3. Proxy-label Methods 代理标签方法是使用预测模型或它的某些变体生成一些代理标签,这些代理标签和有标记的数据混合一起,提供一些额外的训练信息,即使生成标签通常包含嘈杂,不能反映实际情况。 这类方法主要可分为分为两类:self-training(模型本身生成代理标签)和 multi-view learning(代理标签是由根据不同数据视图训...
An example of this approach to semi-supervised learning is the label spreading algorithm for classification predictive modeling. In this tutorial, you will discover how to apply the label spreading algorithm to a semi-supervised learning classification dataset. After completing this tutorial, you will ...
Inductive methods, like supervised learning methods, yield a classification model that can be used to predict the label of previously unseen data points.Transductive methodsdo not yield such a model, but instead directly provide predictions. Inductive methodsinvolve optimization over prediction models, wh...
Challengesof using semi-supervised learning As we already mentioned, one of the significant benefits of applying semi-supervised learning is that it has high model performance without being too expensive to prepare data. It doesn’t mean, of course, that SSL has no limitations. Let’s discuss ...
Semi-supervised learning is the branch of machine learning concerned with using labelled as well as unlabelled data to perform certain learning tasks. Conc

Finally, the gradient descent method was applied to optimize the weights of the student model, and the teacher model weights were updated using EMA. Algorithm 1 Training Algorithm of the Method Input: the training set D=DL∪DU; the corresponding label map Y; 1: Initialize the model parameters...
论文名字:Multi-Task Label Embedding for Text Classification 动机 文本分类中的多任务学习利用相关任务之间的隐式关联来提取共同特征并获得性能增益。然而,以往的研究大多将每个任务的标签视为独立的、无意义的one-hot向量,导致潜在信息的丢失,使得这些模型很难联合学习三个或更多个任务。 预学习概念 文本分类是一种...
