针对以上两点,该文的motivation就是能否设计一个自适应的且不需要超参数的reweighting方法,即找到一种从loss到weight的映射关系。 三 文章方法 Meta-Weighting-Net (MW-Net) 3.1 key idea 为了提出这样一个自适应的且不需要超参数的reweighting方法,文章的主要想法是用MLP来充当weight fucntion的作用,即让MLP自动学习...

作者说了现有的scalinglaw通常只预测loss,而不是特定的benchmark上的表现;(2)scalinglaw可能因基于小资源进行的预训练运行而变得没那么可靠。 对此,作者搞了一个两步走方法。 1.先建立计算最优模型在下游任务上的负对数似然与训练FLOPs之间的相关性。 2.利用scalinglaw模型和使用更高计算FLOPs训练的旧模型,将下游任...
machine learning中的其实就是weight组成的vector,通过梯度下降的方法,人为的调整learning rate,不断的迭代,从而训练出最好的weight Mata learning是由许多许多的task来组成的,其训练资料也是由许许多多的task组成的。下图的learning algorithm F就是我们要找的结果,其中meta learning的loss function,就是全部task的loss...

Sample re-weighting strategy is commonly used to alleviate this issue by designing a weighting function mapping from training loss to sample weight, and then iterating between weight recalculating and classifier updating. Current approaches, however, need manually pre-specify the weighting function as ...
