设置为当前和未来动作预测的负动作损失。请注意,GradCam通过计算梯度以最大化目标来可视化输入图像中对预测很重要的区域。它并不表示模型确实聚焦或很好地捕捉了GradCam突出显示的区域。如图3所示,用于当前动作预测的GradCam热图(a0)聚焦于接近自当前车辆位置...
