Auto Seg-Loss 希望(在语义分割任务上)将这个流程自动化。简单来说,我们发现主流的语义分割指标(基本由TP/TN/FP/FN组成)都能写成可微运算(比如加、乘)、量化(one-hot)和logical运算(与AND、或OR)的形式。由于logical运算实际上只定义在{0,1}x{0,1}上,我们使用一个参数化的曲面对logical运算进行插值,使得其...
因此,代理损失函数的设计需要expertise以及较高的试错成本;即便如此,设计出的代理损失函数有许多也不足以独当一面,需要和CE Loss联合训练才能达到不错的效果。 Auto Seg-Loss 希望(在语义分割任务上)将这个流程自动化。简单来说,我们发现主流的语义分割指标(基本由TP/TN/FP/FN组成)都能写成可微运算(比如加、乘)...

Box2Seg: Attention Weighted Loss and Discriminative Feature Learning for Weakly Supervised SegmentationWe propose a weakly supervised approach to semantic segmentation using bounding box annotations. Bounding boxes are treated as noisy labels for the foreground objects. We predict a per-class attention ...
We propose a weakly supervised approach to semantic segmentation using bounding box annotations. Bounding boxes are treated as noisy labels for the foreground objects. We predict a per-class attention map that saliently guides the per-pixel cross entropy
Linux代码中,NextSeg()的逻辑不再直接包含传统的三次重传机制。取而代之,当一个报文被发送后,即使没有完成重传,发送端也会根据延迟策略(如Nagle算法)自动决定何时发送新报文。这种改变源于RACK机制的高效性,它在Linux2.4版本的某个commit中被优化,删除了传统的步骤3(重传未标记的报文)。这个...
