Web9 de ago. de 2024 · The proposed dynamic methods make better utilization of multi-scale training loss without extra computational complexity and learnable parameters for backpropagation. Experiments show that our approaches can consistently boost the performance over various baseline detectors on Pascal VOC and MS COCO benchmark. WebWhile debugging, I noticed that the loss_scale starts from the default max value and then goes all the way down to 1.0; I'm guessing because it detected the nan gradients. But then even at a loss scale of 1.0, I'm still not getting any reduction in loss. Any ideas or thoughts here would be greatly appreciated. thanks! dui ambulance driver crashes into ditch

Web(2) 我们需要把loss放大 (这也是我们在config里面需要指定的scale)。为什么呢？ (1)里面讲过虽然我们更新已经用FP32来计算了，但是存储仍然还是用的FP16的。如果梯度很小（这个由于激活函数的存在其实是非常常见的），那么FP16的比特数根本不足以表达到这么精确，梯度就都变成0了。所以把loss放大，梯度也会跟着放大，即可用FP16存储了。 (3) … Web26 de abr. de 2024 · We propose a Dynamic Scale Training paradigm (abbreviated as DST) to mitigate scale variation challenge in object detection.
