的泛化误差,将episodic training paradigm分为两步:(1)N-way,在 中随机抽取N个类;(2)K-shot,在C中随机抽取 。我们采用支持集S作为测量标准,并使用查询集Q来优化模型的参数。同样可以在测试集D中提取支持集S和查询集Q来评估性能。我们将训练策略应用于我们的小样本实验(第4节),我们也考虑了1-shot(K= 1)...

提出了一个design the attentive squeeze network (ASNet),解决few shot learning下的图像classification和segmentation。 给定target class的query image和support image,目标是识别support class image的存在,而后在query class image的foreground mask。 ASNet的框架如下。Each input correlation, intermediate feature, and...
本文受few-shot learning的启发,具体来说,CNN模型被用来训练学习一个度量空间。换句话说,在数量充足、与目标数据集(我的理解是测试集)不同的具有标签的数据集上,训练一个CNN模型来提取泛化的特征。一旦训练完成,模型可以从较小的标记目标数据集(测试集)中提取特征。 本文提出一种 deep few-shot learning(DFSL)来...

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...

In this work we develop a deep few-shot learning method for the classification of RS scenes. The proposed method is based on prototypical deep neural networks combined with SqueezeNet pre-trained CNN for image embedding. In this paper, we report preliminary results using the two RS scene ...
当我看完 《Generalizing from a few examples: A survey on few-shot learning》 这篇文章的时候,我对于机器学习又有了一种新的认知,与其说它让我理解了什么是Few-shot learning,不如说它让我明白了如何更好地处理机器学习问题,不论是科研还是在实际应用当中(可以说是所有其它模型算法),都可以从文章指出的三...
