(1995-04-19)
loss: n. Something ( not a person) that loses; a situation in which something is losing. Emphatic forms include moby loss, and total loss, complete loss. Common interjections are “ What a loss!” and “ What a moby loss!” Note that moby loss is OK even though ** moby loser is not used; applied to an abstract noun, moby is simply a magnifier, whereas when applied to a person it implies substance and has positive connotations. Compare lossage. LOSS, contracts. The deprivation of something which one had, which was either advantageous, agreeable or commodious. 2. In cases of partnership, the losses are in general borne by the partners equally, unless stipulations or circumstance' s manifest a different intention. Story, Partn. Sec. 24. But it is not essential that the partners should all share the losses. They may agree, that if there shall be no profits, but a loss, that the loss shall be borne by one or more of the partners exclusively, and that the others shall, inter se, be exempted from all liabilities for losses. Colly. Partn. 11; Gow, Partn. 9; 3 M. & Wels. 357; 5 Barn. & Ald. 954 Story, Partn. Sec. 23. 3. When a thing sold is lost by an accident, as by fire, the loss falls on the owner, res perit domino, and questions not unfrequently arise, as to whether the thing has been delivered and passed to the purchaser, or whether it remains still the property of the seller. See, on this subject, Delivery.

- 深度学习的loss一般收敛到多少？ - 知乎
看题主的意思，应该是想问，如果用训练过程当中的loss值作为衡量深度学习模型性能的指标的话，当这个指标下降到多少时才能说明模型达到了一个较好的性能，也就是将loss作为一个evaluation metrics。 但是就像知乎er们经常说的黑话一样，先问是不是，再问是什么。所以这个问题有一个前提，就是
- 有哪些「魔改」loss函数，曾经拯救了你的深度学习模型？ - 知乎
类似的Loss函数还有IoU Loss。 如果说DiceLoss是一种 区域面积匹配度 去监督网络学习目标的话，那么我们也可以使用 边界匹配度去监督网络的Boundary Loss。 我们只对边界上的像素进行评估，和GT的边界吻合则为0，不吻合的点，根据其距离边界的距离评估它的Loss。
- 深度学习中loss和accuracy的关系? - 知乎
loss 的具体形式取决于机器学习任务的类型。 例如，在回归问题中，常用的 loss 函数包括平方损失、绝对损失和对数损失；在分类问题中，常用的 loss 函数包括交叉熵损失和 Hinge 损失。
- 深度学习的多个loss如何平衡？ - 知乎
多个loss引入 pareto优化理论，基本都可以涨点的。 例子： Multi-Task Learning as Multi-Objective Optimization 可以写一个通用的class用来优化一个多loss的损失函数，套进任何方法里都基本会涨点。反正我们在自己的研究中直接用是可以涨的。
- 究竟什么是损失函数 loss function? - 知乎
如何设计loss函数？ Loss函数和你任务的评价准则越相关，二者越接近越好。 如果你任务的评价准则是F1-score（不可导），但一直在使用CrossEntropy Loss来迭代模型，二者之间虽然相关性很高但仍存在非线性。 如何在Pytorch中使用loss函数？
- 深度学习的loss一般收敛到多少？ - 知乎
深度学习的loss一般收敛到多少？ 计算机视觉的图像L2损失函数，一般收敛到多少时，效果就不错了呢？ 显示全部 关注者 111
- 求通俗易懂解释下nce loss？ - 知乎
Tensorflow实现了两种常用与word2vec的loss，sampled softmax和NCE，这两种loss本身可以用于任意分类问题。 之前一直不太懂这两种方法，感觉高深莫测，正好最近搞懂了，借tensorflow的代码和大家一起分享一下我的理解，也记录一下思路。
- keras深度学习框架输出acc loss,val_acc val_loss，什么意思？
上图就是一个很典型的过拟合现象，训练集的 loss 已经降到0了，但是验证集的 loss 一直在上升，因此这不是一个很好的模型，因为它太过拟合了。 如果我们非要用这个模型，应该在5~10代的时候停止训练，这个操作叫提前停止，是正则化方法之一。
- 强化学习中actor_loss和critic_loss收敛问题？ - 知乎
在正常的训练过程中，actor_loss和critic_loss的减小趋势表明模型在不断学习和优化。 若在训练过程中发现actor_loss持续增大，这可能意味着Actor未能有效学习到优化策略，或者Critic的反馈不够准确，导致Actor的更新方向出现偏差。
