Bayesian Meta-Learning Approaches 第一个想到的方法是让模型直接输出关于$y\^{ts}$分布的参数值。 好处是简单、能够结合其他的多种方法。 坏处是不能得到模型函数的不确定性原因,如确定数据点之间的不确定性如何关联。只能够表达有限的相对于目标ytsy^{ts}yts的分布类别。倾向于产生低校准的不确定性估计。

Overview.We introduce a Bayesian meta-learning method based onGaussian Processes (GPs)to tackle the problem of few-shot learning. We propose a simple, yet effective variant of deep kernel learning in which the kernel is transferred across tasks, which we callDeep Kernel Transfer (DKT). This ap...
We introduce a novel Bayesian meta-learning approach that aims to address this in two key settings: (1) predictions for new patients (same population as the training set) and (2) adapting to new patient populations. Our main contribution is in modeling similarity between causal mechanisms of ...
Recent works have used meta-learning to view the problem of estimating the maximum a-posteriori causal graph as supervised learning. Yet, these methods are limited when estimating the full posterior as they fail to encode key properties of the posterior, such as correlation between edges and ...
