(2)Dice Loss比较适用于样本极度不均的情况,一般的情况下,使用 Dice Loss 会对反向传播造成不利的影响,容易使训练变得不稳定。 所以在一般情况下,还是使用交叉熵损失函数。 PyTorch参考代码 import torch.nn as nn import torch.nn.functional as F
https://github.com/shuxinyin/NLP-Loss-Pytorch 数据不均衡问题也可以说是一个长尾问题,但长尾那部分数据往往是重要且不能被忽略的,它不仅仅是分类标签下样本数量的不平衡,实质上也是难易样本的不平衡。 解决不均衡问题一般从两方面入手: 数据层面:重采样,使得参与迭代计算的数据是均衡的; ...
The following time comparisons were conducted using Deep Supervision and NoMirroring on an NVIDIA RTX 3090 24GB GPU. The environment was set up with Python 3.10.9, PyTorch 2.2.2, and CUDA 12.1. Additionally, cucim-cu12 and cupy==12.3 were utilized for GPU-accelerated distance transforms inMON...
I'm also transitioning into pytorch and I like that it seems more flexible in terms of setting up custom metrics or loss functions. I am using the tiramisu architecture for semantic segmentation which uses negative log likelihood as the loss (implementation here: https://github.com/bfortuner/py...
DiceLoss ohem 总结: PSENet是文本检测网络。 GitHub - whai362/PSENet: Official Pytorch implementations of PSENet. 首先我想说一句,这个PSENet写的模块,代码都非常好,非常值得学习。 每一部分: backbone + neck + head + post_precessing + loss 摘要 目前的文本检测有2个挑战: 1)基于anchor检测的方法,对任意...
And the reason is that label_smoothing is introduced after 1.9.1, could you please add a check and only send it to CrossEntropyLoss after 1.9.1. https://github.com/pytorch/pytorch/blob/v1.10.0/torch/nn/modules/loss.py Something like: MONAI/monai/engines/trainer.py Line 186 in 6608...
