1. Loss值能否作为衡量模型性能的指标 之所以说几乎不能,是因为对于分类问题,模型的loss值与咱们关心的模型指标(metrics)有一定的相关性,但不是绝对相关,所以loss值本身不能作为模型的衡量指标;而对于回归问题,loss值具有一定的指导意义,但是不如人为设计出来的metrics那么直观,所以也. 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。 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 牛津高阶上,给出的用法是be at a loss for words 和i'm at a loss what to do next 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。
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?
深度学习当中train loss和valid loss之间的关系? 深度学习当中train loss和valid loss之间的关系,在一个caption实验当中,使用交叉熵作为损失函数,虽然随着训练,模型的评价指标的… 显示全部 关注者 35 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。 Dispersive Loss 的目的: 是最大化表示的 分散性。 当不进行 \ell_2 归一化时,特征向量的 范数(长度) 是被允许自由变化的。 如果模型为了最小化 Dispersive Loss,它会倾向于让特征向量的范数变得非常大。
