Multi-label Learning is a form of supervised learning where the classification al-gorithm is required to learn from a set of instances, each instance can belong to multiple classes and so after be able to predict a set of class labels for a new in-stance. This is a generalized version of...
写在前面:多数关于多任务学习(Multi-task learning)的文章、综述或者paper都聚焦于网络结构的迭代与创新;然而,对于多任务学习Loss的优化也非常重要。本文基于多任务学习在2020年的一篇综述——《Multi-Task Learning for Dense Prediction Tasks: A Survey》中的部分内容,尽量用通俗易懂的方式来聊聊多任务学习优化的问题...
When collecting multi-label annotations, it may be more efficient for a crowd worker to mark the presence of a specific class as opposed to confirming its absence. Our setting is most closely related to positive-unlabeled (PU) learning [33] – see [1] for a recent survey focused on ...
