Acknowledgments

Our code uses some dataloaders from Torchmeta.

Code in maml folder is based on the extended implementation from Torchmeta and pytorch-maml. The code has been updated so that baseline scores more closely follow those of the original MAML paper.

Code in protonet folder is based on the implementation from MetaOptNet. All .py files in this folder except for dataloaders.py and optimize.py were adopted from this implementation and modified afterwards. A copy of Apache License, Version 2.0 is available in protonet folder.
