摘要:

为了发现潜在数据的内在类间转移概率,带噪声转移的学习已经成为在损坏标签上进行鲁棒深度学习的重要方法。现有方法试图通过预先假设具有属于特定类别的1概率的强置信锚点来实现这种转变知识,这在实践中通常是不可行的,或者直接联合估计转变矩阵并从噪声样本中学习分类器,这总是导致由错误注释信息误导的不准确估计,特别是在大噪声情况下。为了缓解这些问题,本研究提出了一种新的元转换学习策略的任务。具体地说,通过一个小的集合的干净的标签的Meta数据的声音引导,噪声转移矩阵和分类器参数可以相互改善,以避免被噪声训练样本,而不需要任何锚点假设。此外,我们证明了我们的方法是正确估计所需的转移矩阵的统计一致性保证。大量的合成和真实实验验证了我们的方法可以更准确地提取过渡矩阵,自然遵循其比现有技术更强大的性能。讨论了它与标签分布学习的本质关系,说明了它在无噪声情况下也有良好的性能。

英文摘要:

To discover intrinsic inter-class transition probabilities underlying data, learning with noise transition has become an important approach for robust deep learning on corrupted labels. Prior methods attempt to achieve such transition knowledge by pre-assuming strongly confident anchor points with 1-probability belonging to a specific class, generally infeasible in practice, or directly jointly estimating the transition matrix and learning the classifier from the noisy samples, always leading to inaccurate estimation misguided by wrong annotation information especially in large noise cases. To alleviate these issues, this study proposes a new meta-transition-learning strategy for the task. Specifically, through the sound guidance of a small set of meta data with clean labels, the noise transition matrix and the classifier parameters can be mutually ameliorated to avoid being trapped by noisy training samples, and without need of any anchor point assumptions. Besides, we prove our method is with statistical consistency guarantee on correctly estimating the desired transition matrix. Extensive synthetic and real experiments validate that our method can more accurately extract the transition matrix, naturally following its more robust performance than prior arts. Its essential relationship with label distribution learning is also discussed, which explains its fine performance even under no-noise scenarios.
