Step3: 使用SoftDataset对student network进行fine-tune CVPR2018: Joint Optimization Framework for Learning with Noisy Labels 只使用噪声数据 通过实验给出结论:较大学习率下,网络不易过拟合于噪声数据 提出模型参数和样本标签同时优化的方法,在每一次迭代中做两个更新: Step1: 固定样本标签,更新模型参数 Step2: ...
这次的 paper reading,聚焦 Learning with noisy label: 有一定量的标注数据。-- 通过搜索引擎、公开数据集等,很容易拿到。 标注数据的质量不高,存在或高或低的标注错误。 不会覆盖无监督类学习。 相比于无监督学习,learning with nois...
这次的 paper reading,聚焦 Learning with noisy label: 有一定量的标注数据。-- 通过搜索引擎、公开数据集等,很容易拿到。 标注数据的质量不高,存在或高或低的标注错误。 不会覆盖无监督类学习。 相比于无监督学习,learning with noisy label 更贴近深度学习在工业界的落地。 典型的状态如下: 初始阶段有一定量的...
Learning with noisy labels means When we say "noisy labels," we mean that an adversary has intentionally messed up the labels, which would have come from a "clean" distribution otherwise. This setting can also be used to cast learning from only positive and unlabeled data....
假设你的模型已经能够解决训练集里的噪声问题了，那么对大致同理同分布的验证集也是同样适用的，即使验证...

with noisy labels. If the loss function satisfies a simple symmetry condition, we show that the method leads to an efficient algorithm for empirical minimization. Second, by leveraging a reduction of risk minimization under noisy labels to classification with weighted 0-1 loss, we suggest the use...

2.1 LEARNING WITH NOISY LABELS 现有的训练带噪声标签的dnn的方法大都是为了修正loss函数。修正方法可以分为两类。第一种方法对所有样本一视同仁,通过重新标记噪声样本来显式或隐式地纠正损失。对于重标记方法,对噪声样本的建模采用有向图模型(Xiao et al., 2015)、条件随机场(Vahdat, 2017)、知识图(Li et al...
