1. Proposed Taxonomy
1.1 Meta-Representation (What?)
Parameter Initialization
参数初始化最典型的例子是MAML,学习到的meta knowledege是任务的初始化参数,基于这个初始化参数,新的任务可以更快地学习。
参数初始化最大的问题是,外层任务与内层任务可能要学习相同数量的参数。
Optimizer
Feed-Forward Models
Embedding Functions(Metric Learning)
Losses and Auxilliary Tasks
1.2 Meta-Optimizer (How?)
1.3 Meta-Objective (Why?)
