few-shot 链接预测任务总是针对特定关系定义的。在预测时,通常有多个三元组需要预测,在支持集Sr的情况下,我们称所有待预测三元组的集合为query set Qr = {r : (hj, ?)}。 少样本链接预测方法的目标是获得预测关系 r 的新三元组的能力,而只需观察关于 r 的几个三元组。因此,它的训练过程是基于一组任务 ...

KG Completion (KGC) is a popular technique for knowledge supplement. However, there are two ...
在目标场景中,同构图或异构图都可以通过链接预测任务来进行预训练。在预训练中使用链接预测源于在图上,链接获取的成本较低。对于下游任务,聚焦处理异构图,并关注few-shot场景下的节点分类和图分类。 Proposed Model: HGPROMPT Overall Framework (a),(b)阶段,对于给出的同构图与异构图,都使用链路预测作为预训练任务...
On the other hand, few-shot imitation is by no means the only form of cultural transmission16. Here, we provide a recipe for learning a few-shot imitation ability tabula rasa. Nevertheless, many of our methods are independent of the particular setting of imitation. We want to know how the...
To prevent PLMs from overfitting on small training data, LoRA is applied to constrain model updates to a limited number of parameters (left). c The meta-trained model is then transferred to the target few-shot learning task. FSFP treats fitness ...
Abstract:In Generalized Few-shot Segmentation (GFSS), a model is trained with a large corpus of base class samples and then adapted on limited samples of novel classes. This paper focuses on the relevance between base and novel classes, and improves GFSS in two aspects: 1) mining the similar...
