This is my implementation of Dice Loss: Hi@IssamLaradji, for some reason I never got to reply. I am sorry. These codes are actually doing something very similar but they have small differences: The Dice ratio in my code follows the definition presented in the paper I mention; (the differ...
使用target network这个trick在Deep RL中用的相当广泛,最开始提出的原因是因为minimize TD error的过程和minimize supervise learning loss的过程不同,TD error一般是\| r(s, a) + \gamma V_\theta(s') - V_\theta(s) \|^2,虽然也可以理解成缩小r(s, a)和V_\theta(s) - \gamma V_\theta(s')之...

For detailed implementation, see theget_weightsfunction. Time Comparisons 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 ...
I am using the tiramisu architecture for semantic segmentation which uses negative log likelihood as the loss (implementation here: https://github.com/bfortuner/pytorch_tiramisu). The results so far are great. I highly recommend using this architecture for semantic segmentation. Have not tried it ...
Beside the ignore_index, I think the dice loss implementation has it own logical problem as well. The output_preds has shape [bs, num_classes, H, W] but the target's shape is [bs, H, W], which is cannot be the same shape when flattenning. I think the target has to pass through...
The Jaccard, Dice and Tversky losses in losses._functional are modified based on JDTLoss. Since Jaccard and Dice losses are special cases of the Tversky loss [1], the implementation is simplified by calling soft_tversky_score when calculating both jaccard_score and dice_score. The original loss...
First loss function, supporting TensorFlow and PyTorch with equal implementations and quantitative results. Original TensorFlow implementation was written by @innat which was built on top of. Thank...
