首先在给定的测试时的support set,support set是一个C个类别(原则上这C个类别和train set中的M个类别是不相交的,这样才符合one-shot learning的本质),且每个类别下只有一个样本的数据集,现在给定一个query,将query和support set中的样本输入到孪生网络中,得到query和每个样本之间的概率分数,在这里因为是one-shot,...
Few-shot Learning 是Meta Learning 在监督学习领域的应用。Meta Learning,又称为 learning to learn,在 meta training 阶段将数据集分解为不同的 meta task,去学习类别变化的情况下模型的泛化能力,在 meta testing 阶段,面对全新的类别,不需要变动已有的模型,就可以完成分类。 形式化来说,few-shot 的训练集中包含...

In this article, I will acquaint you with the notion of Few-shot learning, focusing on the widely-used approach known as SetFit for text classification. To begin our learning journey, we'll start by revisiting Traditional Machine Learning techniques. Afterward, we'll transition into the realm ...
摘要: Due to the limited length and freely constructed sentence structures, it is a difficult classification task for short text classification. In this paper, a short text classification framework based...关键词: Convolutional neural networks Deep learning Few-shot learning Text classification ...
Few-shot learning是meta learning在监督学习领域的一种应用场景,我们training阶段将数据集按类别分解为不同的meta-task,去学习类别变化的情况下模型的泛化能力,在testing阶段,面对全新的类别以及每个类别仅有少量数据,不需要变动已有的模型,就可以完成分类。
Many deep learning architectures have been employed to model the semantic compositionality for text sequences, requiring a huge amount of supervised data for parameters training, making it unfeasible in situations where numerous annotated samples are not available or even do not exist. Different from ...
PET: Pattern Exploiting Training ,是一种半监督学习方法,应用于 few-shot learning ,流程为: 1、训练PVP模型(prompt,supervised):对每一种 prompt pattern,使用单独的 PLM 在 有标签数据集 上微调得到多个「PVP模型」。 2、在这个过程中,Task Description(textual explanation) 可以让模型...
zero-shot learning/one-shot learning/few-shot learning 都是meta learning领域的一个分支,meta learning在计算机视觉领域的研究相对成熟,但是在NLP领域,尚处于发展阶段。 笑个不停:few-shot learning/one-shot learning 小样本/零样本学习 学习笔记(持续更新)55 赞同 · 3 评论文章 ...
