Webb在论文中作者提出了一种新的基于度量(Metric-based)的少样本学习模型—— 原型网络(Prototypical Networks) 。 原型网络首先利用支持集中每个类别提供的少量样本,计算它们的嵌入的中心,作为每一类样本的 原型(Prototype) ,接着基于这些原型学习一个度量空间,使得新的样本通过计算自身嵌入与这些原型的距离实现最终的分类,思想与聚类 … Webb22 apr. 2024 · Wrapping up. Prototypical Networks is a simple method for few-shot learning based on the idea that one can represent each class by the mean of its …

WebbMatching Networks [32] produce a weighted nearest neighbor classifier given the support set, while Prototypical Networks produce a linear classifier when squared Euclidean distance is used. In the case of one-shot learning, c k= x ksince there is only one support point per class, and Matching Networks and Prototypical Networks become equivalent. Webb11 okt. 2024 · The prototypical network is a prototype classifier based on meta-learning and is widely used for few-shot learning because it classifies unseen examples by constructing class-specific prototypes without adjusting hyper-parameters during meta-testing. Interestingly, recent research has attracted a lot of attention, showing that … nissan service advisor training
