Prototypical network 零样本

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. Webb零样本学习不同于少样本学习,其meta-data向量Vk不是由训练集中的支持样本生成的,而是根据每个类的属性描述、原始数据等生成的。 这些信息都是可以提取确定或者从原始数据中得到的。 原形网络也能过灵活的转变 …
